We'll never get there if we let the climate crisis bloom unchecked, so for the moment the key is to organize, organize, organize!

The seasons don't matter to most of us anymore except as spectacles. In my county and in many places around this part of the nation, the fair that once marked the harvest now takes place in late August, while tourist dollars are still in heavy circulation. Why celebrate the harvest when you harvest every week with a shopping cart?

Between [Speaker of the House] Paul Ryan, [Senate Majority Leader] Mitch McConnell, and Donald Trump's team, I don't see a lot of openings for making real progress.

To me the analogy [to climate change] is... doctors worry a lot about cholesterol. And if you go to the doctor, and the doctor says "oh, your life would be happier if you ate a different diet and exercised" people pay no attention.

After a lifetime of nature shows and magazine photos, we arrive at the woods conditioned to expect splendor - surprised when the parking lot does not contain a snarl of animals attractively mating and killing each other.

My goal was to have as many of the primary sources as I could made available for people to look at and understand. Climate change is probably the most important thing that's ever happened, and yet people's understanding of it and its history remains a little fuzzy.

The end of nature sours all my material pleasures. The prospect of living in a genetically engineered world sickens me. And yet it is toward such a world that our belief in endless material advancement hurries us. As long as that desire drives us, here is no way to set limits.
