Disgustingly rational, as usual, Tom.
I believe we humans do have an effect on the environment. The question is my mind is, what, and how serious, is the result of that effect.
Regardless, I am in favor of reducing our dependence on fossil fuels if for no other reason than we don't have a native supply sufficient for our needs and must rely on the resources of others, some of whom would prefer we would just disappear in a puff of smoke and are likely supporting efforts to achieve that very end.
I long for the day (and, regrettably will never see it in my lifetime) when we say "thanks, but no thanks. You can drink your oil for all we care." If reducing our dependence on others has a salubrious effect on the environment, so much the better.
