I love this planet I want to see the environment preserved and I want to see the human race preserved. And I'd like to see everybody living decently in a more equitable, kind-hearted, thoughtful, generous world.

We'll be eight degrees hotter in ten -- not ten, but thirty or forty years, and basically none of the crops will grow. Most of the people will have died and the rest of us will be cannibals.

A total population of 250-300 million people, a 95% decline from present levels, would be ideal.

The sad thing about destroying the environment is that we're going to take the rest of life with us. The bluebirds will be gone, and the elephants will be gone, and the tigers will be gone, and the pandas will be gone.

Hell, we spent $200 Billion to get a scared guy who needed a shave out of a fox-hole! And he may even die of prostate cancer before we even get a chance to try him, dammit!

I don't measure success in numbers, but I consider my contributions of more than $1.3 billion to various causes over the years to be one of my proudest accomplishments and the best investment I've ever made. Those dollars have improved lives, saved species, fought disease, educated children, inspired change, challenged ideas and opened minds; at the time of my death, virtually all of my wealth will have gone to charity.

Every few seconds it changes - up an eighth, down an eighth - it's like playing a slot machine. I lose $20 million, I gain $20 million.
