When we design our national R&D programs, we ought to ensure a place for the small, the new, and the cutting-edge.

Healing is a moral thing to do.

President Bush's proposal to focus our resources on sending humans to Mars is intriguing, but it is not the most compelling reason that Americans ought to focus our interest on the Red Planet.

What is a fish without a river? What is a bird without a tree to nest in? What is an Endangered Species Act without any enforcement mechanism to ensure their habitat is protected? It is nothing.

We could never light another match, and if China continues to build one coal-fired power plant a week, we are doomed. China is going to have to have new technologies made available to it to stop this. They're not going to live in poverty.

I would like to see whoever is our next president dedicate a significant part of their inaugural address to this challenge. We have to ignite the nation's energies and passions on this to make this happen. I think we do need the same kind of inspiration we had from Kennedy in his inaugural address in 1961.

We [USA and China] have a common responsibility with different numerical targets, and that's the situation ultimately we are going to have with China. We emit six times more per person than they do. It's hard to tell them to cut theirs in half right now until we start moving. Being the ostrich with your head in the sand and tail feathers in the air like some would have us to do while China continues to pollute is simply not an option.
