The planet's oceans are rapidly becoming the world's trash dump. Every mile of ocean now contains an average of 74,000 pieces of plastic. A "plastic soup” of waste, killing hundreds of thousands of animals every year and as chemicals trickle slowly up the food chain. In California, conservationists are seeing increasing numbers of whales and dolphins die agonizing deaths. Their intestines blocked with plastics and other trash.
Plastic floats. The World’s biggest plastic dumps are at sea. Millions of tons enter the ocean every year, pouring out from rivers and shores, ships and platforms. The world’s scientists have studied the phenomenon with alarming results.
