No anti-slavery crusader aimed for a partial solution or settled on a regimen of interim targets. The fight to end slavery was a fight to end 100 percent of slavery for all time. In just that way, we can't settle for partial measures if we are going to win the war for our world. We need to fight for 100 percent sustainability, now.

The vision of the ideal life that we've been taught in the West, which is gaining ever more purchase in China and India and elsewhere, feeds the system we need to undo. Go to school in order to get a degree in order to get a job in order to earn money so you can try to buy happiness because your life sucks, then retire and die: this is not meaningful living.

What you buy doesn't make you cool, it makes you the opposite. Stop buying stuff just to have more stuff. Most of us have enough of everything already. Let's care for what we've got, instead, and dispose of our disposable society.

There is simply no issue more important. Conservation is the preservation of human life on earth, and that, above all else, is worth fighting for.

The Earth should not be a worse place after my life than it was when I was born here.
