There are "eco-nuts" in this world. In my mind they chase small problems, while larger grave problems are ignored. Most have their hearts in the right place, but even though managing a sustainable society should be a necessary policy, which our leaders rarely if ever mention, cost benefit analysis needs to be applied to all of our environmental problem.
By far and away the most dangerous pollution produced by humans are radioactive isotopes. There have been dozens of above ground atomic bomb tests and power plants accidents which have dispersed radioactive isotopes over every square inch of the planet. Some nuclear power plants, like Fukushima, are actively poisoning the Pacific Ocean and this is not an isolated event. There are about 222 radioactive isotopes that mankind is aware of and has produced as a result of developing nuclear power and nuclear weapons. These isotopes cause cancer, birth defects ad raise infant mortality. Human civilization is about 15,000 years old. Containing these poisons are a ridiculously difficult management problem because their half lives are so long. Here are just three examples:
iodine-129: 15,700,000 years, this stuff destroys your thyroid and kills babies.
uranium-235: 704,000,000 years, deadly
plutonium-239: 24,110,000 years deadly
Polonium-210: 138 days, this is the stuff that poisoned Mr. Litvinenko, who died a horrible death.
By in large NONE of these pollution problems are being handled in a manner consistent with public safety. If you are downwind you are at great risk and your government will deny any culpability. But, its worse than that, we are all exposed to these pollutants all the time because they were never managed properly.
Oil pollution, by comparison, has a full life of about 100 years, an ugly, but manageable problem (depending on its concentration).
Competition between the USA and Russia has placed untold risks to life on earth. Yet, this problem has never been addressed in an intelligent manner. Instead our Government has consistently covered up and denied the risks. If your Iraqi baby is born without any hands is the USA liable?
