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 first law of ecology is that everything is related to everything else.

Nothing ever dies, nothing ever goes away.

Seen that way, the wholesale transformation of production technologies that is mandated by pollution prevention creates a new surge of economic development.

Technologists practice faith too; 'Faith that problems have solutions before having the knowledge to solve them.'

My entry into the environmental arena was through the issue that so dramatically - and destructively - demonstrates the link between science and social action: nuclear weapons.

The AEC scientists were so narrowly focused on arming the United States for nuclear war that they failed to perceive facts - even widely known ones - that were outside their limited field of vision.
