The world’s oceans are one of the primary reasons life on Earth exists at all. More than 50% of the oxygen we breathe doesn’t come from forests, but from phytoplankton drifting through our seas. At the same time, scientists estimate that the ocean absorbs roughly 25–30% of global CO₂ emissions, making it one of the planet’s most powerful climate buffers. And perhaps most striking of all, the ocean is home to nearly 80% of life on Earth. For humanity, it’s just as essential. Over 3 billion people rely on it for their daily livelihoods.
You’d think that with something this vital, we’d do everything in our power to protect it. Unfortunately, that’s not quite the case.
When it comes to environmental degradation, our oceans often bear the brunt. Plastic pollution remains one of the most visible threats, with an estimated 11 million metric tons entering the sea each year. And it’s not just bottles and bags, microplastics are now infiltrating marine ecosystems and, ultimately, our own food systems. In fact, it’s been suggested that the average person consumes the equivalent of a credit card’s worth of plastic annually. Not exactly appetizing.
Then there’s coral bleaching, driven by rising ocean temperatures. Coral reefs support around 25% of all marine species, meaning their decline has cascading effects across entire ecosystems. Add to that the pressures of industrial overfishing, habitat destruction, collapsing fish stocks, and bycatch that kills millions of non-target species like dolphins, sharks, and sea turtles, and the picture becomes even more urgent.
There’s no shortage of challenges facing our oceans, but this isn’t where we stay stuck. Instead, this week’s blog sets sail around the world, spotlighting the people, projects, and innovations redefining what ocean conservation can look like and proving that there’s still a course worth charting.
Scripps Institution of Oceanography (San Diego, U.S.A.)
In our quest to circumnavigate the globe by sea, we begin in San Diego, following the classic “westward route.” Just a few miles north, in the coastal enclave of La Jolla, sits the legendary Scripps Institution of Oceanography, part of UC San Diego and one of the oldest and most influential oceanographic institutions in the world.
For over a century, Scripps has been at the forefront of ocean science, producing groundbreaking research in areas like AI-driven ocean monitoring, the discovery of new marine species, and the long-term impacts of ocean acidification. Perhaps most famously, it is the birthplace of the Keeling Curve, the first clear, continuous evidence of rising atmospheric CO₂, forever changing how we understand climate change and the ocean’s role within it.
With its legacy of innovation and its continued influence on global ocean policy and research, Scripps is more than just a starting point on the map, it’s a fitting place to begin this journey into the future of ocean conservation.
Coral Gardeners (Moorea, French Polynesia)
Once we leave port in San Diego, the real journey begins: a Pacific crossing known among sailors as the “trade wind run.” It’s a long, uninterrupted stretch of blue water, roughly four to six weeks at sea, guided by steady winds and open horizon until land finally reappears in French Polynesia.
Our landfall brings us to Moorea, where Coral Gardeners was founded with a mission to restore the world’s reefs. Their approach is as hands-on as it is innovative: cultivating coral fragments in underwater nurseries and transplanting them onto degraded reefs to help rebuild entire ecosystems.
What sets Coral Gardeners apart isn’t just their evolving science, new techniques, technologies, and data-driven restoration, but their ability to turn conservation into a global movement. Through powerful storytelling and on-the-ground experiences, they’ve drawn in a wide audience, including advocates like Jason Momoa, Benedict Cumberbatch, and Shailene Woodley, who have all joined efforts in the water. It’s a reminder that saving coral reefs isn’t just a scientific pursuit. It’s a cultural one, too.
Pan-India Whale Shark Conservation Project (India)
From French Polynesia, we continue along the westward trade wind route, weaving through the islands of Southeast Asia and crossing the eastern Indian Ocean before making landfall in India.
Here, we encounter one of the most inspiring community-led conservation efforts in the region: the Pan-India Whale Shark Conservation Project, led by the Wildlife Trust of India. Whale sharks, the largest fish in the ocean, were once heavily hunted in Indian waters, primarily for their oil, which was used to waterproof boats. Today, that narrative has been dramatically rewritten.
The project takes a multifaceted approach, combining fisherman education and compensation programs with satellite tagging and research. By working directly with coastal communities, it has transformed former hunters into protectors. Through these community-led rescue efforts, more than 1,000 whale sharks have been saved, making it one of the most successful and compelling examples of grassroots marine conservation in the world.
Save Our Seas Foundation (Cape Town, South Africa)
After departing India, we continue across the expanse of the Indian Ocean, eventually tracing the coastline of Africa southward until we reach Cape Town.
Here, we find the Save Our Seas Foundation, one of the leading ocean-focused organizations based on the African continent. Their work is deeply rooted in marine conservation science, with a particular focus on sharks and rays, coral reef ecosystems, and the protection of critical marine habitats through protected areas.
Through a combination of research stations, global grant funding, and field expeditions across Africa and surrounding island nations, the foundation supports some of the most important marine science being conducted today. Alongside this, they invest heavily in education and outreach, bridging the gap between scientific discovery and public awareness, and helping shape a more informed and ocean-conscious future.
Parley (Brazil Chapter)
After a swift passage across the South Atlantic from Cape Town, we reach the coastline of Brazil, where one of the regional branches of Parley for the Oceans is actively working to combat marine plastic pollution.
Parley is one of the largest global NGOs tackling ocean plastics, with initiatives spanning coastlines around the world. In Brazil, their work focuses on large-scale beach and coastal cleanups, particularly at key interception points like rivers, mangroves, and remote marine environments where plastic accumulates before entering the open ocean.
But their impact goes far beyond cleanups. Parley’s model blends environmental action with cultural influence, collaborating with major brands to transform recovered plastic into recycled materials, while also investing in education programs across schools and coastal communities. Through partnerships with local NGOs, municipalities, and grassroots groups, they’re building a networked approach to ocean conservation that is as much about prevention and awareness as it is about removal.
Oceana (Copenhagen, Denmark)
From Brazil, we sail northeast with the South Atlantic trade winds, crossing from the tropical Atlantic into the North Atlantic. The journey carries us through increasingly busy shipping lanes, into the English Channel and onward to the North Sea, until we arrive in Copenhagen.
Here lies one of the key European hubs of Oceana, one of the largest organizations in the world dedicated exclusively to ocean conservation. While Oceana operates globally, its presence in Europe plays a critical role in shaping regional marine policy.
Their work is rooted in science-driven advocacy, conducting marine expeditions to gather the data needed to influence legislation and protect ocean ecosystems. From campaigning against overfishing and destructive fishing practices to safeguarding vital marine habitats, Oceana operates at the intersection of research and policy, turning data into tangible protections for the ocean.
It is here in Copenhagen that we bring our international voyage to a close, having explored just a small drop in the vast ocean of marine conservation efforts happening around the world. From cutting-edge research to community-led initiatives, from global awareness campaigns to policy-driven change, these organizations represent the many ways people are working to protect one of our planet’s most vital resources.
If anything, this journey is only a beginning. The ocean is expansive, complex, and still largely unexplored, not just in its ecosystems, but in the stories of those fighting to protect it. We hope this voyage sparks a deeper curiosity: to learn more, to look closer, and to recognize the collective effort unfolding across the globe to safeguard our oceans for generations to come.
