Our planet is currently undergoing a mass extinction of species called the Anthropocene - the Age of Man.

A vegetarian driving a Hummer emits less carbon than a meat eater on a bicycle.

I want to do the most subversive thing I couldn't do as a child: I want to take back the planet's future.

I lived through the Cold War as a child, and we always thought a nuclear bomb could end life everywhere at any time. On one hand, it created an atmosphere where you lived for the moment - because it could end at any second - but on the other, it warped a generation into thinking t there was no reasonable expectation of building a future that could be vaporized at any moment by a few morons.

Change doesn't need to be overwhelming; it is not impossible.
