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 whole world is being 'deculturalized' into a uniform 'Coca-Cola society,' wanting and needing an American way of life.

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