Marine litter is more than an environmental problem, to be addressed by action plans and legislation. It is also a cultural problem, and must be addressed by efforts to change attitudes, behaviours, and management approaches.

We all have a role to play in this regard, by helping to build awareness of the damage done by litter to our seas and their wildlife, and to the people who use and depend on them
