Immigration is one of the leading contributors to population growth.

I reject the idea that humans are superior to other life forms. . . Man is just an ape with an overly developed sense of superiority.

All consumption should be local. No food products need to be transported over hundreds of miles to market. All commercial fishing should be abolished. If local communities need to fish the fish should be caught individually by hand. We need to stop flying, stop driving cars, and jetting around on marine recreational vehicles.

We're just a conceited, naked ape. But in our minds we're some sort of "divine legend," and we see ourselves as some sort of god. That we can walk around the earth deciding who will live and who will die and what will be destroyed and what will be saved. But the fact is we're just a bunch of primates out of control.

We need to radically and intelligently reduce human populations to fewer than one billion. We need to eliminate nationalism and tribalism and become Earthlings. And as Earthlings, we need to recognize that all the other species that live on this planet are also fellow citizens and also Earthlings. This is a planet of incredible diversity of life-forms; it is not a planet of one species as many of us believe.

I can assure you no whales are going to be killed today.

We are killing our host the planet Earth.... I was once severely criticized for describing human beings as being the 'AIDS of the Earth.' I make no apologies for that statement.... We need to radically and intelligently reduce human populations to fewer than one billion.
