We are monumentally distracted by a pervasive technological culture that appears to have a life of its own, one that insists on our full attention, continually seducing us and pulling us away from the opportunity to experience directly the true meaning of our own lives.

All of us can make changes, but the changes that are most needed are not light bulbs and windows but laws and policies and treaties. So, yes, we are in a phase of this (climate protection) struggle where civic and political action is at the top of the list.

Some people accuse me of exaggeration, so let me be clear. Those people seek nothing less than the complete and utter destruction of the American way of life.

Global warming, along with the cutting and burning of forests and other critical habitats, is causing the loss of living species at a level comparable to the extinction event that wiped out the dinosaurs 65 million years ago. That event was believed to have been caused by a giant asteroid. This time it is not an asteroid colliding with the Earth and wreaking havoc: it is us.

Airplane travel is nature's way of making you look like your passport photo.

It's an important point, and every little bit helps not least because those who make those kinds of changes are more likely to make their voices heard as citizens. But the ultimate solutions are going to come through policies.

When our founders created America, it was in the age of the printing press, when individuals could freely join the conversation. And that robust, democratic dialogue more often than not lifted up the best available evidence and asserted what was more likely to be true than not.
