From classroom to COP30: Questions from children to climate leaders about Ocean protection

From classroom to COP30: Questions from children to climate leaders about Ocean protection

If a group of 7โ€“11-year-olds could interview delegates at COP30, what would they ask? 

Well in November 2025, Ocean Generation made this happen. We worked with 5 young Eco Ambassadors at Ballard School in New Milton, UK as they interviewed Professor Matt Frost, Head of International Office at Plymouth Marine Laboratory as part of the COP30โ€™s Virtual Ocean Pavilionโ€™s series of youth-led interviews.  

What is COP?
COP (Conference of the Parties) is the UNโ€™s annual climate summit. During the conference, parties negotiate climate action and review progress. COP is also a platform for scientific studies and activism. Read more about COP here. 

Ocean Generationโ€™s Youth Engagement Lead, Dr Gemma Connell, mentored the young people through the process and was so proud when they wrote their own (very difficult!) questions for Matt, giving him a bit of a grilling!  

It was heartwarming to witness Mattโ€™s honesty in his responses to the young people. He discussed where the problems are in the COP space, and most importantly โ€“ what we can all do to protect our Ocean.  

Join the Eco-Ambassadors as they ask Professor Matt Frost the important questions around COP30, the importance of the Ocean and what his favourite sea creature is.

So, you wake up at COP30, what are you doing? What does you day look like? (Freddieโ€™s question) 

Mattโ€™s answer: 

Wake up, check the times on everything. You donโ€™t want the changing time zones to lead to you missing events and meetings.  

Planning where to be that day, making a list of places and times I need to be somewhere.  

The first day and the start of every day includes a lot of security. Making sure everyone has identification and the right badges to get through the security measures that are in place protecting some of the world’s most important people. 

COP can involve hundreds of thousands of people, so just working out where everything and everyone is, is a challenge. Got to make sure you know where the good coffee shops are.  

โ€œThe fun bit is that you walk around, and you meet all sorts of people.โ€  

Not just meetings or speaking events, but you might find yourself doing some media as well. 

โ€œRecently I was at a COP when I bumped into Tom Heap, who is one of the presenters on Countryfile. He said, โ€˜do you mind doing an interview while youโ€™re here that we can put on Sky News?โ€™โ€ 

Every evening there will be a reception, meeting all sorts of people from government ministers to scientists.

What are your expectations coming to the COP30 and what would you consider a successful result for the Ocean? (Tobyโ€™s question) 

Mattโ€™s answer: 

โ€œFor many years, when people came to these meetings, they were all worried about what was going on on the land.โ€ Matt noted how the conversations would focus more on forests, trees and farming, โ€œbut nobody really thought about the Ocean.โ€ 

โ€œSo, over the years, weโ€™ve had to explain to people that our planet โ€“ and Iโ€™m sure you know this, being Eco Champions โ€“ is mostly water. The Ocean is most of our planet. So, one of the main things that is a success every time we go to these meetings is to make sure that everybody is talking about the Ocean.โ€

Every leader talking about the Ocean is a success. The next step is encouraging action.

The people at these meetings donโ€™t have the power, they can go back to their governments to convince them to act. 

For example, the UK government going home and taking direct action to address the issues in the Ocean through laws and funding would be a real success from COP30.   

The Ocean has gradually grown in prominence on the global stage.

The Ocean has gradually grown in prominence on the global stage.  

Ocean Generation’s note:

Six years ago, COP25 recognised the connection between Ocean and climate, COP26 called for Ocean action to be integrated in work programs and COP27 encouraged countries to include the Ocean in their national climate goals.  

At COP30, the Ocean was formally included in the COP30 Action Agenda. It was the first time a COP decision included a specific Ocean angle, with goals and commitments. This included investing in marine conservation and renewable energy, reducing the environmental and ecological impacts of shipping, supporting aquatic food solutions and reducing the impact of coastal tourism.  

Practical tools were launched at COP30 to help achieve the goals. An Ocean Breakthrough Implementation Dashboard was launched to monitor country progress across those five areas (nature conservation, renewable energy, shipping, marine food and tourism). The Marine Biodiversity and Ocean Health Breakthrough and Roadmap gives the standards and methods to tackle Ocean assessment and actions.  

While COP30 included the Ocean more deeply than previous COPs, there was a lack of financing and binding agreements to ensure countries take action. It is now over to them to build on the outcomes of COP30 and take Ocean action.  

How can governments encourage private companies to not use single use plastic? (Leoโ€™s question) 

Mattโ€™s answer: 

If I could get a brilliant answer to that it would solve one of the world’s biggest problems. So, I will do my best and honestly, Leo, if you and your friends have got ideas… we need some help with this.โ€ 

As well as a pollution problem, plastic is also a climate problem, as 99% of plastics are made from fossil fuels. 

Governments like the UK have been banning things like plastic straws, microbeads in cosmetics and charging for plastic bags. 

Should we ban everything? โ€œI donโ€™t think that will help ultimately…โ€. It is a global problem and needs to be addressed globally. The Global Plastics Treaty is an opportunity for governments to make a real difference. Read more about the treaty here.  

Companies are willing to cut down on plastic but need incentives to do so. Encourage is a great word in the question. 

โ€œThey [world leaders] can make it difficult by putting taxes [on plastic] and making it more expensive to use single use plastic. But ultimately… governments will only do so much.โ€  

Government action can be encouraged by what we buy and say.  

99% of plastics  are made of  fossil fuels. Posted by Ocean Generation, leaders in Ocean education.

Ocean Generation’s note:

The difficulty in banning all plastics, is where we havenโ€™t yet found an affordable alternative which does the same thing as plastic but doesnโ€™t have the impact on the environment.  

This is particularly difficult in industries such as healthcare, where single use plastic is often used to keep patients, doctors and nurses safe. We canโ€™t ban all plastics without looking at the other consequences that might have โ€“ context is very important! Read more about if plastic is good or bad here

Are there plans to introduce whale friendly cruise routes to reduce noise pollution in the seas? (Lilyโ€™s question)  

Mattโ€™s answer: 

Yes there are plans for whale friendly shipping, but we really need the shipping companies to start doing this now.โ€ 

Ships are big contributors to climate change, producing air pollution as they burn fossil fuels to power their engines.  

There are much more ships on the Ocean at any one point โ€“ over 70,000. There are two main ways they cause issues for marine life such as whales โ€“ noise pollution and ship strikes. 

Whale friendly cruise routes hope to minimise the impact of both of those things. The International Maritime Organisation and the International Whaling Commission are trying to implement rules on shipping. These include go slow zones where whales are known to feed and live, and special routes that avoid whale โ€œhotspotsโ€.  

It is down to the individual ships, shipping companies and cruise companies to act on the advice of the IWC and IMO.  

How marine shipping routes and whale's migration routes overlap. Explained by Ocean Generation.

Ocean Generation’s note:

Exact numbers of whales killed by ship strike are difficult to quantify, as data suffers from underreporting.  But recent work has shown that global shipping traffic overlaps with about 92% of whale speciesโ€™ ranges. Of that, only 7% of the areas that are high-risk for whale-ship collisions have any protective measures. Protecting just 2.6% more of the Ocean would eliminate many high-risk areas with minimal impact to shipping times.  

As Matt says, there are two main solutions. Slower ships give all marine life more time to dive or swim away, avoiding collision. Slowing ships to 10 knots can reduce the the number of whale deaths by 30%.  

The other approach is by re-routing ships from collision hotspots. In the Mediterranean, rerouting ships away from the Hellenic Trench has reduced the risk of collision by an estimated 27%.  

95% of hotspots fall within the exclusive economic zones of a country, so, each country can implement protective measures in coordination with the IMO recommendations. Whale safe routes are in reach.  

Does creating the infrastructure in order to host COP30 and transporting leaders there outweigh the positive outcomes of the conference? โ€ฏDo you assess the carbon footprint and is there a plan to offset this? (Seanโ€™s question) 

Mattโ€™s answer: 

The concern is that we might not have these conversations if we werenโ€™t all in the same room. Yes, we carbon offset but there is going to be some environmental impact. We think the positives outweigh the negatives.  

โ€œAt the moment we feel that if we didnโ€™t go, whoโ€™s going to be there to speak up for good science, to speak up for the Ocean, to speak up to actually look after things? And the danger is that, if all the people who feel very strongly about carbon decide not to go to the COP for the reasons youโ€™ve said, then it could be left with the people that donโ€™t really care much about it.โ€  

Ocean Generation’s note:

One of the intentions of hosts Brazil was to deliver a carbon-neutral COP30. They delivered this by offsetting their calculated emissions. They calculated that COP30 produced 130,000 tonnes of carbon dioxide or equivalent greenhouse gases. To counter this, they purchased 130,000 UN-certified carbon credits. The money for these credits goes towards carbon-negative projects, so COP30 is carbon-neutral in principle.  

However, this calculation only considers the emissions generated by hosting. The bulk of emissions are likely generated by the travel of attendees. There is no comprehensive calculation of these emissions. A large part of that relies on the attendees doing what they can to reduce environmental impact.  

โ€œYou can ask me again next year and maybe Iโ€™ll answer differently, but this year the positives outweigh the negatives.โ€  

Was COP30 carbon neutral? Explained by Ocean Generation.

Is COP30 going to be used for fossil fuel deals like the last one? (Seanโ€™s question) 

Mattโ€™s answer: 

โ€œI canโ€™t promise that that will never happen at any COP.โ€   

Some people will want to see things stay as they are, but there are enough people with good intentions there to know that good things will come out of it. Multilateralism (global cooperation), connecting climate change messages to individuals and accelerating implementation are all main aims of this COP.  

Iโ€™m hoping the good things will outweigh the others.  

Ocean Generation’s note:

At COP29, there was backlash against the hosts, Azerbaijan, as one of their senior officials was found to be conducting meetings to coordinate fossil fuel deals. Find out more of what happened at COP29 in our article here.  

What is the extent of the impact of pumping carbon back into the Ocean underneath the seabed? (Lilyโ€™s question) 

Mattโ€™s answer: 

Itโ€™s possibly helpful, capturing carbon dioxide from the atmosphere and tapping it. However, there are risks โ€“ if it leaks it can cause harm to marine life and return the carbon to the atmosphere. 

Weโ€™re asking that we [humans] donโ€™t do it until we know more about the effects of it.  

โ€œIf you went to the doctor and said, โ€˜I feel really poorly,โ€ and the doctor said โ€˜well, Iโ€™ve got some medicine for you… I donโ€™t know if it works very well, and it might make you really ill, but I donโ€™t actually know that we havenโ€™t tried it.โ€™ Would you take that medicine?  

Impact of pumping carbon back into the Ocean: explained by Ocean Generation.

What key messages would you like us to share with our school community in order to look after the Ocean better? (Freddyโ€™s question) 

Mattโ€™s answer: 

There is an ongoing problem that people donโ€™t really understand the Ocean. They donโ€™t know what is in it, they donโ€™t really understand it, and they donโ€™t know that we rely on it.  

We need to remind people that most of our planet is Ocean. When the Ocean is healthy, we are healthy.  

We rely on the Ocean for our food, our breathing air and our mental health.  

If we look after the Ocean, it will look after us.

Tobyโ€™s surprise question: What is your favourite marine animal

Mattโ€™s answer: 

Mattโ€™s answer: the leafy sea dragon!  

Ocean Generation’s note:

The leafy sea dragon is a fish closely related to seahorses and pipefish. The name of its genus, Phycodurus, comes from the Greek words for seaweed (phรปkos) and skin (derma), encapsulating its amazing camouflage. It can change the colour of its skin to match the seaweed around it and moves through the water like a drifting frond. 

Leafy seadragons typically swim solo, but will court each other through dance, mirroring each other’s movements. Males carry the eggs for 6-8 weeks on a specialised patch under their tail, before โ€˜giving birthโ€™ to 100-250 20mm baby leafy sea dragons (about the size of a peanut).  

The leafy sea dragon is a fish closely related to seahorses. Posted by Ocean Generation.

Matt asked the students: what would the Eco Ambassadorsโ€™ message be for him to take to COP30?  

Toby answered, โ€œPlant more trees!โ€  

A week later, the Eco Ambassadors planted 30 saplings after school, doing their bit to live up to Tobyโ€™s โ€œplant more trees!โ€ answer.  

Alex Bellars, teacher at Ballard School said: 

โ€œOur Eco-Ambassadors absolutely loved taking part in the Virtual Ocean Pavilion interview with Professor Matt Frost on 6th November, 2025. It was inspiring to know that their voices and ideas formed even a tiny part of the global conversation at COP30!  

It was especially cool to know that our pupils were the youngest participants in the Virtual Ocean Pavilion – and therefore possibly at the whole of COP30 itself. And it was wonderful to see Toby grab the chance to put Matt on the spot with an unplanned bonus question!โ€

Is Seaweed the Secret to Ditching Plastic? Explained.

Is seaweed the secret to ditching plastic? Explained by Ocean Generation, leaders in Ocean education.

Plastics play an essential role in modern human civilisation. They are incredibly versatile, providing function in almost all aspects of our lives. 

Why plastic is a problem for us and the Ocean

Fossil-based plastics are infamous for their long-lasting impact on the environment, taking up to hundreds or thousands of years to fully break up. Along the way, they harm wildlife and people both as large plastic items and microplastics. 

The impact of this is demonstrated perfectly in the Ocean, where wildlife can unknowingly eat or interact with plastics. It has been observed that every species of sea turtle has been affected by entanglement in plastic. 

Plastics have another big problem. Theyโ€™re sourced from oil, which contributes to their damage to the environment. 3.4% of global emissions were contributed by the plastic lifecycle in 2019, with 90% of that being emissions from production and converting fossil fuels into plastic making materials. 

What's wrong with plastic - for us and the Ocean? Explained by Ocean Generation.

What are microplastics

Microplastics are plastic particles less than 5mm in size formed from the breakup of plastic. Theyโ€™re found across the planet, from deep in the Ocean to the snow high in the mountains. Theyโ€™ve even been found in the human body.ย  We donโ€™t fully know yet what that means for our health, but we do know they harm marine life and can travel up the food chain. ย 

Single use plastics, like plastic bags and straws, are big contributors to plastic waste, making up approximately half of all plastic waste.ย  We only use them once and then throw them out, which means more and more plastic needs to be made to maintain supply.ย 

What are microplastics?

What is the solution to our plastic usage problem? 

Recycling is one solution to this problem, but in 2019, the OECD estimated that only 9% of plastics are recycled.The rest is disposed of in landfill sites (50%), incinerated (19%), or goes unregulated into uncontrolled landfills, fires or the environment, including our Ocean (22%). On top of this, not all plastics are recyclable. Is there another solution? 

What are bioplastics

According to European Bioplastics,  โ€œbioplasticsโ€  are either bio-based, biodegradable, or both. Bio-based plastics are plastic alternatives which, rather than using fossil fuels to source the plastic, use biological feedstock (materials) like starch or cellulose.

Bio-based plastics are not necessarily biodegradable. Biodegradability has no clear definition or criteria, but in general, a product is biodegradable if a substance can be broken down into water, biomass and gasses. As a result of this definition, biodegradable fossil-based plastics can be considered as bioplastics.

What are the different types of bioplastics

There are 3 distinct generations of bioplastics, all defined by what theyโ€™re made of:  

  • 1st generation bioplastics use food crops like corn or soybeans. 
  • 2nd generation bioplastics use non-food crops like grass and wood. 
  • 3rd generation bioplastics use seaweed and algae. 
What are bioplastics made of? Posted by ocean Generation.

Whatโ€™s the major difference between using seaweed and crops

The major difference between crop-based and seaweed-based bioplastics is where they are planted.ย 

The first two generations of bioplastics use fertile land which could be used for growing other crops.ย ย 

Seaweed bioplastics are bio-based plastics and derived from seaweed. Seaweed bioplastics donโ€™t have the same problems as the other generations as seaweed grows in the Ocean (which there is much more of than fertile land on Earth), and require only sunlight, atmospheric CO2 and the naturally nutritious waters of the Ocean.ย ย 

They are a relatively new discovery; the first seaweed bioplastics company was established in 2010. Lady Gagaโ€™s music career began before bioplastics were commercial.ย ย 

How are seaweed bioplastics made? 

The first step is letting the seaweed spores grow before they are put into a seaweed farm. They are then harvested a few months later. 

The seaweed contains molecules that can be extracted via chemical processes. These have gelling and film-making (like plastic wrap, not movies) properties which make them useful in bioplastic production.

The extraction process leaves behind residuals. These leftovers can be turned into seaweed pellets which can feed back into the bioplastic making process, reducing waste. They can also be converted into methane which comes with the disadvantage of being a greenhouse gas. However, if captured and stored, it can be a carbon effective source of methane, which can be used in the chemical industry, or as a cleaner fuel than fossil fuels.  

Our molecules can be mixed with other substances like nanoclays or silver nanoparticles to improve strength or change properties like making them antimicrobial. 

Seaweed bioplastics are already used commercially in places like food packaging โ€“ thatโ€™s pretty kelp-ful! 

Seaweed is a macroalgae growing in the Ocean.

What is the environmental impact of seaweed bioplastics? 

The life cycle assessment of seaweed bioplastics looks at its carbon footprint from harvesting it from farms in the Ocean to its disposal in bins. Pilot scale assessments (these represent full production at a smaller scale) show that their production released more carbon than plastic, however, models show that scaling up production to full scale makes their carbon output less than plastics. 

What are the downsides of seaweed bioplastics? 

Making seaweed bioplastics relies heavily on farming and harvesting seaweed. This may present a problem when scaling up seaweed farms, especially to the size of being able to match plastic production, if this is even possible.ย  Seaweed farms take up space in the Ocean, and they affect organisms that are living in areas where farms are viable, like seagrasses and corals by blocking light or choking them.ย 

This problem can be mitigated by moving seaweed farms into the open Ocean and optimising growth by growing two different species in the same space. This can be done by growing buoyant kelp and non-buoyant seaweed next to each other to best use space.ย 

Seaweed can also wash onto the coast from farms and decay, releasing pollutants that were absorbed over the life of the seaweed, affecting the local environment and limiting biodiversity.ย 

There is also the problem that not all bioplastics are biodegradable. While it may be entirely possible that seaweed bioplastics specifically are biodegradable, there isnโ€™t yet enough literature to suggest that this is the case.ย 

On top of this, the definition of biodegradability has no specific time frame in which a material should be broken down in, meaning this vagueness could be taken advantage of.ย 

This reintroduces a problem that we were trying to solve, simply sourcing the plastics from elsewhere. ย 

Which plastic or alternative is the bets to choose?

Which plastic (or alternative) is the best to choose? 

There are many factors that go into considering a product: the production, the functionality (how good it is at what itโ€™s supposed to do) and the environmental cost. ย 

However, it can be difficult to remove bias. Take single use paper bags for example. At first glance, they seem much more environmental than single use plastic bags as theyโ€™re biodegradable, but when put into practice, they have a higher carbon footprint in production than plastic bags and arenโ€™t as strong. So, itโ€™s difficult to tell which of these is better.ย 

As more research goes into seaweed bioplastics, we may find solutions to the problems associated with them and have a more accurate understanding of their impact as they are produced on a larger scale. For now, it is better to avoid single use items altogether, and to use seaweed bioplastics where available.ย ย

Suggested by: Agnes, Comms teamย 

About the book

Set in a remote coastal village, in the UK, this novel follows a woman grappling with her past while surrounded by the wild, untamed Ocean. Itโ€™s atmospheric, almost poetic, and perfect for readers who love storytelling where the natural world is deeply felt.

Cover of "Whale Fall" by Elizabeth Oโ€™Connor โ€“ a literary novel set in a coastal Ocean village.

Why Agnes chose it:ย 

โ€œI enjoyed the book because it shows the connection between the Ocean and the inhabitants of a remote island, but without romanticising it. This sort of lifestyle rarely exists today so it was really interesting to learn about it through the story of a young Welsh woman, a whale, and some English researchers.โ€

11) Life of Pi by Yann Martel

About the book

While this isnโ€™t a science book, weโ€™ve added it to the list for our fiction lovers. Life of Pi is an award-winning novel about survival at sea. It explores faith and the majesty (and brutality) of the Ocean. ย 

Piโ€™s deep respect for the Ocean and its creatures makes this quite a philosophical read for Ocean lovers.ย 

Cover of "Life of Pi" โ€“ a fiction novel about survival at sea and Ocean reverence.

What is the UN Ocean Decade: Everything you need to know

We’re halfway through the UN’s Decade of Ocean Science

2025 is the year NASAs Artemis III mission hopes to land the first people on the moon since 1972, we’ll welcome the year of the Snake in the Chinese New Year, there will be a total eclipse visible across some of North America, Greenland and Europe โ€“ and 2025 marks the halfway point in the Ocean Decade.  

What is the Ocean Decade? 

In 2017 the UN General Assembly announced something exciting. 2021- 2030 would be the UN Decade of Ocean Science for Sustainable Development, or (much catchier) the Ocean Decade.  

Its vision is encapsulated in the phrase, โ€˜the science we need for the Ocean we wantโ€™. 

The science we need for the Ocean we want encapsulates the vision of the UN Ocean decade.

The aims of the Ocean Decade are;  

  • Stimulating Ocean science and knowledge generation 
  • Creating new opportunities for sustainable ecosystem development 
  • Accelerating the implementation of Sustainable Development Goal (SDG) 14: Life Below Water which is all about conservation and sustainable use of the Ocean
  • Fostering international cooperation in Ocean science. 

That is a lot of long words to say, the goal of the Ocean Decade is to put the Ocean front and centre.

How is the Ocean Decade helping the Ocean? 

The UN has identified key Ocean Decade challenges and set targets to address them. 10 Ocean Challenges, aiming for 7 Outcomes of collective impact.  

The 10 key UN Ocean Decade Challenges, posted by Ocean Generation.

Hereโ€™s a simplified breakdown of the challenges (in reverse order just to keep you on your toes).  

Challenge 10: Restore societyโ€™s relationship with the Ocean
Challenge 9: Skills, knowledge, technology and participation for all 
As the great Jacques Cousteau said, โ€œpeople protect what they loveโ€. Restoring a link between people and the Ocean, instilling stewardship through education, is key to improving its health.  

Challenge 8: Create a digital representation of the Ocean 
Challenge 7: Sustainably develop the Global Ocean Observing System  
7 and 8 offer how to deepen that knowledge of the Ocean and use technology to further it and share it. Making models, exploring further and donโ€™t forget to tell everyone about it. 

Challenge 6: Increase coastal resilience to Ocean and coastal risks
Challenge 5: Unlock Ocean-based solutions on climate change 
We can enlist the Ocean as an ally. It already absorbs up to 89% of our excess heat and has taken up 40% of carbon dioxide emitted. However, intensification of storms and rising sea levels threaten communities closest to the sea. Challenges 5 and 6 look at the practicalities of our relationship with the Ocean. 

The goal of the UN Ocean Decade is to put the Ocean front and centre.

Challenge 4: Develop a sustainable, resilient and equitable Ocean economy
Challenge 3: Sustainably nourish the global population 
Beyond that, our Ocean can be a cornucopia, providing food and resources. To ensure it is, these two aim to tackle the management and guidance needed to avoid a harmful relationship with the Ocean and benefit everyone. 

Challenge 2: Protect and restore ecosystems and biodiversity
Challenge 1: Understand and beat marine pollution 
Finally, Ocean Decade challenges 1 and 2 aim to protect and restore. Undo the harm that has been done to our Ocean, and tackle how it is still being damaged.  

For a healthy planet, we need a healthy Ocean. 

These challenges cover the full range, from prompting a sense of responsibility in people to tackling the specific threats.  

The goal is simple โ€“ nurture an Ocean that is healthy, resilient, clean, productive and safe, but also predictable, accessible and inspiring. These are the outcomes the Ocean Decade targets. (Read: Why is the Ocean so important?

We are all part of the Ocean Decade 

Ocean Generationโ€™s mission is to bring the Ocean to everyone, everywhere.  

We translate complex Ocean science into engaging content and run three youth engagement programmes for 3 โ€“ 25-year-olds. Our Ocean Intelligence approach is endorsed by UNESCO as an Ocean Decade Project; making us part of Ocean Decades solutions.  (Which challenge are we meeting?).

Look through the challenges, see if you can engage with any.

UN Ocean Decade: First look complete 

Over the coming year, weโ€™ll check in with the Ocean Decade. We will explore the plans it has, discover how it ties in with the different elements of the work we do, and summarise the progress it has made in a final check up at the end of the year.  

We are all part of the UN Ocean Decade.

Can traditions become Ocean-friendly? The story of Thailandโ€™s Loy Krathong Festival

Ocean Conscious Future with Traditions, Wavemaker Story posted by Ocean Generation

Our Ocean, rivers, lakes, canals and other bodies of water have provided us with so much for centuries.

They sustain ecosystems, support livelihoods and offer vital resources. Itโ€™s no wonder that they are appreciated and celebrated worldwide.  

In Thailand, a full moon night in November, during the Loy Krathong Festival, is dedicated to worshiping the goddess of water. 

The Loy Krathong Festival involves floating a โ€˜krathongโ€™ (a small floating lantern). This is an act of paying gratitude to the goddess that personifies all bodies of water and apologising to her for polluting the waterways.

Each year, I celebrate Loy Krathong dressed in my traditional Thai dress, making the krathongs and sometimes teaching younger students to do the same. Iโ€™ve floated them in a river, swimming pool, pond and even virtually with my school class through a website.

This tradition has been ongoing since the 14th century and with a growing population, the Bangkok Metropolitan Administration (BMA) reported collecting 640,000 krathongs in 2023. With this vast amount, the environmental damage to the waterways cannot be overlooked. 

The materials krathongs are made of make a huge difference

Traditionally krathongs are made using a banana tree trunk, banana leaves, flowers, and candles. In the past, plastic and styrofoam were popular materials but since have reduced in numbers due to awareness of their adverse environmental impacts.ย ย 

Materials that do not decompose have numerous impacts on wildlife, human health and economic costs. Aquatic animals can mistakenly ingest these materials or become entangled in them, leading to injuries. Microplastics and chemical leaching can lead to health issues from making their way up to the food chain.

The economic repercussions include the expense of clean-up efforts and the impact on tourism. Polluted waterways could reduce the appeal of natural sites, potentially deterring and disappointing tourists.ย 

Recently, bread krathongs appeared with the idea that they would leave no waste, as fish would consume them. However, when excessive amounts of bread krathongs were floated, they ended up rotting as not all the bread was consumed. Since then, there has been an increase in the range of feasible creative alternatives.ย

How is the tradition of the Loy Krathong Festival becoming more sustainable? 

BMA reports that 96.75% of the krathongs were made with environmentally friendly materials in 2023, a 1.05% increase from the previous year. In recent years, there has been a huge experimentation of materials people have brought to celebrate with. Some examples include ice, coconut shell, and cassava which take a short time to disintegrate. 

Technology and innovation can be used to our advantage in allowing people to participate in events like Loy Krathong Festival without physically floating krathongs to reduce environmental impact.

In 2023, a technology known as projection mapping allowed visitors to doodle their krathong design on paper. These were then projected onto a river in Bangkok where 3,000 digital krathongs were floated. There are also multiple online platforms where people can write out their wishes and watch an animated krathong float across the screen within the comfort of their own homes.

For those who still want to continue the tradition in its original form, people are embracing the practice of floating one krathong per family or group of friends to reduce the number of krathongs that need to be collected. 

Experimentation and exchange of ideas can create a ripple effect, leading to more impactful solutions that enable more people to help continue tradition responsibly while enjoying it in new and innovative ways. 

Seeing how tradition and environmental responsibility can go hand in hand is encouraging to witness. Itโ€™s inspiring to see how people are becoming aware of their environmental impact, striving for greater sustainability through creativity and innovation.

This is just one example of a tradition that demonstrates how cultural practices can adapt to modern environmental challenges. As we continue to innovate and integrate sustainability into various customs, it is clear that we hold power and capability in honoring both heritage and the health of our Ocean.

The power of water and the science of passive coolingย 

The science of passive cooling: A Wavemaker Story posted by Ocean Generation

When interests collide: My love of water and fascination with ancient architecture.ย 

I have always been fascinated by, and attracted to, water.

My parents would vouch for the fact that I immediately seek out the nearest body of water whenever we have the opportunity to travel… whether that be the warm Caribbean Sea, the stunning beaches of the Hamptons, or the cold glacial lake water in the Adirondacks in Upstate New York. And as a child, they could never get me out of the bathtub!

My natural curiosity and desire to learn has led me to study various subjects of interest in STEM disciplines, and through my university studies I have discovered a genuine passion for ancient architecture and the associated technology and building techniques.ย 

Iโ€™m a huge fan of interdisciplinary research (i.e. combining strategies and information from across disciplines), which leads me to introduce an unlikely connection to our Ocean, or more correctly water, that I discovered while researching the “Scirocco rooms” of Sicily, Italy.

Scirocco Room, where the passive cooling force of water was used.

How water was used to cool scirocco rooms hundreds of years ago.ย 

The “scirocco rooms” are not rooms in the commonly understood sense, but rather man-made, underground caves. From the art historical perspective, they are important social gathering spaces.

Scirocco rooms were mainly constructed and used in the city of Palermo and rely on ancient technology to facilitate passive cooling.ย 

During the summer, the dry and sandy Scirocco Winds from the Sahara Desert in Africa blow across to Sicily and send temperatures skyrocketing … to upwards of 40ยฐC! Hence the need for a naturally cooled space, especially before the invention of air conditioning. These “rooms” were lavishly decorated in the 16-19th centuries and used as an escape from the sweltering heat of the summer months.

What is passive cooling anyway?

It is the process of naturally cooling the air flowing through a space without the use of external power or energy. So, the natural cooling properties of convection currents, properties that are hugely amplified in the presence of water, created a comfortably cooled space.ย 

View leading to the scirocco rooms, where passive cooling was used
Views of the tunnel leading to the scirocco room. On the left is the base of the โ€œwind-towerโ€ and on the right is the qanat (Arabic for โ€˜canalโ€™), covered today.
Image credit: Saeli, Manfredi and Enrico, 2022. “La Camera Dello Scirocco Di Villa Naselli di Gela A
Palermo.” La Camera Dello Scirocco – Periodico di Arte Cultura e Societร .

How passive cooling works in a scirocco room:ย 

  • Water flows from a natural spring across the terrain of Palermo to the scirocco room. Amazingly, the clay terrain naturally filters the water, and when it arrives in homes, farms or scirocco rooms it is sparkling clean!ย 
  • The natural course of the water (flowing entirely due to gravity) is diverted into scirocco rooms through man-made canals designed after the Ancient Persian structure called qanat (process explained later in diagram). ย 
  • The flow of convection currents is enhanced by the evaporation of the water in the canals, cooling the air more and at a faster rate. Itโ€™s like when you hop out of the pool in cool weather, you are instantly shivering.ย 
  • The water is also directed to fountains, pools, and artificial waterfalls. This not only created a pleasant atmosphere aesthetically in scirocco rooms but also made it comfortably cooler for guests.ย 

So, we can see that the power of water, found everywhere around us and flowing naturally through all sorts of terrain, can be used as a sustainable cooling mechanism, thanks to the natural principles of physics.ย ย 

The Ancient Persian technology used to cool scirocco rooms includes qanat (the Arabic word for ‘canal’), to divert water, and “wind-towers”. The “wind-towers” act as the main point of hot air expulsion. These two features are still widespread and regularly used in the Middle East, such as in the city of Yazd in Iran.ย 

Take a look at the diagrams below to see how these “wind-towers” work and how they amplify the convection currents.ย 

Hereโ€™s what I would like you, dear reader, to take away from my exploration:ย 

By sharing my research through various formats, including now through this Wavemaker Story, I would like to encourage all readers to uncover any and all of the  wonderful and exciting connections to our Ocean… however unlikely and niche they may seem… and share this with those around you, because you never know how, or who you may inspire.  

I discovered the amazing power of water in a completely un-STEM-related context. I was able to dive deep into the history and science of the use of water in architecture and find that water tied generations of Sicilians together through this architecture.  

Our Ocean, and water specifically, hold great potential for ecological and sustainable solutions to current pressing issues as in the case of passive cooling. Our ancestors knew this quite well and I believe there is much to learn from pre-industrial societies.

Green tourism and Thailand’s unexpected wildlife revival

Green tourism and wildlife revival in Thailand. A Wavemaker Story by Ferra, posted by Ocean Generation

Being well into summer, tourism in Thailand is at its very peak again.

It may not be obvious but the beaches that you see today have undergone a significant recovery during the pandemic. Many called it a miracle in disguise. It was a turning point that allowed for a more sustainable path forward to emerge.  

To understand why, let’s go back in time.  

During the pandemic, I took part in a beach clean-up as a high school community service project. When I arrived, I could see that all the beaches were empty, and it was unusual to see them without people as I have always linked the two together.

However, it was peaceful.

There was a lot less litter than I remember from my visit a few years ago, where there was trash every 5 meters along the coast and floating in the sea. I felt relieved for the Ocean and its community โ€“ this was probably the first break it had in a long time.

In the south of Thailand, numerous sea creatures such as fish, sharks, turtles and dugongs made unexpected appearances.

There were multiple news reports of localsโ€™ observations of sea life, indicating that there has been a promising recovery of the marine ecosystem. I even saw my first shark in the Ocean at Maya Bay in 2023, a clear and unforgettable sign I witnessed firsthand. 

But it wasn’t always like this.  

As often happens, many of the following problems occur because of us, and our impact.ย 

Pollution can arise from littering, air emissions, noise, or oil and chemicals. The most prominent is litter, ingested by marine animals or accumulating in Ocean gyres. Microplastics are another significant threat which cause toxic chemicals and disrupt food chains.ย ย ย 

In the Mediterranean Sea, marine litter accumulates 4.7 x faster during the high tourist season.ย This mostly happens due to too much waste, from lack of resources, food waste and unfamiliarity with waste systems.ย 

Anchoring and other marine activities damage corals and other marine environments such as seagrass beds. Anchors can impact 7.11% of the coral at popular sites every year. This has severe repercussions as corals are one of the slowest growing creatures โ€“ massive ones grow merely 0.3 to 2 cm per year. ย 

Green tourism in Thailand is the responsible way of travelling

How did this crisis turn into opportunity?

With the absence of tourists during the lockdown, conservationists seized the opportunity by repairing 30,000 fragments of coral in Maya Bay, Ko Phi Phi Lee; collecting rubbish and cleaning the beach.  

Moving forward, there will be rules such as limiting the number of tourists per day at popular tourist sites such as Maya Bay, Similan islands and Koh Tachai. Additionally, closing off the island at certain points of the year and increasing the strictness of regulations to move towards a sustainable future. 

Sea creatures such as sharks have made reappearances in Thailand.

What is green tourism?

Green tourism is a more responsible way of travelling. It means being mindful of the destinationโ€™s natural resources and the local community to minimise our environmental impact.

Nowadays, hotels are being more sustainable by eliminating single use amenities and promoting the re-use of products. When travelling, itโ€™s up to us, too, to make a positive impact.

Here are a few tips to be more sustainable when travelling: 

  • Support local businesses & communities 
  • Bring your own refillable water bottle (if there are no refillable stations, I often ask nearby stores/restaurants which may have large containers of water) 
  • Consider traveling during off-peak season 
  • Take public transport, walk or cycle 
  • Stay on path and avoid interacting with wildlife 
  • Avoid collecting seashells and sand 
  • Do your own research on how you can minimise your impact at the destination you plan on visiting 

After seeing the Ocean come back to life, I felt hopeful that we can indeed restore its health

With green tourism, we can reduce our ecological footprint and make sure that the breathtaking destinations will be there for us and future generations to cherish. I believe that the Ocean and people can thrive together, but for that to last, we must appreciate and take care of it.

After seeing the Ocean come back to life in Thailand, Ferra felt hopeful.

How can we protect and restore our coastlines?

Protecting and restoring coastlines starts with us.

Coastlines are the gateway to the Ocean.

Vital ecosystems like mangrove forests, seagrass meadows, coral reefs and tidal marshes exist almost exclusively in coastal regions.  

They support a high biodiversity of life and provide key nursery and breeding areas for migratory species.

Theyโ€™re also essential to the livelihoods of coastal populations, and we all rely on the important services they provide, such as carbon sequestration and protecting the coast from erosion.

Our coastlines are under threat. 

If youโ€™re wondering which of the five key Ocean threats impact our coastlines, the answer is all of them.

Because coastlines are the boundary between land and sea, our impacts are often amplified in coastal regions due to their proximity to the cause…us.  

With more than one third (2.75 billion) of the worldโ€™s population living within 100km of the coast, itโ€™s no surprise that coastal regions are heavily concentrated.

To supply the needs of this ever-growing population, coastal infrastructure development happens through:

  1. Coastal and marine land reclamation, the process by which parts of the Ocean are formed into land. 
  1. Infrastructure development for tourism, such as resorts and recreational facilities.  
  1. Development of ports, harbours, and their management.
Coastal infrastructure development, posted by Ocean Generation.

This is a key driver for habitat destruction (when a natural habitat can no longer support the species present) and biodiversity loss. It also increases the vulnerability of coastal communities to climate change impacts.

With higher frequencies of natural events like cyclones and hurricanes, risk of erosion, saltwater intrusion, flooding and other cascading climate change impacts, coastal regions have never been this vulnerable.

How can we protect and restore our coastlines? 

Enter: Nature Based Solutions (NBS). These are described by the IUCN as:

โ€˜Actions to protect, sustainably use, manage and restore natural or modified ecosystems, which address societal challenges (such as climate change, food and water security) effectively and adaptively, while simultaneously providing human-wellbeing and biodiversity benefits.โ€™ย 

In other words, when we protect and restore natural ecosystems, we provide a whole host of benefits to ourselves, too.ย ย 

This can be done by restoring degraded ecosystems to their former glory and halting further loss of existing ecosystems.

When we restore natural habitats we protect ourselves too.

Ocean Solution: Habitat restoration.

Habitat restoration is the process of actively repairing and regenerating damaged ecosystems.

Restoring coastal ecosystems such as mangrove forests, coral reefs, oyster beds and seagrass meadows allow us to address environmental challenges (such as biodiversity loss). It reduces risks to vulnerable communities (like flooding, erosion, and freshwater supply). It also contributes to sustainable livelihoods by providing job opportunities.

Thatโ€™s why at Ocean Generation, we support a mangrove restoration project in Madagascar, led by Eden Reforestation.

In 2022 alone, this project contributed to:ย 

  • Carbon sequestration and habitat restoration by planting over 4.3 million young mangrove trees.  
  • Creating sustainable livelihoods by employing around 70 people per month at the Maroalika site, with a total of 1,468 working days generated over the year.  

PSA: We plant a mangrove for every new follower on Instagram and newsletter subscriber. Sign up to our newsletter or follow us on our socials to be part of the change today. 

Interest in nature based solutions have surged lately. Posted by Ocean Generation, leaders in Ocean education.

Ocean solution: Marine Protected Areas. 

To halt ecosystem destruction and prevent further habitat loss, we must take measures to protect remaining coastal ecosystems.

One mechanism to achieve this is by implementing Marine Protected Areas (MPAs). These are designated areas of the Ocean established with strict regulations to protect habitats, species and essential processes within them.

If implemented and monitored effectively, Marine Protected Areas can provide a range of benefits across biodiversity conservation, food provisioning and carbon storage

What is the 30 by 30 target? 

In recognition of the importance of healthy and thriving ecosystems, the Global Biodiversity Framework have established a โ€œ30×30โ€ target. This calls for the conservation of 30% of the earthโ€™s land and sea through the establishment of protected areas by 2030.

The Global Biodiversity Framework calls for 30 percent of the sea to be protected.

Spoiler alert: Weโ€™re not on track to meet this goal.

According to the Marine Protection Atlas (2024), only around 8% of the global Ocean area has been designated or proposed for MPAs, and only 2.9% of the Ocean is in fully or highly protected zones.  

Research also shows that 90% of the top 10% priority areas for biodiversity conservation are contained within coastal zones (within 200-miles of the shore). We must ramp up our efforts to preserve these vital coastal ecosystems and ensure that MPAs continue to benefit both people and planet.

What are the main challenges to implementation? 

Over the past 10 years, interest in the potential of Nature Based Solutions to help meet global climate change and biodiversity goals has surged, as we have begun to truly appreciate the importance of natural ecosystems.  

Despite this knowledge and an abundance of opportunities for implementation worldwide, marine and coastal regions still lack uptake.  

We must address the barriers to implementation to accelerate the rate of success of coastal protection worldwide, including (but not limited to):

  • Conflict of interest between stakeholders i.e. blocking of protective legislation by fishing and other extractive industries.  
  • Marine and coastal ecosystems are โ€˜out-of-sight, out-of-mind’. This results in a lack of public and policy awareness of their value. As a result, Nature Based Solutions are often overlooked in favour of grey infrastructure such as seawalls.ย ย 

Increasing our understanding of the vital services provided by coastal ecosystems is critical to overcoming these barriers. 

The more we appreciate what these incredible ecosystems do for us, the more likely we are to succeed in protecting and restoring our coastlines.  

Restoring coastal ecosystems help address environmental challenges

The history of Earth Day and practical actions you can takeย 

The history of Earth Day explained, with practical actions we can all take

Everything you need to know about the history of Earth Day

Earth Day is celebrated annually on 22 April. It sparks environmental action and reminds us there is no planet B โ€“ but how and when did Earth Day start? Weโ€™re hopping in a time machine to break it down. 

Can you imagine a time when factories polluting our waterways and spitting thick, toxic smoke into the atmosphere came with no consequences? Before 1970, that was the reality.  

53 years ago, there were no legal or regulatory mechanisms in existence to protect our environment โ€“ even though climate change had started making the news in 1912.  

Unofficial Earth Flag created by John McConnell includes The Blue Marble photograph taken by the crew of Apollo 17.
Unofficial Earth Flag created by John McConnell includes The Blue Marble photograph taken by the crew of Apollo 17. Via Wikipedia.

A ripple in time: The birth of Earth Day 

In 1970, amidst a growing environmental movement in the United States, Earth Day was created by the junior senator from Wisconsin: Senator Gaylord Nelson.

Public concern about pollution, deforestation and the deterioration of natural habitats was growing but environmental action and protection wasnโ€™t yet on the US national agenda… 

To force the issue, the Senator, along with activist Denis Hayes, envisioned a day dedicated to raising awareness about environmental issues and mobilising communities to take environmental action.

Although originally called the โ€˜Environmental Teach-In’ and aimed university students, the duo quickly realised their concept could inspire a wider audience. They renamed it Earth Day and pencilled it in on the calendar. 

On 22 April 1970, the first Earth Day was celebrated. 

What did the first Earth Day look like?

Looking back at the History of Earth Day: An image of demonstrators in Philadelphia, 1970. It's believed 20 million Americans raised awareness about environmentalism on the first Earth Day. Image shared via Ocean Generation

Itโ€™s reported that 20 million Americans took part in the first Earth Day (around 10% of the total population of the United States at the time).  

They took to the streets, parks and auditoriums to demonstrate against the impacts of 150 years of industrial development.

From coast to coast, US citizens from all walks of life made it clear: They understood and were concerned about the impact we were having on the planet.  

Their voices were heard.  

In July of the same year, President Nixon called for establishment of the EPA: The Environmental Protection Agency. And in the 10 years that followed the first Earth Day, dozens of regulations to protect the environment were put in place in the US.  

President Richard Nixon and First Lady Pat Nixon plant a tree on the White House South Lawn to recognise the world's first Earth Day. Shared by ocean Generation.
President Richard Nixon and First Lady Pat Nixon plant a tree on the White House South Lawn to recognise the world’s first Earth Day.

The origin of Earth Day reminds us that we have immense power to influence political decision making.  

When we care, and make it known we want political action, we let the leaders of our countries know they better want it, too.   

Why Earth Day matters: A call to climate action

By 1990, Earth Day was celebrated by over 140 countries around the globe. Now, Earth Day is the largest civic observance in the world.  

No matter where we live or how old we are, thereโ€™s no denying that looking after our planet is in our best interest.  

The Ocean deserves a VIP invitation to Earth Day celebrations 

If we look down at Earth from space, most of what we see is blue. Over 70% of our planet is Ocean, but more than just big and blue, the Ocean is the beating heart and lungs of our planet.  

The Ocean absorbs 90%
of the excess heat 
associated with climate change.

5 reasons to look after the Ocean this Earth Day  

  • The Ocean is keeping us all alive. It provides over 50% of all oxygen on Earth. Simply put: If the Oceanโ€™s ability to produce oxygen was compromised, weโ€™d be in trouble. 
  • Around 30% of the CO2 we produce is absorbed by the Ocean. 
  • The Ocean helps regulate land temperature and drive global weather patterns. 
  • Coastal โ€œblue carbonโ€ ecosystems, like mangrove forests and seagrass meadows, can sequester (store) more carbon in their soils than terrestrial forests. 
  • The Ocean is the main protein source for over 3 billion people. 

We depend on a healthy Ocean for a healthy planet. In the words of Dr. Sylvia Earle, โ€œNo water, no life. No blue, no green.โ€ 

Whatโ€™s the theme for Earth Day 2024?  

In 2024, the theme for Earth Day is Planet vs. Plastics. 422 million tonnes of plastic are produced annually โ€“ half of which is for single-use purposes.

Plastic is everywhere. It’s in what we wear, the items we use daily, and itโ€™s even in the food we eat. 

We know plastic was designed to be indestructible (so, itโ€™s not going anywhere, anytime soon). We know it has numerous negative impacts on human health. We know single-use plastics are the biggest contributors to marine litter. And we use it anyway.  

Itโ€™s safe to say: We have a problematic relationship with plastic. 

This Earth Day, rethink your relationship with plastic. 

The 2024 theme for Earth Day 
is Planet vs. Plastics.

What action can I take this Earth Day? 

Riding the Wave of Change 

As we commemorate Earth Day, itโ€™s important to reflect on how far weโ€™ve come and re-commit ourselves to leaving our blue planet better than we found it. 

We only have one planet and itโ€™s up to all of us to look after it.  

We only have one planet so we have to look after it.

Citizen science: Monitoring the turtles of the Red Sea

Sea turtle monitoring at the Red Sea, a Wavemaker Story by Serag Heiba. Posted by Ocean Generation, leaders in Ocean education.

The Red Sea is a storied body of water that many have heard of, but few are familiar with.

Its history will bring up names like Hatshepsut and Moses, and its present is fraught with tales of piracy and political unrest.

But thereโ€™s another side to the Red Sea. As the most northern tropical sea, it boasts an incredible biodiversity that makes it both stunningly beautiful and ecologically vital. 

I had the pleasure of spending two weeks with TurtleWatch Egypt 2.0, an organisation dedicated to monitoring the endangered sea turtle populations of Egyptโ€™s Red Sea coast.  

They launched as an initiative in 2011, and registered as an NGO in 2022. I was curious to learn more about marine conservation in my home country. To my luck, TurtleWatch was the perfect place to start.

Based in the small town of Marsa Alam, their day-to-day work may be a dream for many thalassophiles.

Mornings are spent diving in bays rich with seagrass and corals, snapping photos of sea turtles and measuring data like shell length and water temperature.

Of course, their work has less idyllic parts too. Never-ending paperwork, grant applications, and database updates are just as important to the organisationโ€™s functioning.

Thereโ€™s one other thing that makes TurtleWatch especially unique: citizen science.  

They were the first initiative in Egypt aimed at involving divers and snorkelers in marine conservation research.

How? By allowing visitors to the Red Sea to upload their own sightings and pictures of sea turtles, TurtleWatch taps into the potential of everyday people to contribute as citizen scientists.  

These contributions help TurtleWatch identify important feeding and gathering sites for sea turtles, and better understand their movements and short-term migrations. It also helps them assess the impacts people have on these endangered animals.

They use this information to not only improve conservation and protection efforts, but to organise training sessions for dive centres and deliver โ€œturtle talksโ€ to young children, students, and tourists. 

TurtleWatch delivering a turtle talk at a local kindergarten, as explained in a Wavemaker Story published by Ocean Generation, leaders in Ocean education.

Citizen science is not a new concept.

It has been used around the world to classify galaxies and track illegal fishing. But in a place like the Red Sea, which is understudied and where data is insufficient, TurtleWatch has managed to greatly extend their eyes and ears beyond their local vicinity.

Sightings come from all over the coast, and in 2023 they received over 1000 sightings.

It makes perfect sense: Egyptโ€™s Red Sea coast is filled with towns and resorts buzzing with snorkelers and divers, so why not involve them in the effort to protect the very marine life theyโ€™ve come here to enjoy? 

Snorllekers help safeguarding sea turtles with the help of citizen science.

As with everywhere else, the Red Sea hasnโ€™t escaped the destructive impacts of people on the natural world.

Coastal development and tourism are polluting the marine environment and leaving physical scars, while warming waters and acidification are harming the Red Seaโ€™s ability to withstand changes.

The good news is that corals in the Red Sea are some of the most resilient on the planet and could help us protect other corals reefs in the future. 

Coastal development and tourism are polluting marine life in Egypt. Wavemaker Story posted by Ocean Generation.

But before thatโ€™s possible, we will need better regulations and more marine protected areas to safeguard the Red Sea.

Organisations like TurtleWatchโ€”with the aid of citizen scienceโ€”are doing their part to provide much-needed data and help protect this beautiful sea for future generations.

Diving into Kalk Bay: Exploring its past, present, futureย 

My earliest, enduring memory of the Ocean is a stretch of sea rolling away from a vibrant fishing harbour in Kalk Bay, Cape Town.  

The harbourโ€™s position along the False Bay Coast, as well as its rich marine life, played a crucial role in the cityโ€™s early development and prosperity. Little did I know this place would also play an important role in my own life.ย 

Kalk Bay: A link to my childhood and the last connection to my grandmother.

The colourful fishing boats in the harbour that frame the glorious, shimmering stretch of Ocean in my mind like a postcard, idealised to a point far from reality. Today, with names like Star of the Sea and Lucky Strike, those old wooden boats seem struck in a rapidly receding past.

Change has come in great variety and moved with incredible momentum. All aspects of the scene have been altered – from the oceanography and to the social structures and human dimension surrounding the harbour. 

I find it interesting and unsurprising, that when asked to think of a memory about the Ocean, the one I recall is so entangled with the influence of mankind. These two elements – human and Ocean – have been linked for centuries and seem unable to escape one another.

Wavemaker Story by Katie about Kalk Bay, Cape Town's past, present and future.

I feel this tension reflected in the complex and often contradictory nature of our social and ecological aims moving forwards as a society.

Progression too often comes at the high cost of our marine health, a lack of respect for our past and insufficient foresight for our future. All of this points to the difficulty in honouring and preserving our collective pasts whilst building future horizons in sustainable ways.

New strategies for managing the natural environment and its resources should include integrated approaches with new frameworks, stakeholders and communities. 

Kalk Bay as we see it today  

The Kalk Bay area may be reminiscent of the past, but the issues it faces are very much of the present. The harbour is one of the few still in operation, albeit a far cry from its thriving commercial days. Subsistence fishing (the practice of catching fish for personal consumption and not profit) is carried out with a handful of crayfish boats heading out each day. 

With reduced operation has come tourism and commercialisation. You will find restaurants, pop up stalls selling gimmicks, and seals, who emboldened and adjusted to the crowds, sunbathe on the jetty.

Just as the Ocean below has been altered by rising sea levels and an increased frequency of extreme temperature events, so too has the harbour. Unsurprisingly, the advancements and demands of modern life have been the indirect driving forces behind this change.

All the usual culprits – overfishing, climate change, overpopulation, and coastal development- are part of this problem.  Fish stocks caused by overfishing and the violations of size regulations have impacted marine biodiversity and the livelihoods of local fisherman. 

Coastal development have also contributed significantly to these detrimental changes by increasing pollutant runoff and nutrient loading.

This illustrates just how interrelated Ocean and coastal ecosystems are and how integral they are to both human and aquatic life.

Not all hope is lost for Kalk Bay  

Thankfully, thereโ€™s been a growing awareness of and respect for some of these pressing human-made threats, which has led to the establishment of marine protected areas. Currently, 15 % of South Africaโ€™s total marine areas are protected with 1.7 % of this area fully protected.

Evidently, the South African constitution recognises the need for these conservation efforts and acknowledges the responsibility that the fishing and tourism industries have.

Eco-tourism has emerged as a way of protecting and sustainably using the environment, without negatively impacting economic growth and job security.  

A growing awareness in South Africa has led to the establishment of marine protected areas.

We need solutions that engage local communities living in coastal areas. This would encourage the safeguarding of natural resources, improve the quality of peopleโ€™s lives, and potentially assist in building bridges between sections of South African society that has historically been divided.

Approaches such as these work towards achieving a balance between developmental goals and environmental concerns; itโ€™s of course an ongoing process. Therefore, itโ€™s important to thoroughly research and address the priorities and gaps in this area with input from various stakeholders.

Katie, a Wavemaker tells us: My grandmotherโ€™s childhood saw the days when man could still outrun his actions without stopping to catch his breath and consider the implications.

My grandmotherโ€™s childhood saw the days when man could still outrun his actions without stopping to catch his breath and consider any of the implications. The harmony between human and Ocean that existed was only ever on a short-term loan, one with dangerously high interest.

The future seemed as it always does to those on the shores of the present: An island far away.

Katie, a Wavemaker shares this quote: My faith in the [...] next generation of changemakers gives me hope for the future of our marine and coastal ecosystems.

The generation of young people to which I belong to understand that preservation isnโ€™t about merely respecting the present but also about securing the future. Therefore, my faith in the collective creativity and problem-solving abilities of the next generation of changemakers gives me hope for the future of our marine and coastal ecosystems.

The world was our oyster, when the oysters became our world

An experience paving the way for community-led marine conservation. ย 

Like many of us, until recently I had only ever associated oysters with gourmet restaurants and fine dining, an out of reach delicacy plucked from some distant, murky seabed.

After working with oysters, they are now a familiar part of the local marine wildlife, and a hugely important component in the global effort to restore and conserve our Ocean.  

I spent my summer interning with Seawilding, a community-led marine habitat restoration organisation in Scotland. Their mission is to restore seagrass meadows and native oyster reefs, through planting seagrass, growing oysters to form new reefs, and developing successful methods that others can follow, to enable coastal communities across the UK and further afield to take action.

The seascape of Loch Craignishย ย 

Set on the gleaming shores of Loch Craignish, the first time I slipped under the surface was like entering a whole other world.

The salty water enveloped me with an icy embrace, and the seabed materialised below. Vast meadows of seagrass glistened green, with dappled sunlight sparkling through the water column and catching the tails of Goldsinny wrasse and the occasional lonely pipefish.

Snakelock anemones waved like flowers from the grass heads, and red feather stars snaked their arms towards me as I glided past.ย ย 

The fringes of the meadow gave way to soft mudflats, where sparring crabs and dancing prawns entertained passersby. Gobies and flatfish buried themselves in the sand, and large shoals of herring flicked like glassy shards in the distant blue. ย

The oyster reef was by far my favourite; thick layers of oyster shells stacked haphazardly covered the seafloor, carpeted by algae, barnacles and clumps of bladderwrack.

Fish darted in and out of crevices, startled by my shadow, and starfish lay clustered on the rocks, arms splayed as if holding hands. The plethora of animals, and the richness of the life surrounding me was quite literally breathtaking, so much so that I almost choked on the seawater a number of times.

It was inspiring to see so much diversity thriving in Scotlandโ€™s waters.

The work Seawildingโ€™s team has achieved is clearly doing wonders for the wildlife of Loch Craignish, however this is only the tip of the iceberg in the marine conservation and restoration work we need to undertake, not only here in Scotland but across the Ocean.ย ย

The health of the Ocean is essential to us, not only as societies through its cultural significance, but also through its physical services.

Without healthy marine ecosystems, food stability will crumble, coastal erosion will rapidly creep up on communities, and the impacts of climate change will be less cushioned and more sorely felt.ย ย 

Scotlandโ€™s marine wildlife: Then and nowย 

Scotlandโ€™s coasts were once prolific with wildlife. Historic records speak of rivers โ€œoverflowing with salmon, onto the banksโ€, estuaries that had seemingly endless shellfish stocks, and open Ocean brimming with endless shoals of fish.

Oysters were once the food of the poor, and lobster was a common centerpiece at every dinner table. Lush seagrass meadows flanked the shorelines and wildlife flourished, everywhere.ย 

We must start taking Ocean action to prevent further losses. Quote shared by Ocean Generation in an article about marine conservation programmes in the UK.

Now, there are no natural oyster reefs left off Scotlandโ€™s coast, and more than half of the original seagrass meadows have disappeared.

Dredging (removing sediments from the seabed), overfishing, and pollution threaten our coastlines more than ever before, and with the pressures of climate change increasing with each day, we must start taking action to prevent further losses

Seawildingโ€™s work, enthusiasm and passion for the marine environment is a sparkling example of how communities can come together to create real, positive change โ€“ something we should all strive towards.
