Water never goes away, it simply relocates or changes form. Air moves around all day long. Trees grow and are harvested. All of these commodities present different problems, but oil and land are not replaceable. As a biologist with a minor in conservation, I feel very protective of land and consider those who permanently damage it for no reason are criminals. Same for wasting oil. Saddam should swing at daybreak just for setting 1500 oil wells on fire, separate from his other atrocities.
