All major changes are like death. You can't see to the other side until you are there.

Face the facts, all these environmental organizations are thirty, forty, fifty years old. They have big buildings, big obligations, big staffs.

...scientific power is like inherited wealth: attained without discipline. You read what others have done, and you take the next step.

That hope is science.
