Global warming is part of the normal fluctuations that the earth's atmospheric temperature follows. Man's effects on earth's temperature are essentially a myth.
As for pollution, I'll stack my 1999 Explorer up against any 10 year old Honda.
So we try to conserve.
If there's such a crisis, they why are oil prices, adjusted for inflation, lower than they were in the 80's, 70's, and even the '60's? We conserve when it becomes economically beneficial to do so. Hell, oil is so cheap that we leave a good portion of our own wells shut down.
A single yuppy has more _choice_ about what to drive than a poor family.
And the majority of those that you call poor families (though the poor in the US are vastly better off than in most places in the world) climb up the socioeconomic ladder (except for those liberal welfare cases who choose not to work). Besides, having a choice in vehicles is something to strive for, not to be scorned.
Note: environmentalists have been advocating buying clunkers to crush them for years. Emission controls are lasting longer so clunkers are getting cleaner. But, commuting alone in an SUV will always be wasteful and selfish.
Well, if there were a pollution epidemic caused by automobiles, I'd agree with the "environMENTALists", but there is no such epidemic. Auto emissions are lower each year since the inception of emissions controls in the early '70's. Had you been around in the '60's, you'd know what pollution really was.
As for commuting alone in an SUV, do you think it would be more energy efficient for somebody to buy several vehicles, each with its own intended purpose (and consider the cost of production and the use of resources in this question)? Or, would you expect that a person would buy one vehicle to serve all, or as many of their own purposes as possible.
I drive an SUV. I often drive it alone. I drive it on trails; I tow with it, I commute with it, I take it on vacations (and ride in comfort, I might add). Its versatile and it meets as many of my needs as possible. And it doesn't cost that much to operate - I get better mileage with my Explorer than I did with my first car, an economical (?) 1971 Maverick!
