I'm gonna throw in my 2 cents worth.....
First of all I believe we should take care of the planet. However, I am not a "tree hugging liberal" who believes we should only eat roots, wear leaves and drive hybrids. Nor do I believe that if someone doesn't do those things they are "killing the planet" and should be chastised, criticized and treated like a leper.
The fundamental problem with this debate is that the people in the "global warming/cooling/climate change" camp (I do find it odd that the name for this "crisis" changes more often than Al Gore changes his socks) some how feel it is necessary to constantly berate those of us who question the "science". I have never been a sheep who just blindly follows what I am "told" by the "experts". I like to actually read and figure things out for myself. If I chose to do my own research and base my opinions on my findings that doesn't make me "anti" anything - except maybe status quo.
And, just because some guy with more money than me says I should recycle and not burn fossil fuels (all the while he is doing just what he said I shouldn't) doesn't mean I'm just gonna say "yes sir" and fall in line. It makes me question all these "famous" environmentalists who don't seem to practice what they preach. Hypocrisy ALWAYS makes me question motives.
Do I think the climate is changing - yes like it has for millions of years before us. After all we did have an ice age, the dinosaurs did go extinct. However, I don't recall any paleontologist discovering a Hummer next to the Tyrannosaurus Rex bones.
When we try to "fix" things more often than not we screw them up worse. Look at the mess the National Parks keeps creating in YellowStone when they try to "fix" the animal population problem. There never would have been a population problem if we hadn't tried to "fix" the predator problem.
Fire ants in the south "problem" brought on by people trying to "fix" a different insect invasion problem, which was brought on when people imported non-native species to control an beetle "problem".
The point here is that we more often than not make more of a mess than the mess we were trying to "fix" in the first place.
Lastly, I believe that there will never be a complete agreement on this topic. It's like peace in the middle east, religion, abortion and a hundred other topics that are "controversial". Further, I think it is completely counter productive to call names, insinuate people are uneducated and/or that they don't care, or to throw out any other insult to people's intelligence, back ground, political affiliation whether blatantly or otherwise, just because they do not agree with your point of view.
Just because I don't agree with your world view doesn't mean I don't know what I'm talking about. It doesn't mean my values, opinions, ideas are not valid. We, as a whole tend to get so "dug in" in our opinions that we immediately discount someone else's view if they don't jump on the wagon right away. Sometimes we have to agree to disagree and then just walk away..........
