What we do

Our ocean is at a tipping point. We're fighting to turn the tide on ocean pollution and restore the health of the seas.

    Tackle ocean pollution

    Every year, between 8 and 13 million tonnes of plastic enters our ocean. In fact, some areas of the ocean floor now have 1.9 million plastic pieces per square metre.

    If we don’t tackle pollution at source, these highly persistent chemicals and plastics will continue to increase in our ocean, causing untold damage. That's where we come in.

    Regenerate the ocean

    It's vital the ocean is as diverse as possible, and our restoration projects are working to do just that. From seagrass planting and oyster restoration to monitoring fish and working with coastal communities to protect species and habitats in their area, we’re working tirelessly to save the future of our ocean - halting biodiversity loss and ensuring nature can thrive again.

    Encourage proper marine management

    A third of our seas are called ‘protected’ – but they’re not; in practice, less than 1% of our seas are well-managed. We advocate, lobby and campaign to safeguard our seas – from calling for bans on destructive fishing practices to improving sustainability in aquaculture, we give the ocean a voice.

    Champion sustainable seafood

    Today, 90% of world fish stocks are fully or over-exploited from fishing. With added pressure from climate change and pollution, we’re moving into dangerous waters. Join us in making seafood more sustainable.

    Why we do it

    Our ocean covers over 70% of our planet. It provides more than half the oxygen we breathe and absorbs nearly a third of our carbon emissions.

    But today, it’s in crisis. From pollution to habitat destruction, the species that call the ocean home are being harmed. The ocean is losing its ability to help fight the climate crisis. We’re determined to change this. Together with communities, businesses and governments, we can make a difference
