The abundance that is offered to us by leaving behind the fossil fuel paradigm is very promising for the world and the people of the world. We will have cleaner air, water, and food; we will have more resources to share with our people. There will be more economic freedom because people will be able to harvest their own energy.

I am grateful to the fossil fuel industry for bringing us the concentrated carbon that took us through the Industrial Revolution and through the technological revolution and brought us to the gateway of the renewable energy revolution, or what I call the sunlight revolution. But that is where we must part ways. It's the natural order.

I didn't like the distance between my family and myself that I was experiencing from having to work all the time.

I didn't really have any interest in producing anything.

Ask people who are close to the natural world: farmers, people who work the land or in some way use the land for their livelihoods. They will tell you what they are seeing isn't so good. They will tell you the changes they have seen in the past twenty years are remarkable in one way or another and unlike anything they had seen before that.

Graduates, I'm asking each of you, at some point, to act up, be misbehaved. Buck the system. Fight for what you believe in. This is the time to do it. You're the ones to do it. Your world, is like no other generation, you actually get to create the world that you can imagine.

My kids get very upset with me when I leave to do film work, but they have a lot of patience with me when I leave to do environmental work.
