The Sky is falling!!!!!
Most of the positive posts here have generally said we should take action to avoid a cateclysmic change in the future. Zero control! We have no defense at all against a global cateclysmic event except to vacate said premises, and we are not even close to ready to do that.
Fund NASA! Fund NASA!
Almost everyone has shaded their comments with a hint that human action is not natural; e.g., human intervention. Whatever humans do on this planet or elsewhere in the universe is entirely natural to the environment. We are not aliens in this universe. If we erode the planet or use up its energy resources that depletion is a natural depletion caused by natural organizisms on and of the planet. It's sort of analygous to the depletion of a radioactive isotope.
Now, that being said and the guilt from intelligent self-awareness being assuaged, let's clean this mess up!
