My three main goals would be to reduce human population to about 100 million worldwide, destroy the industrial infrastructure and see wilderness, with it's full complement of species, returning throughout the world.

An Ice Age is coming and I welcome it as much-needed changing. I see no solution to our ruination of earth except for a drastic reduction of the human population.

The optimum human population of earth is zero.

We must make this an insecure and inhospitable place for capitalists and their projects. We must reclaim the roads and plowed land, halt dam constructions, tear down existing dams, free shackled rivers and return to wilderness millions of acres of previously settled land.

Humanity is the cancer of nature.

I founded Friends of the Earth to make the Sierra Club look reasonable. Then I founded the Earth Island Institute to make Friends of the Earth seem reasonable.

Capitalism is a cancer in the biosphere.
