There's even garbage in the deepest reaches of the world?s oceans.
Japanese scientists recently discovered a plastic bag near the bottom of the Mariana Trench.
They cataloged 3,425 cans, bits of plastic and stray fishing gear, mostly in the Pacific Ocean.
Much waste in floating trash fields is too small to be seen, but is still doing widespread damage to sea life.
