The very energy sources that have gotten us to where we are now are also, if we continue doing what we're doing, a shortcut to the end of all that we hold near and dear.

Our insatiable appetite for fossil fuels and the corporate mandate to maximize shareholder value encourages drilling without taking into account the costs to the ocean, even without major spills.

We've got to somehow stabilize our connection to nature so that in 50 years from now, 500 years, 5,000 years from now there will still be a wild system and respect for what it takes to sustain us.

If I seem like a radical it's because I have seen things that others have not.

There is not a well-funded campaign among scientists to say, "Look, here's the evidence. You can read it yourself. Here are the facts. We're not making this up."

It's an appreciation for life generally, every bit of life, the smallest creature that lives in the intestines of termites that make termite life possible - to the leaves that turn out oxygen and grab carbon dioxide and with water make simple sugars that feed much of the world. I mean, these are everyday miracles.

I have lots of heroes: anyone and everyone who does whatever they can to leave the natural world better than they found it.
