Wheel of Fortune host Pat Sajak recently outed himself as a climate change denier . Fair enough. Everyone's entitled to their opinion, even if it makes them look ignorant. That aside, what frustrates me most about the situation isn't that people are rejecting science in favor of their own, rather poor common sense. No, that's bad enough. What really saddens me is how badly we, as human beings, seem to plan for the future. Our very survival depends -- first and foremost -- on a viable planet for us to sustain a continuation of the species. Even if you want to contend that humanity isn't the primary cause of global warming, then at the very least you have to admit that we shouldn't help it along. After all, a person diagnosed with lung cancer is doing his or herself no favors by taking-up smoking, right?
