"The most important thing for our species is, before it speaks, to listen to its environment. That has a higher priority in any species' survival. We need to be listening to our environment - in other words, restoring the quiet - not just to our natural areas, but also to towns like Portland, Maine."

There are two ways you can receive energy from your environment: One is molecules bumping against you. That's the air. The other is radiative energy. That's what you're feeling from the sun. When they say "Get out of the sun, out of the heat," the air is the same temperature; it's just you're exposed to sunlight.
