Well, as you said, it seems that global warming is a fact, and yes, there is certainly disagreement as to the cause(s) of same. I look at it like this: There are all sorts of reasons to think that exhaust and effluent from motor vehicles and industry is not good for us. It smells bad, it causes all manner of diseases from respiratory distress to cancer. Personally (and I know this is highly unscientific, and likely proves nothing) I find it hard to believe that pumping as much of that shit into the atmosphere and into our various waterways as we do can be good for the planet. I recognize that nature has this amazing ability to clean the crap that we spew, but it does appear that we've long since overdrawn on that account. Whether or not our industrial and transportation activities are the primary cause, one of many causes, or only a small contributor to global warming, it seems a good idea to cut back on such pollution as a health consideration for life on this planet. In addition, there's the fact that fossil fuels are a finite resource. We seem not to be able to come up with acceptable replacement technologies fast enough, so if we're not able to cut down on our reliance on them, we're simply going to run out. That won't be pretty. I know there are those "experts" that tell us that we don't have to worry about global warming, that it's not a human phenomenon, that it's all overblown. I also know that there's no "democracy on truth", and that we can't play a numbers game in terms of how many "experts" say what. That being said, it does seem that the majority of scientists that speak out on the matter tell us that global warming is a fact, and that human activity is a major contributor to it. This reminds me of the so-called "evolution versus creationism" debate. Most respected scientists come down squarely on the side of evolution as a fact (not a "theory"), but there are a very few that tell us that evolution isn't possible and that the world must have been created just as the Bible tells us. I know what I believe in both of these matters: The human race has evolved from stupid monkeys into brilliant opposable thumb brainiacs who are stupidly spewing shit into the environment that will cause the world to burn to a crisp in a few generations. I could, of course be wrong, but I'll take a chance on trying to clean the air and the environment. If it doesn't stop global warming, I still believe that we'll all be better off for it... cheers, frank -- "Sharpness is a bourgeois concept." -Henri Cartier-Bresson -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
