The tragedy is that there is so much more incentive - money - to destroy the ecology than there is to preserve it.

I have actually led more expeditions to Antarctica than Scott, Amundsen, and Shackleton put together.

People are beginning to realize that we need to live in accordance with the law of ecology, the law of finite resources, and if we don't, we're going to go extinct.

I don't see the point in making a distinction between natives having more of a right to kill whales than nonnative people.

I used to swim with these beavers in a beaver pond when I was 10. I went back when I was 11 and found there were no more beavers. I found that trappers had taken them all, so I became quite angry, and that winter I began to walk the trap lines and free animals from the traps and destroy the traps.

I take a biocentric point of view. I look at things from the point of view of the Earth and the laws of ecology. As opposed to the anthropocentric point of view, where everything revolves around humanity.
