Kyoto offered the US a chance to have its economy wrecked. The politicans both liberal and conservative have rejected it due to its dire economic impacts. No one could ever expect the US to buy into such a treaty. The treaty should be redone so that the economic impacts are mitigated thus allowing the US to sign on and to start addressing the CO2 problem.
I agree that smog kills and that the effects of fossile fuels are causing significant loss of life in large cities. I would also point out that hardly anybody really cares. I consider myself to be an environmentalist and I have always driven small cars and lived in small homes (my wife complains all the time because I can afford a larger home). I am also a conservative (a former liberal but the lying and taxes changed my way of thinking). I recently attended a forum addressing enviromental issues and when I pulled in the parking lot I was amazed by all the huge SUVs. The meeting turned out to be a liberal gab fest and afterward they all got in their SUVs and drove off feeling good about themselvs. Not one person congratulated me for taking the issues seriously.
As for those who believe that that there are alternate energy and fuel sources available, but have been "hidden" due to all the policital lobbies on both sides of the border in Canada and the US I would submit that there is a finite amount of energy in a gallon of gas and that it will only push a 5000 lb vehicle so far and that it will push a 1500 lb vehicle alot further. Some gains can be picked up on the margins (fuel injection, electronic ignition for example) but the limit is the amount of energy in the fuel. There is no magic bullet that big oil or big auto is hidding. I suggest to those that want to reduce fossile fuel use the best place to find the cause of the problem is in the bathroom. I suggest you go in there and take a look in the mirror.
Also it should be noted that distilling ethanol can be accomplished by cooking the stuff off with farm waste or wood waste both methods are considered CO2 neutral.
A couple of links to the new technolgies in the energy field are provided and they are not being bought out by big oil or big auto.

Also I had the pleasure of surving time in the military during the war in Tampa at Central Command. Like many other military personnel I don't mind the risks of being in combat. The only thing that bothered me was the whinning. The liberal whinning about the war goes on with the death of each solder bringing comparisons to Viet Nam. The truth is these people are politizing the issues the same as they are politizing the enviromental issues. If they really cared about people being killed and mamed they would be screaming about the 40 thousand plus people killed on the highways and the 120 thousand that are badly injured each year.
