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.

as a physician I examine the dying planet as I do a dying patient. The earth has a natural system of interacting homeostatic mechanisms similar to the human body's. If one system is diseased, like the ozone layer, then other systems develop abnormalities in function - the crops will die, the plankton will be damaged, and the eyes of all creatures on the planet will become diseased and vision impaired.

Patriotism is nationalism, and always leads to war.

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.
