My goal is to make the biggest difference possible in the world. I have only so many resources and so much time.

My goal was to leverage the power of movies and the reach they have and include important messages. Of course, they still have to be entertaining so that people will watch them, but I wanted to make sure there was a message, a takeaway.

My goal was to be at the point - no older than 40 - where I would have enough resources to make a difference in the lives of disadvantaged people.

I backpacked around the world and went to places like Mexico City and Pakistan, where I'm like, 'Oh. Things aren't quite as good.'

For millions of Americans, climate change is no longer just a chart or a graph. It's the smoke on our tongues from massive wildfires. It's the floodwater invading our homes and record-breaking hurricanes and heat waves.

I don't really give into all that philosophical talks that 'money is not everything.'

I'm not an extreme tree-hugger. I do believe trees grow and are a useful agricultural product that can be harvested without damaging the ecology and wildlife.

We're running the most dangerous experiment in history right now, which is to see how much carbon dioxide the atmosphere... can handle before there is an environmental catastrophe.
