We are in an environmental crisis which threatens the survival of this nation, and of the world as a suitable place of human habitation.

In general, any productive activity which introduces substances foreign to the natural environment runs a considerable risk of polluting it.

The environmental crisis arises from a fundamental fault: our systems of production - in industry, agriculture, energy and transportation - essential as they are, make people sick and die.

Perhaps the simplest example is a synthetic plastic, which unlike natural materials, is not degraded by biological decay. It therefore persists as rubbish or is burned-in both cases causing pollution. In the same way, a substance such as DDT or lead, which plays no role in the chemistry of life and interferes with the actions of substances that do, is bound to cause ecological damage if sufficiently concentrated.

No action is without its side effects.

In certain ways, I'm not very different than I was when I was a teenager.

The first law of ecology is that everything is related to everything else.---->I dont believe in environmentalism as the solution to anything. What I believe is that environmentalism illuminates the things that need to be done to solve all of the problems together.
