We're the Marine Conservation Society, the leading environmental ocean charity. We're working towards a cleaner, better protected, healthier ocean. Will you join us?
Source to Sea Litter Survey
No matter where you live across the UK, you can help keep our seas clean. Most of the litter that ends up on our beaches or in the sea starts its journey in villages, towns and cities miles from the coast.
World Ocean Week
We've got a week-long celebration planned to honour World Ocean Day. Get involved in clean-ups, creative campaigns and community events, all leading up to the UK’s game-changing Deposit Return Schemes in 2027.
Clean Water Now
Along with 40 other organisations, we're demanding Clean Water Now from the UK Government, to achieve our goal of sewage-free seas.
How you can save the ocean
Whether you live inland or by the coast, there are lots of ways you can become a champion for our seas.
