Answer 2

Most pollutants are eaten by something or simply decompose.  For example, petroleum is eaten by bacteria as well as chemically oxidizing.

Answer 3

There is the water cycle. It takes the water out of the oceans by evaporation so it is distilled water in the rain.

Answer 4

Everything in nature has it's place.  What's waste to you and me is dinner for the next guy down the line.  It took billions of years of evolution to get it right.

The trouble is we are producing thousands of new synthetic chemicals every year that have no place in the natural environment, cannot be metabolized, cannot be decomposed.

Oysters are natures filters.
