“Continual miniaturisation allows resources to be conserved, efficiency to be increased, pollution to be reduced, and the remarkable flexibilities of the quantum world to be tapped.”

1970s
Context: Pollution is nothing but resources we're not harvesting. We allow them to disperse because we've been ignorant of their value. But if we got onto a planning planning basis, the government could trap pollutants in the stacks and spillages and get back more money than this would cost out of the stockpiled chemistries they'd be collecting.
Margaret Mead gets cross with me when I talk like this because she says people are doing some very important things because they're worried and excited and I'm going to make them relax and stop doing those things. But we're dealing with something much bigger than we're accustomed to understanding, we're on a very large course indeed. You speak of racism, for example, and I tell you that there's no such thing as race. The point is that racism is the product of tribalism and ignorance and both are falling victim to communications and world-around literacy.

Context: Acknowledging the physical realities of our planet does not mean a dismal future of endless sacrifice. In fact, acknowledging these realities is the first step in dealing with them. We can meet the resource problems of the world — water, food, minerals, farmlands, forests, overpopulation, pollution — if we tackle them with courage and foresight.
