Almost everywhere, climate change denial now looks as stupid and as unacceptable as Holocaust denial.

The corporations are powerful only because we have allowed them to be. In theory, it is we, not they, who mandate the state. But we have neglected our duty of citizenship, and they have taken advantage of our neglect to seize the reins of government.

The angry men know that this golden age (of fossil fuels) has gone; but they cannot find the words for the constraints they hate. Clutching their copies of Atlas Shrugged, they flail around, accusing those who would impede them of communism, fascism, religiosity, misanthropy, but knowing at heart that these restrictions are driven by something far more repulsive to the unrestrained man: the decencies we owe to other human beings.

We are often told we are materialistic. It seems to me, we are not materialistic enough. We have a disrespect for materials. We use it quickly and carelessly. If were genuinely materialistic people, we would understand where materials come from and where they go to. But, at the moment, the entire global economy seems to be built on the model of digging things up from one hole in the ground on one side of the earth, transporting them around the world, using them for a few days, and sticking them in a hole in the ground on the other side of the world.

Why is it so easy to save the banks - but so hard to save the biosphere?
