It is clear to me that unless we connect directly with the earth, we will not have the faintest clue why we should save it.

On one hand, I'm an optimistic pessimist. On the other, I'm a pessimistic optimist. But while there's life, there's still hope, and I wouldn't be doing what I'm doing if I didn't think there was still hope.

We are the curators of life on earth. We hold it in the palm of our hand.

The massive quantities of radiation that would be released in a war fought with nuclear weapons might, over time, cause such great changes in the human gene pool that following generations might not be recognizable as human beings.

The U.S. population, a mere four or five percent of the world total, creates half the world's toxic waste.

Every time you turn on an electric light, you are making another brainless baby.

Nuclear industry proponents often assert that low doses of radiation (eg below 100mSV) produce no ill effects and are therefore safe. But , as the US National Academy of Sciences BEIR VII report has concluded, no dose of radiation is safe, however small, including background radiation; exposure is cumulative and adds to an individual's risk of developing cancer.
