I think the environmental movement is the biggest people's movement in the world. Unfortunately, our governments and corporations haven't responded accordingly to protect our planet's natural resources.

I urge individuals around the world to stand up, and ask local leaders, if they haven't already, to pledge to purchase cleaner cars, build green facilities, and buy green power like wind or solar energy. Our actions may determine if we become a casualty in the war for a habitable planet for generations to come.

I don't think my parents would be shocked about anything I did, because they're so laid-back.

Like everything, personal relationships and all that stuff is sort of put on ice while you go off to your location for five or six months. So, do I feel more settled in my life and in my work? Absolutely, yeah.

If you can do what you do best and be happy, you're further along in life than most people.

Now is the time to divest and invest to let our world leaders know that we, as individuals and institutions, are taking action to address climate change, and we expect them to do their part this December in Paris at the U.N. climate talks.

If we do not act together, we will surely perish.
