What we do

The Marine Conservation Society is the UK’s leading charity for the protection of our seas, shores and wildlife. For over thirty years MCS has been the voice for the sea for all the fascinating creatures that live beneath the waves, for our breath-taking coastal environment, for all those who make a sustainable living from the sea and for everyone who simply enjoys visiting the beach and our glorious coastline.

Clean seas

Let’s work together to turn the tide on pollution and rubbish in our seas
and on our beaches.

Help protect marine wildlife

We need to secure £50,000 for the next two years to make the case for new Marine Protected Areas and survey existing sites to prove just how effective they are. Your support is vital in helping us make this happen.
