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.

If you inhale a millionth of a gram of plutonium, the surrounding cells receive a very, very high dose. Most die within that area, because it's an alpha emitter. The cells on the periphery remain viable. They mutate, and the regulatory genes are damaged. Years later, that person develops cancer. Now, that's true for radioactive iodine, that goes to the thyroid; cesium-137, that goes to the brain and muscles; strontium-90 goes to bone, causing bone cancer and leukemia.

The power of an aroused public is unbeatable.

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

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.

Terrorists do not actually need nuclear weapons. They have been conveniently supplied with 103 nuclear power plants scattered throughout the United States (438 of these deadly facilities exist throughout the world). A planned meltdown at one of these facilities would make the World Trade Center attacks seem like child's play. The massive concrete containers protecting the reactors are not strong enough to withstand the impact of a jumbo jet.

If the corporations have their way, the Earth will be killed, and that's in your lifetime. It's revolting to me that students are being trained to work in corporations. It's obscene to me that the corporations are running the world. We've got to get cross. Anger is an appropriate emotion.
