When politics is too slow, change has to come from culture.

I take no pleasure in the fact that the scientific predictions I’ve relayed to popular audiences turn out to be true.

If you look at the way all of the new reform movements dedicated to the public interest are living and thriving on the Internet, I do think there is still some considerable hope that the full participation of individuals in that conversation of democracy can once again restore the integrity of the way our democracy works.

A day will come when our children and grandchildren will look back and they'll ask one of two questions. Either they will ask: "what in God's name were they doing?" or they may look back and say: "how did they find the uncommon moral courage to rise above politics and redeem the promise of American democracy?"

We can believe in the future and work to achieve it and preserve it, or we can whirl blindly on, behaving as if one day there will be no children to inherit our legacy. The choice is ours; the earth is in balance.

Every nation has a moral obligation to safeguard the future.

In an economic recession, naturally, when you ask people to list their priorities, they're going to place a higher priority on the immediate economic situation.
