There are quick actions you can take online right now that will only take a few minutes.

Divers can also make a big difference by getting involved in underwater surveys with our Seasearch programme.

"I really believe the key thing that people should do is spend more time by, on or in the sea because that way they can begin to understand why it is so special and why marine conservation is so important. It makes the job of anyone involved that much easier because once someone has experienced how special our sea is, they will think twice about dropping litter on the beach or flushing plastic cotton buds down the loo."
