Environmental issues are far more complex than any brief overview can present.
We can begin, however, by recognizing that the Green Movement is not a fad. Environment has grown in importance as a contemporary business issue and will continue growing for a long time. Jacquelyn Ottman, in her book Green Marketing, states that used motor oil is the largest single source of pollution in our nation's waterways. The authors of this website state that only 14 percent is re-cycled and the rest, 9.5 million gallons, is dumped, either into sewers, on the ground or into the trash. Extrapolate this out and you are looking at some awesomely large numbers nationally.
