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.

Delhi is locked in a complete choking smog at the moment - they've had to close schools in one of the world's biggest cities. They have their own reasons for needing to get off fossil fuels fast.

A voluntary simplification of life-styles is not beyond our abilities, but it is probably outside our desires.

We have built a greenhouse, a human greenhouse, where once there bloomed a sweet and wild garden.

I don't know how to make people who absolutely have to be obsessed with paying a week's energy bills... obsessed with climate change... It's very hard.

We had other currencies that we could find work in - the currencies of movements: passion, spirit, creativity.
