To me the analogy [to climate change] is... doctors worry a lot about cholesterol. And if you go to the doctor, and the doctor says "oh, your life would be happier if you ate a different diet and exercised" people pay no attention.

We are altering the most basic forces of the planet's surface - the content of the sunlight, the temperature and aridity - and that brings out the most powerful questions about who is in charge. If you wanted to give a name to this theological problem, I think you could say that we are engaged in decreation.

If we continue to think of ourselves mostly as consumers, it's going to be very hard to bring our environmental troubles under control. But it's also going to be very hard to live the rounded and joyful lives that could be ours. This is a subversive volume in all the best ways!

If it's wrong to wreck the planet, it's wrong to profit from the wreckage.

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.

Colonialism of one kind or another, imperialism of one kind or another, and slavery, and on and on and on.

Climate change is the single biggest thing that humans have ever done on this planet. The one thing that needs to be bigger is our movement to stop it.
