When we walk along the coast we often focus on what we are pleased to see - the wind-blown patterns in the sand, the crystal clear waves crashing on the rocks and the tide rushing up the beach. We see the plovers, gulls, kingfishers and other birds and it pleases us.
But then we become conscious of less attractive features - the plastic debris, bottles, containers, fragments of nets and worse ... the flotsam and jetsam of careless, thoughtless individuals. The sort of people who led Jacques Yves Cousteau to describe the sea as the universal sewer.
The place where so much of our waste ends up ... when will it stop?
