I saw a show not long ago that was documenting the wild life out in the Pacific Ocean islands and the amount of trash that has washed up on the shores of these islands, some only inhabited by animals, was astonishing to say the least. On some of the beaches you couldn't even see the sand. Countries dump so much trash in the ocean and the problem is that plastic not only floats, but it doesn't break down. The tides carry all the plastic for 100s and 1000s of miles and it ends up on these beaches. It was really sad.
