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

Nothing ever dies, nothing ever goes away.

The modern technologist is less 'sorcerer' and more 'sorcerer's apprentice'.

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.

Because the global ecosystem is a connected whole, in which nothing can be gained or lost and which is not subject to over-all improvement, anything extracted from it by human effort must be replaced. Payment of this price cannot be avoided; it can only be delayed. The present environmental crisis is a warning that we have delayed nearly too long.

The age of innocent faith in science and technology may be over.

What is needed now is a transformation of the major systems of production more profound than even the sweeping post-World War II changes in production technology.
