All things considered, the internet seems fairly environmentally benign to me. The last stats I saw showed you could do 1,000 Google searches for the gas it took to drive six-tenths of a mile. But the internet can't substitute for real connection and community.

I've spent my life living in rural America, some of it in blue state Vermont, some of it in red state upstate New York. They're quite alike in many ways. And quite wonderful. It's important that even in an urbanized and suburbanized country, we continue to take rural America seriously. And the thing that makes Vermont in particular so special, and I hope this book captures some of it, is the basic underlying civility of its political life. That's rooted in the town meeting. Each of the towns in Vermont governs itself.

Especially in recent years, the more and more we understand what we are doing, the more we have the science to tell us what we're doing, the fact that we continue to do it without taking steps to address it strikes me as, among many other things, irreverent in an extreme.

A spiritual voice is urgently needed to underline the fact that global warming is already causing human anguish and mortality in our nation and abroad, and much more will occur in the future without rapid action.

In the States, the movement's actually gotten much much much stronger. There really was no climate movement so to speak before that - I think because everybody assumed that reasonable heads would prevail and do the right thing - and why would you need to have a huge movement in order to cause our leaders to deal with the most serious problem that they face. In a rational world you wouldn't. They would deal with it.

It's our own throat that we are cutting in the end along with everyone else's. We need to be exercising precisely the kind of leadership that might allow us to nudge China and India, say, onto different energy trajectories, in order to improve our own chances of surviving this century.

In fact, corporations are the infants of our society - they know very little except how to grow (though they're very good at that), and they howl when you set limits. Socializing them is the work of politics. It's about time we took it up again.
