By using innovative solutions to safeguard ocean biodiversity, we've collectively given space for rewilding to take place. We’re working with local communities to protect the seabed. In the south of England, our project has driven a 212% increase in seagrass cover following the installation of protective measures, benefitting wildlife, people, and planet.

We’re reintroducing native oysters to Scottish seas. Oysters play a vital role in supporting ocean recovery, forming reefs which provide habitat for marine life, and filtering up to 200 litres of water per day. With an 85% global decline in oyster numbers, we’re working to reverse this trend through pioneering projects.

Reducing ocean sewage
With sewage-free seas we can turn the tide on poor water quality and achieve ocean recovery. We’ve taken the UK Government to the High Court to ensure our seas are properly protected from sewage pollution, safeguarding vital habitats and species. We work to ensure clean seas for wildlife, people, and planet.
