The occupation of America (and Columbus's arrival quite clearly was an occupation, no one can deny that) meant that the entire history of the Native Americans was rendered invisible. The land could only be occupied if it was first defined as empty. So it was defined as a wilderness, even though it had been used by native people for millennia.

It is only with local [agriculture] that we can manage the complexity and care that sustainability requires.

The problem of numbers can only be dealt with by recognizing that people have a fundamental right to economic security. If you provide them with economic and environmental security, the population will stabilize itself.

Diversity creates harmony, and harmony creates beauty, balance, bounty and peace in nature and society, in agriculture and culture, in science and in politics.

I didn't leave physics because of boredom. I left it because other issues compelled me in a bigger way. And I always say to myself, "When I'm 60, I'd like to go back to what I interrupted."

In England, the population explosion can be linked very clearly with the enclosure of the commons that uprooted the peasants from their land. In India, it was the same thing: the population increased at the end of the 18th century when the British took over and Indian lands were colonized. Instead of the land feeding Indian people it started to feed the British empire. So we had destitution. Destitute people who don't have their own land to feed themselves can only feed themselves by having larger numbers, therefore they multiply. It's the rational response of a dispossessed people.

It is often too late by the time the government reacts.
