Once we open the door to the plutonium economy, we expose ourselves to absolutely terrible, horrifying risks from these people.

There are many different kinds of radioactive waste and each has its own half-life so, just to be on the safe side and to simplify matters, I base my calculations on the worst one and that's plutonium.

The Sierra Club is a very good and a very powerful force for conservation and, as a matter of fact, has grown faster since I left than it was growing while I was there! It must be doing something right.

Yet another proposal would have us rocket the waste into the sun, but, as you're probably aware, about one in ten of our space shots doesn't quite make it out of the earth's gravitational field.

When people say, 'You're not being realistic,' they're just trying to tag some thoughts that they can't otherwise handle.

It is absolutely imperative that we protect, preserve and pass on this genetic heritage for man and every other living thing in as good a condition as we received it.

You don't have a conservation policy unless you have a population policy.
