rhickman,
Your comments on DDT are very interesting. Several months back, I watched a show (Discovery channel?) that went over the DDT controversy - and surprise! Current info indicates that DDT wasn't all that bad after all. Given the increase in mosquito-vectored diseases like West Nile virus her in the states, and the continuing problems with malaria etc in undeveloped countries, a serious argument could be made that the anti-DDT campaign actually COST lives.
I think you guys should be a bit more careful in slamming somebody like FATCAT just because his viewpoint doesn't match yours. Disagreement DOES NOT necessarily equate to ignorance, if you think it does then you haven't done much debating or studying. Perhaps it is his mode of expression (style) that bothers you more than his actual comments? No need to slam him.
As far as the risks of diesel exhaust, in general I suspect any human would concede that cleaner air = better quality of life. However, it is not so obvious exactly what components of pollution merit the most attention. Just about everything we humans do ends up polluting or changing the environment. Trivial example: people love that "new car smell". That smell is actually the outgassing of plastics etc in the car, and those vapors are in no way, shape, or form "good for you".
We put fluoride in our municipal water supplies, as the prevention of cavities is considered to be worth the introduction of a minute amount of poison. Reasonable? Probably, but the fact is that such systems are typically introduced with little or no public debate, "Just because we say so. " Take your kids to public school, and you WILL get them vaccinated. What if you are one of those old-fashioned folks that thinks the natural immunity from suffering through the milder diseases like chicken pox is desirable, and don't want your kids vaccinated? Tough, you do it "because we say so" or take your kids elsewhere.
When we were 5 years old, the "just because" answer from Mom and Dad didn't satisfy us. Why, as adults, is it so horrible for people to question the rulings that are impressed upon us?
As far as pollution goes, the only way to improve things is to get people to ZIP IT UP and quit flocking together into cities. People like to congregate like grackles in a pecan tree, and just like the birds we leave a huge sprinkling of our filth and byproducts under the tree. Go to the Middle East, and you can easily spot the location of ancient cities by the presence of a large artificial mound known as a "tel", as in Tel Aviv for instance. Good examples abound, at Meggido, Jericho, etc. Why is there a hill? Because the people living there over the centuries literally built their city upward millimeter by millimeter, year by year, upon their own trash and waste. Thousands of years later, people in the big cities are still repeating that process - looks like we haven't learned much.
In the 1800's, the USA operated on steam and flame. Household and industrial heating / cooking denuded entire forests, and put the cities under an endless pall of smoke and soot. Our air today is far cleaner, our water tremendously purer, our food cleaner, in fact things are much cleaner and nicer in just about every way. Bring those guys forward in time, and they would be astounded by the simple act of getting clean, disease free water from a faucet anywhere, anytime, with quality that even a king couldn't have enjoyed in their time.
Is there still room for improvement today? ABSOLUTELY. But what improvements are worth the extra money? For people in the cities, low sulfur might be critical. But why should the rest of the nation have to switch over too just because there are so many people who want to live in a big soup bowl of each other's emissions and byproducts?
Questioning EPA policies does not signify ignorance, it signifies suspicion (and perhaps, cynicism). Considering history and the often-suspect motivations of our fellow men, perhaps there is justification for both.
