The world hasn't ended, but the world as we know it has-even if we don't quite know it yet.

We also have to engage - and I think this is important - in national politics because there is no way to address questions of this scale in the short time that we have to address them without engaging in real political change.

I think I have felt most profoundly that in our disruption of the most basic physical processes of creation, we are engaged not only in the act of suicidal self-destructiveness, but also in an act of thorough-going blasphemy.

We'll never get there if we let the climate crisis bloom unchecked, so for the moment the key is to organize, organize, organize!

If we were built, what were we built for? ... Why do we have this amazing collection of sinews, senses, and sensibilities? Were we really designed in order to recline on the couch, extending our wrists perpendicular to the floor so we can flick through the television's offerings? Were we really designed in order to shop some more so the economy can grow some more? Or were we designed to experience the great epiphanies that come from contact with each other and with the natural world?

I'm guessing the most efficient way would be to transfer an awful lot of technology, but also direct aid to deal with climate emergencies already underway. Hillary [Clinton] has already said $100 billion a year would be appropriate.

Probably nothing that we have ever managed to do quite equals the basic undermining of the physical stability of the planet on which most of the world's poor people depend.
