Cowspiracy may be the most important film made to inspire saving the planet.

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.

If you can reach just 10 percent of the population, you can begin to reach a tipping point; that's where true social movements take place - it's a numbers game. And when you reach that number, the truth becomes obvious and empires of injustice crumble and fall.

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

What gives me hope is art - it's the most powerful weapons ever created. It's a weapon of mass construction.

To me, you’re either an activist or an inactivist.

Yes, we need to change, but simple changes can have profound impacts.
