People power and science. The perfect partnership

“Over the last two decades I’ve watched with horror as the future of our ocean has become more and more uncertain. That’s not to say it’s not recoverable it absolutely is. But only if we can work with people just like you – who care as passionately about our seas as our team of scientists and experts do.”

Dr Peter Richardson, Head of Ocean Recovery, Marine Conservation Society

For nearly 40 years we’ve championed our seas

  • We’ve seen a 55% drop in plastic bags on UK beaches since the 5p charge (which we campaigned for) was introduced in 2011.
  • UK Marine Conservation Zones were designated using our divers’ habitat and species reports
  • Evidence from our beach litter surveys helped bring in the bans on plastic cotton bud sticks, stirrers and straws
