Every decision we make has an environmental impact
This means everyone can do something (or more than one something) to make our planet a bluer, healthier place to call home.
Our Ocean plays a critical role in regulating the climate and absorbing carbon emissions – most notably, through blue carbon ecosystems. So, taking Ocean action is in the best interest of all life on Earth.
Ocean action is climate action.
We asked the team at Ocean Generation – from those in our science team; to our founder, Jo Ruxton MBE; to those who manage our youth engagement programmes – to share the ways they take Ocean and climate action each day.
10 daily actions our team of Ocean lovers takes to protect the Ocean:
1) Omit unnecessary car travel
2) Don’t pour cooking oil down the drain
3) The best way to take Ocean action? Educate your inner circle about how important our Ocean is.
Wondering where to start? Incredible Ocean facts for you:
9) Make these easy plastic swaps – and then swear off unnecessary plastic items forever.
At Ocean Generation, we promote an inclusive approach to sustainability. We recognise that zero-waste, plastic-free, vegan, and zero-carbon lifestyles don’t work for everyone – and that’s okay. The world needs all of us to do what we can, within our means.
But in saying that, it’s also important to recognise that too many of us still use single-use plastics too easily. When did you last purchase a plastic bottle, a take-out coffee mug or use a single-use plastic straw?
Most single-use plastic items are unnecessary. There are (excuse the pun) an Ocean of eco-alternatives available.
It’s time to break up with unnecessary plastic. Identify what unnecessary single-use plastic you use. ✅ Make the switch to eco-alternatives. ✅ Commit to never going back. ✅
10) Do your best to take environmental action daily, and accept that ‘your best‘ looks different for everyone.

“What can I do about climate change?”
We’re regularly asked for practical climate actions. Thankfully, there’s a lot we can do to look after our blue planet.
Every decision we make – from what we eat to how we move to the clothes we wear – has an environmental impact. But when faced with fear-mongering headlines and science-backed alarm bells that we’re reaching a climate tipping point, individual actions don’t feel like enough.
Do individual climate actions actually make a difference?
Yes. Think about it: Swapping out your plastic straw for a metal one may not feel like much, but if everyone in Europe did the same, 701 tonnes of plastic could be prevented from entering the environment every year.
Collectively, individual actions are powerful propellers of positive change.
Why should the Ocean have a seat at climate conversations?
The Ocean is a powerful climate change mitigator.
Here’s 3 ways our Ocean mitigates the impacts of climate change:
The Ocean absorbs 90% of excess heat from our climate system, making it an impressive heat sink. In fact, the Ocean is the largest heat sink on Earth.
30% of human-made carbon emissions are absorbed by our Ocean.
The Ocean plays a major role in climate adaption. (Said differently: the Ocean supports our planet’s adjustment to the effects of climate change, for example, through blue carbon ecosystems).
When we take climate action, we are simultaneously taking Ocean action and vice versa.
From reducing your use of single-use plastics to addressing your carbon footprint, there are many effective ways to make a positive difference.
Here are 15 climate actions you can take to restore the Ocean’s health:
1) Skip single-use coffee cups
Many of us start our day with a cup of coffee on the go. It’s a comforting routine that sets the tone for the rest of the day.
If all of Europe made the switch from single-use plastic cups to eco-friendly alternatives, we’d prevent 1,500 tonnes of plastic waste a year.
2) Understand the main 5 human-made threats the Ocean faces
We can’t restore the health of the Ocean if we don’t understand what threatens it.
The UN released a 2,000-page document breaking down the various threats our Ocean faces. Understandably, most people don’t have the time (or desire) to read it. So, we transformed it into 5 easy-to-follow articles about Ocean threats.
Your carbon footprint is the measure of greenhouse gases produced by your daily activities.
This includes things like driving a car, using electricity, the emissions linked to what you wear, and even eating food.
When we understand our carbon footprint, we can shift our behaviours for the better. Here’s an online carbon footprint calculator (we can’t endorse any resource as ‘the most accurate measure of your CO2 footprint’ but this will give you a rough idea of your environmental impact).
It’s important to remember that carbon emission world averages distort the unequal emissions in developed and developing countries. So, it’s helpful to compare your carbon footprint to your national average to assess where you stand.
4) The food on your plate makes an environmental impact
One third of carbon emissions comes from food production.
General tips: Reduce your consumption of high-emission foods like meat and dairy in favour of seasonal fruits and vegetables and snacks that have negative emissions.
5) Put your money where your heart is: Divest from fossil fuels
Are your monetary investments benefiting the planet? Divesting from fossil fuels means taking your money out of the hands of the fossil fuel industry, which contributes significantly to carbon emissions and climate change.
You can start by checking your bank and investment accounts and moving your money to institutions that don’t invest in fossil fuels. Even small divestments make a difference.
6) Avoid products with microbeads
Microbeads are small plastic beads often found in beauty and personal care products. These tiny pieces of plastic easily slip down our drains, through water treatment plants and into the Ocean.
Most of us purchase products – facial scrubs, toothpaste, nail polish, and abrasive household cleaning products – without realising they contain microbeads.
Quick solution to the microbead problem: Check ingredient lists and front labels. Microbeads and polyethylene are often listed on packaging, making them easy to avoid.
7) Think before you toss your clothes into the laundry
Every time we do an average laundry load of 6kg, 700,000 fibres can be released into our waterways. Before you put something in the washing basket, consider if it can first be worn again.
Take this a step further by investing in a bag built to capture micro-fibres and choosing sustainable clothing materials when it’s time to purchasing something.
8) Conserve water
Only 0.5% of water on Earth is useable and available as freshwater. So, we’re not joking when we say water is liquid gold.
It’s a key prerequisite for human development and, already, a quarter of all cities are water stressed. Little actions add up: Cringe when you see a character in a movie running water for ages; make sure you turn your tap off while brushing your teeth; install a waster-wise shower-head; fix those leaks.
You may feel that your climate action a drop in the Ocean – but the Ocean would be less without that drop.
Every drop counts.
9) Understand the impact of fast fashion on the environment
Fast fashion is responsible for 8 – 10% of global carbon emissions (which is more than all international flights and maritime shipping – combined).
Outfit repeating, sustainable fabrics, shopping second-hand and only purchasing items you know you’ll re-wear over and over again are in fashion this season. Scroll: How to take the fast out of fast fashion.
10) What’s the impact of how you travel?
No one’s surprised to learn: Flying is one of the most carbon-intensive modes of transportation. But did you know that flying at night is actually worse for the planet than flying during the day? Now you do.
Walking and cycling are both climate-friendly and positively impact our health (who doesn’t love a hot girl walk?).
Suggestions when it comes to catching flights:
Where alternatives exist, don’t fly.
When you need to fly, choose direct flights to maximise fuel efficiency and minimise emissions associated with take-offs.
11) Plant a mangrove tree – with the click of a button – to take Ocean action
By planting a mangrove tree, you’re making a direct impact on the environment. Plant (follow).
12) Rethink your relationship with plastic
You knew it was coming. It wouldn’t be a climate change actions list without mention of plastic.
Plastic is everywhere – from the clothing you’re wearing to the spot you’re sitting right now and even in the food we eat. There’s no getting rid of a material designed to last forever, but reducing our consumption of single-use plastics is essential for a healthy Ocean and planet.
Start by rethinking your relationship with plastic. Instead of leaning on recycling, start reusing, reducing, totally refusing plastic options where you can.
13) Start saying ‘Ocean’ not oceans
At school, we’re all taught about the Ocean having 5 regions, but our Ocean isn’t separated by borders. It’s one, connected system.
What happens in one part of the Ocean impacts Ocean health as a whole.
If we all understood this, we’d be more mindful of what we dump in the Ocean, what we take out of it, and how we use it daily. As you go about your life, start saying Ocean – big O, no s. Not only does it highlight the interconnectedness of the Ocean, but also how our daily actions impact it.
14) Be a voice for our Ocean
The Ocean is quite literally keeping us alive. It’s our planet’s life support system, but most people don’t realise that.
By keeping yourself informed about the importance of the Ocean, the human-made threats it faces, and the various actions we can take to protect it – and then sharing that Ocean intelligence, you can propel a wave of positive change for our planet.
Sign up to our newsletter for monthly Ocean education. Submit a Wavemaker Story to let your voice for the Ocean be amplified on our channels. Share educational posts you come across. Be an Ocean advocate – not just on World Ocean Day but every day.
15) Accept that you can’t do everything. Start where you are.
It’s important to acknowledge that no one can do it all when it comes to tackling climate change and restoring the Ocean’s health.
Striving to be a perfect environmentalist often leads to eco-anxiety and feelings of defeat about the amount of work to be done. The reality is: Imperfection is still helpful, and it’s a lot more inclusive than unrealistic demands for perfection.
Our blue planet doesn’t need a handful of perfect environmentalists. Earth needs millions of imperfect people doing what they can to make a difference, and always trying to do better.
Embrace imperfect environmentalism with us by starting where you are. Commit to one – or several – of these items right now. Collectively, we can make waves.
What we Eat: Is locally sourced food better for the planet?
Share this page
Copied
Over 10,000 years ago, we planted our first seeds and domesticated animals – marking a major milestone for homo sapiens (humans).
Fast forward to the present and it’s easy to see that we’ve come a long way from founding agricultural practices to the complex globalised food system we’ve built today.
Many of us are now able to purchase foods, in and out of season, throughout the year. Food systems tend to be high-yielding and complex: the low cost of the products could be argued to be offset by the hefty environmental cost.
Is eating locally sourced food better for the planet?
We are exploring the public discourse between local and non-local foods, through the lens of carbon emissions.
But first, we need to understand the components of the food system.
What’s the environmental cost of the food on my plate?
The food on our plates often makes its way to us through a complex food system.
What is a food system?
A food system refers to the entire process (aka lifecycle) of producing, processing, distributing and consuming food.
This system accounts for a third, or 18 GTCO2eq, of all greenhouse gas (GHG) emissions where:
– Agricultural production (farms and animal feed) is responsible for a whopping 39% of the emissions.
– Changes in land use (deforestation and fluctuations in carbon in soil) is responsible for 32% of the emissions and,
– Other supply chain activities (like processing, transport, retail, packaging, and consumption) are responsible for 29% of the emissions.
Aside from emissions, food systems are also accountable for high water usage and being the primary driver of biodiversity loss.
Evidently, the systems we’ve built need transformative changes that minimise this environmental toll. It also means addressing the undeniable role of the meat and dairy industry in the rise of emissions.
From a consumer perspective, many argue that buying local produce is the best way to minimise our emissions.
Although this is a popular policy recommendation, academia suggests a slightly different picture.
What does “locally sourced” food mean?
There is no widely accepted definition of ‘local’ food, but it broadly revolves around minimal distances between where the food is produced and where it is consumed.
– Within a community, city, village, or county, – Within a State (like in US, India), or, – Within a small country (like Jamaica, Estonia, Lebanon)
In the US, according to the 2008 Farm Act, to be classified as ‘local’, foods would have to come from 400 miles or less.
If we apply this to a person shopping in Slovenia, a small European country, they could, in theory, buy produce from all their neighbouring countries and consider that as ‘local’.
So, the different interpretations to ‘local’ food allows room for varying circumstances.
Does the type of transport used for foods matter?
Yes! It is worth noting the emission disparities between different modes of transport.
The most GHG-efficient option for transporting food is via cargo ships. This is followed by rail, cars, vans, and trucks.
Unintuitively, storing foods locally year-round tend to be more GHG intensive than having the same products shipped from another country.
In general, air freighted foods are the least GHG-efficient. As a consumer, it can be difficult to assess what is air-freighted and what is not.
A useful guide is to assess whether the product has a limited shelf life (for example, mangoes and berries) and if it is from a country quite far away.
Now, let’s dive into a common question encountered in the local vs non-local food debate.
Don’t non-locally sourced foods mean higher travel emissions?
Not necessarily.
Here are eight foods and their supply chain emissions visualised in two ways:
Figure 1 GHG Emissions across the supply chain [Credit: Our World in Data]Figure 2 Relative GHG Emissions across the supply chain [Credit: Our World in Data]
In figure 1, we are able to see the overall emissions of certain foods, noting that some foods have high emissions (like meat) while some have low or negative emissions (like nuts). Therefore, we can make the biggest impact by swapping out high-emission foods where possible.
Figure 2 allows for a deeper understanding of emissions from each step of the supply chain. Although there are exceptions, travel emissions for most foods are minimal compared to the emissions associated with land use, farming, and animal feed.
If you’d like to learn more about this in the context of other foods, click here to use the graphing tool.
What are the best practices to adopt when sourcing foods?
From an environmental perspective, making decisions on how to source foods can be unclear.
Some of the best practices guided by growing evidence suggests the following:
– In terms of emissions reduction, what you eat matters more than whether it is local or not.
– In general, buy locally grown seasonal foods like vegetables and fruits.
– Buy local especially if you know where you’re buying from, who you’re buying from and how they grow the food. The transparency of supply chains will enable you to consider wider environmental, economic, and social impacts to make well-informed decisions.
Mangroves are the only forests situated at the confluence of land and sea in the world’s subtropics and tropics. They have been variously described as “coastal woodland”, “mangal”, “tidal forest” and “mangrove forest.”
There are roughly 70 species of mangrove trees occupying a total estimated area of 147,000 km2 worldwide. This is equivalent to the size of Bangladesh! Roughly 43% of the world’s mangrove forests are situated in just four countries: Indonesia, Australia, Brazil, and Nigeria.
These forests are home to an abundance of life, protecting people from floods whilst storing carbon at an impressive capacity.
Biodiversity in mangrove forests
In the right conditions, mangroves form extensive and productive forests.
These forests support animal populations both within the forest and in offshore areas. Densities of crabs are especially likely to be highest on unvegetated mudbanks adjacent to mangroves, feeding on propagules (buds of plants).
Juvenile shrimps are important organisms near mangroves too, and a sought-after food for many communities. These shrimps obtain carbon (food) from plankton and algae living amongst the mangroves.
There are also a few endemic mammal species in mangroves. For example, crab-eating rats in Australia, the leaf monkey in Malaysia, and the proboscis monkey in Borneo.
Here is a diagram further highlighting the importance of mangroves to so many species for different reasons –
Figure 1 Conceptual diagram illustrating the critical habitat that mangroves provide for a variety of animals [Credit: Integration and Application Network, University of Maryland Center for Environmental Science]
Why should we care about mangrove trees?
– Mangrove forests are widely recognised as providing a wide variety of goods and services to people, including protection from floods, provision of a variety of plant and animal products, sediment trapping, and nutrient uptake and transformation.
– Annually, mangroves are responsible for over $60 billion in avoided losses from coastal flooding, protecting more than 15 million people.
– An impressive diversity of plant products is harvested from mangrove trees, including tannins, honey, medicinal products, and thatch.
Mangroves are a blue carbon solution
– Mangroves have gained a lot of attention in recent years over their ability to sequester carbon, storing between 3-5 timesmore carbon per hectare than terrestrial forests.
– They have carbon-rich soil that’s been built-up for over hundreds or thousands of years.
– 87% of carbon stocks in mangroves are just within the top meter of soil. According to one report, if this were released into the atmosphere, it would be equal to 7.5 years of emissions from the EU or burning 51 billion barrels of oil.
What are the drivers of degradation and loss of mangroves?
Up to 60% of mangrove tree losses are due to direct or indirect human impacts. These drivers are –
– Logging (for timber, charcoal) – Agriculture (oil palm cultivation) – Aquaculture (ponds for shrimp and fish farming) – Pollution (from oil and gas extraction, and nutrient run-off) – Coastal infrastructure development – Climate change (sea level rise, hurricanes, drought)
Mangrove Restoration and Conservation Efforts
Our knowledge of mangrove area dynamics at local to global scales has increased significantly since 2000 due to advances in remote sensing and data access.
Around 42% of remaining mangroves are now located in protected areas. But protected areas may not always provide strong protection. Many mangroves fall prey to erosion and storms, naturally occurring phenomena, while some don’t stand the test of time due to ineffective management.
The front line of mangrove protection, management and sustainable use involves people—communities, indigenous groups, traditional users, and local governments.
The Global Mangrove Alliance, is an important and ambitious initiative, seeking to halt loss caused by direct human impact, restore at least half of recent mangrove losses, and increase protection from over 40% to 80% by 2030.
How coastal communities have helped mangrove forests thrive
Around the world, there are countless examples of collaborations that have helped coastal communities and mangroves to thrive together.
For example, in Pakistan, mangroves are concentrated mainly in the north along the Arabian Sea coastline where arid climate prevails. Under the Ten Billion Tree Tsunami Project, 43.50 million plants will be planted in one of the world’s largest endeavours to restore mangroves.
This ambitious project will not only provide a natural barrier against erosion, climate disasters but will also restore breeding grounds for finfish and shrimps. It has the potential to improve the livelihoods of fishing and herding communities living in the many coastal villages dotting the country’s northern shores.
Mangrove planting has been increasingly considered a Nature-based Solution (NbS)
This enthusiasm, seen through national policy commitments and community-led initiatives, can now be assessed against a Global Standard for NbS, a criteria set by the International Union for Conservation of Nature (IUCN) to ensure that these projects are credible and well-designed to maximise their full potential.
Mangroves provide many benefits and their ability to store carbon cannot be ignored. It is a useful nature-based solution to help reduce our emissions but it’s not the only one!
What can I do to further mangrove conservation?
Show your support for mangroves in native areas – Find out if mangroves are native to your surroundings. If they are, vocalise your support for them and educate your community on the importance of mangroves.
If your local mangroves are subject to degradation, rally support for preservation and speak to your local authorities.You can also keep track of mangrove restoration through the Mangrove Restoration Tracker tool.
Be a considerate tourist – Mangrove tourism exists across 93 countries, with boating being the most popular activity. So next time you travel, appreciate mangroves and the diverse wildlife they host but don’t leave anything behind!
You can also participate in mangrove planting, for example, in the Philippines, through the Planeterra Project.
What is the UN High Seas Treaty and why does it matter?
Share this page
Copied
After two decades, the open Ocean or ‘high seas’ are on its way to being protected.
On 20th February 2023, the fifth session of the Intergovernmental Conference (IGC) on Conservation and Sustainable Use of Marine Biodiversity of Areas Beyond National Jurisdiction (BBNJ) resumed negotiations in attempt to agree on a treaty to protect the high seas.
The last negotiations were held in August 2022 and ended without agreement.
“Our Ocean has been under pressure for decades and we cannot ignore the Ocean emergency,” said António Guterres, UN Secretary-General in a statement, reiterating the need for a treaty that paves the way for a sustainable Ocean.
What are the “high seas”?
High seas refer to the vast majority of the Ocean that lies beyond national jurisdictions. This open water is not governed by any one country and covers 64% of the Ocean’s surface.

What does the High Seas Treaty mean for our Ocean?
After an extra day of intense negotiations, IGC president, Rena Lee, Singapore, announced that the United Nations (UN) High Seas Treaty had been agreed.
This was a monumental milestone twenty years in the making.

“The ship has reached the shore!”
IGC President, Rena Lee, Singapore.
5 main takeaways from the High Seas Treaty:
Strengthening 30 x 30 –
This agreement seeks to protect 30% of the Ocean by 2030. This was an outcome from COP 15 (the global biodiversity conference held in Dec, 2022) that will be strengthened with the help of this treaty.
Marine Protected Areas (MPA’s) –
This treaty will provide the legal framework necessary to set up MPA’s as no such framework currently exists.
Conference of the Parties (COP) –
Establish a COP to ensure accountability on issues like biodiversity and governance.
Marine Genetic Resources (MGR’s) –
Highlighting the need for processes to share genetic resources like plants and animals for pharmaceuticals, food, cosmetics, etc.
Environmental Impact Assessments (EIA’s) –
Greater obligations to conduct EIA’s on activities relating to pollution or any potential effects on the marine environment that is unknown or not yet fully understood.
Ocean Generation’s Statement on the High Seas Treaty:
“We are delighted to hear that the UN High Seas Treaty has finally become a reality.
A healthy Ocean is vital for the survival of all living things, and this is the message we continue to deliver through our work at Ocean Generation. Protecting 30% by 2030 must, however, be seen as a minimum requirement.
We view this agreement as a starting point. The Ocean is our ally in the fight against climate change and we must stop underestimating its role in our survival. The sooner this treaty is ratified by all countries, the better chance we have of a safe and healthy future for the generations that will follow us.”
Jo Ruxton MBE Founder of Ocean Generation
We intend to update this article once the final text of the treaty has been published.
The Ocean stores a considerable amount of our carbon:
The Ocean is one of the largest natural carbon sinks on Earth, making it a crucial component of the carbon cycle. This means that the Ocean captures carbon dioxide from the atmosphere.
This carbon is stored in surface waters, eventually making its way into the deep Ocean.
But there are other ways in which carbon is stored…
The role of blue carbon
All along our coastlines, we have unique ecosystems that capture and lock carbon away, mostly in the soil, for sometimes thousands of years.
– coastal protection (acting as a buffer between the Ocean and land) – increased biodiversity – reducing Ocean acidification – soil stabilisation – improved water flow and water quality – storm and flooding surge prevention, and – increased resilience to cyclones
These ecosystems can be considered a nature-based solution in tackling the rise the carbon emissions.
But they are under threat. In fact, globally, between 20-50% of blue carbon ecosystems have already been converted or degraded.
Drivers of blue carbon loss and degradation
Our coastlines are often competed for – whether its daily Ocean activities or commercial purposes.
This invariably devalues existing blue carbon ecosystems. The main drivers of loss and degradation are:
The case for protection and restoration of blue carbon ecosystems
If degraded or lost, blue carbon ecosystems have the potential to release the carbon back into the atmosphere.
This is not the best scenario, given carbon dioxide levels in the atmosphere are already reaching levels not experienced in at least 2 million years (!).
Not only is protection and restoration good for the climate, but it also has the potential to create jobs and support economic growth.
Coastal ecosystems have the ability to mitigate around 0.5-2% of current global emissions. However, there is high uncertainty around its potential in the face of future climate scenarios, as well as loss of coastal land due to sea level rise.
Many restoration efforts have failed in the past, mainly due to not addressing the root causes of degradation.
It is now understood that successful restoration efforts require local communities’ involvement at every stage, economic incentives, and robust frameworks for implementing and assessing these ecosystems.
Most importantly, reducing human activities in these areas can aid the recovery of these precious ecosystems.
We need existing solutions to work together to reduce the adverse effects of the climate crisis.
We must protect what we have, restore what we have lost, and adapt to the circumstances we face.
Seagrasses are among the most widespread coastal ecosystems worldwide and range from the tropics to boreal margins of the Ocean.
They are flowering plants that live in shallow waters that can sometimes be seen from space.
The name seagrass stems from the many species with long and narrow leaves, which grow by rhizome extension and often spread across large “meadows” resembling grassland; many species superficially resemble terrestrial grasses.
These deep-rooted meadows cover over 300,000km2, roughly the size of Italy, spanning 159 countries and six continents. They do not exist in Antarctica.
Sometimes referred to as ‘lungs of the sea’, seagrasses play a multi-functional role to both human well-being and marine life, while being a globally significant carbon sink.
Seagrasses are a climate change solution
According to UNEP, despite occupying just 0.1% of the Ocean floor, seagrasses store up to 18% of the global Oceanic carbon, which is estimated to be 38,000 billion metric tons.
What’s more:
– They can store twice the amount of carbon per hectare when compared to terrestrial forests.
– The carbon is stored almost entirely in the soils, measuring up to four metres deep.
– They can act as a buffer for Ocean acidification, depending on environmental conditions, which benefits calcifying organisms like corals and shellfish.
But that’s not all!
How seagrasses support marine life
Seagrasses are biologically rich and diverse habitats where species come together for many reasons.
Some organisms – primarily large grazers like manatees, dugongs, green sea turtles and geese – eat the living leaves directly, and seagrass forms a major component of their diets.
For example, an adult dugong eats about 64 to 88 pounds (28 to 40 kg) of seagrass a day, while an adult green sea turtle can eat about 4.5 pounds (2 kg) per day.
Apart from being a food source, seagrass meadows provide protection for burrowing anemones, bivalve molluscs and burrowing urchins that lie buried in the sand beneath.
They also act as crucial nursery grounds for species like the European eel. It is estimated that 17 species of coral reef fish spend their entire juvenile life stage solely on seagrass flats.
Four ways seagrass meadows benefit humans
There are numerous ways in which seagrasses benefit us outside of their climate change mitigation potential. Benefits include:
– Food Security – They support global fisheries, acting as nursery habitats for commonly consumed species like crustaceans and molluscs.
– Coastal Protection – Seagrasses have an extensive root system that stabilises the sea bed, similar to terrestrial grasses preventing soil erosion. In this way, they protect coastlines from flooding and storm surges.
– Tourism – Whether its swimming with green turtles (Akumal, Mexico) or diving with dugongs (Marsa Alam, Egypt), seagrass meadows are a great place to positively interact with the diverse marine life it hosts.
They are also important for historical heritage, from shipwrecks to submerged ancient cities.
– Disease Control – Seagrasses can control diseases by reducing bacterial pathogens from harming humans, fish, and invertebrates.
Why are seagrasses threatened?
According to one report, since 1990, there is a 7% decline in seagrass cover area globally per year, which is equivalent to a football field of seagrass every 30 minutes.
The main threats to seagrasses are:
– Climate Change (for example, heat stress through increases in temperature) – Pollution (urban, industrial, and agricultural run-off) – Coastal Infrastructure Development (incl. dredging) – Overfishing (incl. bottom trawling), and – Boating Activities
…but all hope is not lost!
The role of policy is a crucial top-down approach to restore and protect seagrasses at a broader scale.
With the widely accepted Global Biodiversity Framework, 30% of coastal and marine ecosystems need to be protected, including blue carbon ecosystems like seagrasses. Although, at present, mangroves and coral reefs are better protected under MPA’s than seagrasses.
The variety of ecosystem services that seagrasses provide has resulted in increasing knowledge of their value in recent years. However, there are still large knowledge gaps among the general public.
The best way to protect seagrasses is to understand them within local environments and manage threats effectively.
Restoration Spotlight: Seagrasses in the Eastern Shore of Virginia
The Virginia Institute of Marine Science and The Nature Conservancy have been conducting an extensive seagrass meadow restoration for almost 20 years, creating 3,612 hectares of new seagrass beds.
To achieve that, the team of researchers and volunteers had to actively plant more than 70 million seeds of eelgrass on a 200-hectare plot just off the southern end of Virginia’s Eastern Shore.
Within 10 years, the seagrasses covered an area that would naturally take over 100 years to grow. The scientists also noted increased water quality, nitrogen storage and carbon sequestration.
This initiative offers a glimpse into the benefits of resilient seagrass meadows and its importance in addressing climate change.
“Seagrasses can help us solve our biggest environmental challenges.
They purify water, they protect us from storms, they provide food to hundreds of millions of people, they support rich biodiversity, and they efficiently store carbon.
In light of everything seagrasses do for people and nature, protecting and restoring them is vital.”
Ronald Jumeau Permanent Representative to the United Nations and Ambassador for Climate Change Republic of Seychelles
What can I do to help protect seagrasses?
Be a considerate tourist –
Exploring tourist-friendly seagrass meadows can be a great way to develop an appreciation for these wonderful plants and all that they hold. But please don’t pluck them or hurt any marine species when visiting.
Become a citizen scientist –
Furthering scientific knowledge is not a one-person effort and so, public participation in citizen science projects are a fantastic way to contribute.
The SeagrassSpotter project has been created by Project Seagrass in association with Cardiff University and Swansea University. Using SeagrassSpotter, you can help locate seagrasses which will be used by scientists for research including the prediction of locations for restoration.
The fashion industry pushes the idea that more is better — more trends, more products, more shopping; but who benefits from this? Certainly not consumers who feel the pressure to constantly stay on trend, or the environment struggling to keep up with the growing landfills and increased plastic count in our Ocean.
So, how do we break free from this craze? We slow down.
A mindful approach to fashion
What is “slow fashion”?
Slow fashion is a mindful look at clothing from environmental factors to health implications and ethical working conditions for those that make the clothing. It is bringing fashion in harmony with our world.
Five simple ways to transition from fast fashion to a slow fashion wardrobe
When selecting new pieces of clothing, look for products made out of fibers such as cotton or linen .
Many times, brands will claim their items are natural, but in fact are mostly synthetic with only a small percentage of natural fibers.
The tag on the inside of the item is the place to go to confirm what the fabric is made of — think of it as the garment’s ingredient label. Choose pieces that are a majority natural — the closer to 100% the better!
In addition to fabric type, look for GOTS (Global Organic Textile Standard), OEKO–TEX®, and bluesign® certifications to be sure that the all-natural clothing is truly organic and not processed with toxic chemicals and dyes.
How to choose clothing created in ethical working environments:
Beyond fabric composition, there are certifications indicative of a sustainable brand.
Fairtrade certified brands follow criteria that create ethical working environments for farmers and garment workers, support eco-friendly practices and prioritise fair pay.
B Corporations adhere to levels of transparency, ensure ethical employee treatment and charitable giving, and demonstrate positive environmental impacts. Look for these when shopping to support brands that support their workers and the environment.
Building a sustainable wardrobe starts with investing in quality pieces for everyday wear based on your style, known as a capsule wardrobe.
Think of the 3–5 items that you wear most often and feel the best in. Then, invest in all-natural items that will complement the staples you already own.
The goal is to have a closet that can be paired countless ways without having to own a lot of clothing.
4. Buy less, wear more
This brings us to the mantra, buy less, wear more. When you need to shop for something new, ask yourself these questions:
Will this pair well with what I already own?
Will I wear this for more than just one occasion?
Sometimes an outfit is specific to an event, such as a party, graduation, or a wedding. But, if more often than not you are making the most of your wardrobe, then you are participating in this more mindful approach to fashion.
When you feel that an item no longer fits in your wardrobe but is still in good shape, donating to a shelter is a great option.
Many brands offer buy-back programs where you can send back your pre-loved item from their brand, and they will recycle it properly for you.
Try thrifting or renting wardrobe items
Thrifting and renting clothing have become popular options, thrifting for its lower cost point and unique finds, and renting for when you need an outfit for a specific occasion.
Do your friends also have clothes they are bored with? Hold a clothes swap where you each bring a few pieces and trade off.
There are endless ways to extend the lifetime of clothing and bring mindfulness into fashion – which all contribute to better caring for our Ocean and planet. Have fun with it!

Along the fringes of coastlines, where land and Ocean meet, grow the world’s mighty mangrove trees.
These resilient trees grow along shorelines, with their complex root networks stretching deep into the mud. These coastal ecosystems are found on every continent except Antartica.
Although mangroves may not look like much, they have unique adaptations that allow them to live in saltwater environments and provide crucial habitats for many marine species.
Why are mangrove trees an Ocean solution?
Mangrove ecosystems are a potent, nature-based solution tackling Ocean threats like climate change and loss of biodiversity.
They are the only forests situated at the confluence of land and sea in the world’s subtropics and tropics and are often called “coastal woodlands”, “tidal forests” and “mangrove forests.”
So, what makes mangroves a climate solution?
Here are 5 ways mangroves trees tackle climate change:
Mangroves are carbon sinks
Mangrove trees are highly effective carbon sinks. They sequester (the process of removing carbon from the atmosphere) 3 – 5 times more carbon per hectare than rainforests and they store up to 5 times more carbon per equivalent area.
Carbon stored in mangrove forests is considered blue carbon as it’s stored on the coast.
“The soil of mangrove forests alone can hold more than two years of global emissions – that’s 22 billion tons of carbon,” according to Project Drawdown. This is why they are a huge Climate Action solution!
Mangrove forests are biodiversity hotspots
There are up to 25 more species of fish and other wildlife in mangroves than in areas where they have been cut down.
Mangroves also provide nesting and breeding habitats for fish and shellfish, birds and sea turtles.
How do mangrove trees improve food security?
For people living in coastal regions, healthy mangrove forests provide a healthy ecosystem from which to fish – and healthy farmland from which to grow crops and other produce.
Mangroves are storm protectors
Mangroves act as natural protection for coastal communities as they protect them from increased storm surges, flooding and hurricanes.
Your coastal water quality ensurer
The heavy network of mangrove roots helps filter sediments, heavy metals and other pollutants. This prevents the contamination of waterways and preserves delicate habitats like coral reefs and seagrass beds.
We’re losing mangrove forests at an alarming rate
Mangroves are some of the world’s most valuable coastal ecosystems and yet we’ve lost around 50% of Earth’s mangroves in the past 50 years alone.
If this trajectory continues, we could lose all mangroves within the next 100 years.
By destroying mangrove habitats we not only take away a source of carbon sequestration, we also release all the carbon stored back into the atmosphere.
Take climate action: Plant a mangrove
At Ocean Generation, we recognise the that planting mangrove trees is a simple and effective step to take Ocean action – and it’s accessible to everyone.
Introducing: The Mangrove Mandate
We’re partnering with local experts to restore mangrove forests in Madagascar. Not only does it give you a chance to take Ocean action at the click of a button but it embodies the way we see the Ocean: as part of the solution; not a victim to the world’s problems.
The Ocean is a vital life-support system to all life on Earth
Everything that we rely on in our day to day lives – from our water, food, and every second breath – leads back to the Ocean.
Somewhere along the way, we’ve become disconnected from our blue planet.
Why is our Ocean so important?
If we were in space and looked down at Earth, we would mostly see the colour blue.
Our Ocean covers over 70% of the planet, which is why we call it our Blue Planet. It produces over 50% of the oxygen we breathe; meaning that every second breathe we take comes from the Ocean.
Our Ocean helps regulate the temperature on land and is responsible for global weather patterns like storms and heatwaves (which we’ve been seeing more of in the recent years).
It absorbs the sun’s heat, transferring it to the atmosphere and distributing it around the world – warming in the winter and cooling in the summer. Our Ocean is a key driver of how our world functions and yet it’s usually low down on governments agendas.
How many of these Ocean facts do you know?
Containing roughly 97% of the world’s water, our Ocean supports all life on Earth.
It is home to thousands of plants and organisms. And yet, scientists estimate that 91% of species are still to be discovered. Should we stop looking for aliens on Mars and start looking for our own E.T in the Ocean?
From the oldest species in the entire world to the largest living animal in the world – the blue whale – the Ocean’s biodiversity is astonishing.
With only roughly 5% of the Ocean explored until now, we are only just beginning to scratch the surface of the mystical world that exists below the surface of our deep blue sea.
For all of our reliance on the Ocean, a majority of it is a vast, underwater realm that remains unmapped, unobserved, and unexplored. It’s time to unlock more of the Ocean’s secrets.
How the Ocean supports all life
Our Ocean provides us with food and facilitates pleasure, as well as livelihoods for millions, if not billions of people.
But it’s not just a commodity. The Ocean is restorative. It calms and connects us. The positive impact it can have on our wellbeing is incredible.
As humans, we depend on the Ocean for a huge part of the oxygen, water and food we need to survive.
Did you know that 17% of animal protein that is eaten around the world comes from the Ocean?
To this day, many people’s jobs rely on fishing and water-based transport. The Ocean is a crucial component of entire global economies.
5 ways the Ocean helps our wellbeing:
The movement of gentle Ocean waves and fish in an aquarium is known as Heraclitean Motion. These peaceful, repetitive movements are psychologically calming.
Studies have shown that people perceive nature as a positive, and spending time amongst it is known to improve mood.
Various studies have shown improved mental and physical health in those who spend time near the coast.
When swimming, breathing patterns affect the brain and increase positive hormones.
The sounds of waves support meditation techniques.
So, why are so many of us so disconnected from the Ocean?
Do you think of the Ocean as something you only see while on holiday? Or perhaps you live in a city or town, so you feel it’s too far away for you to feel connected to it?
You may be shocked to know, 1 out of every 2 people in the world live near coastal areas.
And because the Ocean provides every second breath, the Ocean has an impact on our lives no matter where we live. Our actions have an impact on the Ocean too.
Did you know that there is now new water made on Earth? The same water cycles around. This water cycle is a closed loop that has existed for billions of years.
We are deeply connected to this global water body, influencing our everyday lives in so many ways, like every single thing we eat, breathe and drink.
Without a healthy Ocean, we will not have a healthy future.
We all need to understand how important the Ocean is to our daily lives to be continually motivated to protect it.
