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

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

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 Craignish  

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.  

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.

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 Scotland’s waters.

The work Seawilding’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.

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.  

Scotland’s marine wildlife: Then and now 

Scotland’s coasts were once prolific with wildlife. Historic records speak of rivers “overflowing with salmon, onto the banks”, 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. 

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 Scotland’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

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

Why is the Ocean so important?

Ocean wave crashing on a rock. Shared by Ocean Generation in an article about why the Ocean is important.

Introducing the Ocean: Our most precious, life-giving, climateregulating, yet recklessly exploited, undervalued, and underfunded resource.  

Covering over 70% of our blue planet and holding roughly 97% of the world’s water, the Ocean provides the foundation for all living things. From the smallest plankton to the largest animal to have ever lived (the blue whale). And that’s just the beginning of why the Ocean is important.

Energy is cycled across its single, interconnected system; keeping everything in balance. It allows all life to exist together in harmony. 

The Ocean makes up over 90% of all habitable space on Earth.  

Just think about that. All the rainforests, grasslands, mountain ranges and deserts combined with every town, city and village of human civilisation make up less than 10% of the liveable space on our planet.  

Everything else is Ocean.  

The Ocean exists on a scale beyond our understanding. ocean facts shared by Ocean Generation: Experts in Ocean health.

An Ocean which is home to the world’s largest mountain range (the Mid Ocean Ridge is over seven times longer than the Andes).

And the world’s deepest canyon. (Challenger Deep is six times deeper than the Grand Canyon and could easily swallow Mount Everest.) 

This vast, interconnected body of water exists on a scale so large that it’s almost beyond the realm of our understanding. 

But we need to understand why the Ocean is important.  

The Ocean defines our planet and provides the very foundation of our existence 

If it could talk, the Ocean would be able to tell us all about the dinosaurs, the ice age, and how Stonehenge or Egypt’s pyramids were really built. The Ocean watched as the earliest Homo Sapiens (that’s us) took our first footsteps. It may even hold the secrets to the very beginning of life on Earth.  

Two circle images beside each other: One of the pyramids in Egypt and another of a calm Ocean scene. Ocean Generation is sharing why the Ocean is so important in this article.

To look back at the history of the Ocean is to look back at the history of life itself.  

For millions of years, the Ocean has provided the conditions required for the evolution of all living things. The Ocean burst into life during the Cambrian explosion (the *relatively* sudden radiation and divergence of complex life forms) around 538.8 million years ago and has seen all five mass extinction events since. 

Make that six.  

At this very moment, we are living through the sixth mass extinction event. Research shows that species are now going extinct between 100 and 1,000 times faster than natural, background extinction rates.  

The delicate balance of life which has been slowly ticking along for millions of years has taken decades to unravel.  

According to the IUCN Red List, over 44,000 assessed species are threatened with extinction.  

It’s almost impossible to comprehend that we are hurtling towards destruction on a scale comparable to that caused by a colossal asteroid collision 66 million years ago. (That, the last mass extinction event, wiped out the dinosaurs).   

Except this time, humanity are both the asteroid and the dinosaurs.

Is the Ocean too vast to feel our impact?  

People used to think the Ocean existed on such an infinite, untouchable scale that nothing we, people, could do would affect its limitless bounty.  

“Man marks the earth with ruin – his control stops with the shore…”

– Lord Byron, Nineteenth Century.

We now know that this is wrong.  

Throughout the last decades, our Ocean has been heating up. It’s becoming more acidic, choking in plastic, drained of its fish stocks, and pumped with toxic chemicals at a rate far beyond which it can sustain.  

We have borne witness to record breaking temperatures, mass coral-bleaching and glacial melting events. Now, we are hurtling towards a ‘new normal’ in which instability and volatility are centre stage. 

We have been recklessly exploiting our Ocean system.  

We have watched as records are broken time and time again.  

But in 2023, the Ocean temperature record wasn’t just broken, it was absolutely obliterated. 

In fact, the entire upper 2000m of the Ocean experienced shatteringly high temperatures. As this surface layer heats up, it’s less able to mix with deep water below. As a result, surface oxygen content has decreased.  

Image of a glacier in the Ocean with the quote: In 2023, the Ocean temperature record wasn’t just broken, it was absolutely obliterated.

This isn’t only detrimental to marine ecosystems, but it also slows the Ocean’s life-saving ability to sequester (remove and store) atmospheric carbon dioxide.  

The global water cycle has also been amplified by our warming Ocean. For us on land, this means stronger, longer droughts as well as intensified rainfall, storm, and flooding events.  

Restoring the Ocean starts on land – with us.

Just like how people once thought the Ocean was too large to feel our impacts. Now, it may seem like our impacts are too large to solve. But we know this isn’t true.  

We have the technology, the knowledge, and the power to turn the tide and reverse our trajectory. 

We know this because we’re in many parts of the world, it’s already happening.  

Effectively managed Marine Protected Areas, Maximum Sustainable Yields (the maximum catch size that can be removed from a population to maintain a healthy and sustainable fish stock), and the rise in renewable energy technologies are all ways in which humanity has learned to collaborate more fairly with nature.  

Rainbow over a beach and the Ocean with the quote: We have the opportunity to leave our Ocean in a better state than we found it. Shared by Ocean Generation, leaders in environmental education.

Working with the Ocean rather against it can reap limitless benefits for both people and planet. If the Ocean thrives, so do we.

This knowledge is power.  
Power to be part of the solution, to consider the cost of inaction and unite to ensure our Ocean’s health is considered in all decisions – personal, business, and government policies.  

We have a unique opportunity to be the first generation to leave our precious Ocean in a better state than we found it.

COP28 Outcomes: The beginning of the end of fossil fuels

Young woman in a fashionable dress shirt floating in the Ocean. Her eyes are closed and she looks relaxed. Ocean Generation is sharing COP28 outcomes in this article with a focus on Ocean wins.

Everything you need to know about COP28 outcomes.

After a gruelling set of negotiations which dragged on well into the night, a new deal has finally been agreed at the UN climate summit COP28, in Dubai, UAE. 

COP28 outcomes: ‘Fossil fuels’ finally make the cut.

In the face of colossal opposition from the world’s oil producing countries, and despite the highest number of fossil fuel lobbyists at COP than ever before, a global consensus has been reached. The world has finally agreed to transition away from fossil fuels.  

For the first time ever, the elephant in the room has been addressed. ‘Fossil fuels’ have made it into the official outcome agreement at COP28.  

Environmentalists celebrate the results of COP28 because for the first time ever, 
‘fossil fuels’ have made it
into the official outcome 
agreement at COP28.  
Shared by Ocean Generation: Experts in Ocean health and Ocean conservation.

This is the biggest step forward for climate since the adoption of the Paris Agreement in 2015. And the COP28 agreement signals the beginning of the end of the fossil fuel era.   

The agreement follows the widespread fury sparked by an earlier draft, which was deemed a “death sentence” by representatives from Pacific Island nations. The new document calls on countries to “contribute to global efforts to transition away from fossil fuels in energy systems in a just, orderly and equitable manner.” 

The deal also calls for a tripling of global renewable energy capacity and doubling of energy efficiency by 2030. 

Ocean Generation questions if the COP28 outcomes go far enough to fighting the climate crisis. Alone, it won’t keep global temperature rise below 1.5˚C. But it may help the world to get closer to net zero by 2050.

Does the COP28 Agreement go far enough 

Despite the standing ovations as the new COP28 agreement was passed, many nations have criticised the final decision. And there are concerns that it hasn’t gone far enough.

With just six years left until 1.5 degrees becomes inevitable, it’s not the “phase-out” that we had all hoped for.  

Put simply, the language of the text was weaker than many countries wanted.  

There was no mention of coal or methane (the most potent greenhouse gas). A finance path to aid the transition for developing countries was also missing. There was also no request for developed countries to take the lead on the transition away from fossil fuels. This raised further criticisms over the fairness of the deal. 

A ‘litany of loopholes’ scattered within the text provides enough ambiguity for fossil fuel producers to continue ramping up production. Examples include ‘abatement’ (A.K.A CO2 removal); ‘transition fuels’ (A.K.A gas), and ‘fossil fuel subsidies’ to name a few.  

Loopholes in the COP28 agreement text provide ambiguity for fossil fuel producers to continue ramping up production. Shared by Ocean Generation: Experts in Ocean health and Ocean conservation.

This will have devastating consequences. Particularly, for the most vulnerable communities who are already bearing the brunt of the worsening impacts of climate change.  

Opposition to the new deal was voiced by a representative of Small Island Developing States (SIDS). The SIDS said: ‘You agreed the deal when we weren’t in the room’. This was meant literally (delegates from SIDS were still discussing their response to the text when it was agreed further down the hall). However, it also reflects that these nations feel overlooked, despite being the hardest hit by climate change.  

Does the COP28 Agreement go far enough 

The agreement alone will not be enough to keep global temperature rise below 1.5˚C. But it may help the world to get closer to net zero by 2050. That’s if individual countries put a rapid transition to green energy at the heart of their new NDCs. 

Here are some reactions from top climate scientists:

“At my lowest points as a climate scientist I did not think I would see a COP agreement that includes wording on the start of transitioning away from fossil fuels in my lifetime.”
– Prof Mary Gagen, Climate scientist, Swansea University  

“The agreement, though inadequate, is an essential and sustained baby step towards the goal of limiting human caused climate change.”
– Prof Richard Allan, Climate scientist, University of Reading

How does the Ocean fit into COP28 outcomes?

Multilateralism (alliance between countries to achieve a common goal) connects us all, and so does the Ocean.  

This was recognised during the Nature, Land Use and Ocean’s Day. Countries, non-state actors and other stakeholders came together in support of nature-based Ocean and climate action.

Here are our top three Ocean-wins from COP28: 

  1. The importance of maintaining the health of our Ocean is getting recognised.

    During the Nature, Land Use and Ocean’s Day, 18 countries pledged to implement Sustainable Ocean Plans. These plans are supported by the official launch of Ocean Breakthroughs.  

    These will provide a roadmap for change and aim to catalyse momentum across five key areas. Namely, marine conservation, shipping, aquatic food, coastal tourism, and marine renewables. These contributing countries represent 50% of the world’s coastlines and close to 50% of global Exclusive Economic Zones (EEZ’s). 

  2. There’s an increased appreciation that the Ocean can provide solutions for mitigation and adaptation.

    $186 million of new funding was pledged towards investment in nature-based solutions and Ocean-action. The Mangrove breakthrough was also formally endorsed by 21 countries. Its global goal is to protect 15 million hectares of mangroves

  3. And a growing acknowledgement of the need for synergy between climate and biodiversity targets.

    The joint statement on climate, nature and people was signed by 20 countries. It seeks to align action on climate change, biodiversity loss and sustainable development. It recognises that a healthy Ocean will provide benefits across all three avenues. 
Image of a woman and the Ocean. We cant solve the climate crisis without a healthy Ocean says David Eades, BBC Journalist and presenter. Shared by Ocean Generation: Experts in Ocean health and Ocean conservation.

What happens next?

For world leaders: While the COP28 decisions are not legally binding, Parties (countries) are obliged to act in accordance with the outcomes of this process. It’s time for world leaders to head home and begin delivering on the promises made. Individual countries are required to submit stronger action plans in their next round of Nationally Determined Contributions (NDCs) in 2025.  

For COP: Fossil fuels have officially entered the global conversation. The work now begins to tighten this language and ensure a fair, equitable and just transition at COP29 in Azerbaijan, and beyond. To ensure a liveable planet and a healthy Ocean, we need a full ‘phase-out’ of fossil fuels before it’s too late. 

For us: Together, we must ride this growing wave of hope and momentum, to continue advocating for stronger Ocean-action.
