Now is not the time to repudiate environmental balance, but rather it is the time for all of us to work together - politician, advocate, rancher, scientist, and citizen. Only by doing this will the United States move forward and be a leader in environmental issues and ensure sustainability to our delicate ecosystem.

I did not, like my children and people today, grow up with television as part of my life.

I love making films more than anything, but it's tough.

I guess the optimistic thing is that those people in Congress who are climate deniers, I think their time has run out.

San Franciscans are very proud of their city, and they should be. It’s the most beautiful place in the world.

I've been very fortunate in that I've had wonderful relationships with people I've worked with.

The meter is ticking [particularly in the face of climate change], so you've got to get to as much as you can as fast as you can. I grew up with 'This Land Is Our Land,' and public land doesn't belong to that administration or this one. We want our kids to grow up with real natural places, not just photos of them.
