We'd like to get the fossil fuel industry on the back foot for a while, having to deal with us.

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.

The technology we need most badly is the technology of community, the knowledge about how to cooperate to get things done.

Very few people on earth ever get to say: 'I am doing, right now, the most important thing I could possibly be doing.' If you'll join this fight that's what you'll get to say
