Compost also reduces water pollution. Organic wastes, such as grass clippings and leaves, contribute to non-point source pollution (that's pollution that enters the waters in diffuse sources, such as runoff from streets). When yard waste decomposes in the water excess nutrients are released and oxygen is depleted. . . making a horrible environment for aquatic life.

One of the important things to remember about home composting is that you want to make the critters that do the all work happy. Summer can dry up a compost pile, so it is important to make sure there is moisture in your pile (as wet as a wrung-out sponge).
