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.
