Graham, I assume that when folks talk about affecting the economy they are referring to the cost of implementing the safe-guards necessary to meet very stringent (or more stringent) environmental standards.

Also, if the United States is the only source of pollution in the world, I'm not aware of it. Seems to me I have read that China and other countries have a problem with pollution too. It wouldn't surprise me to learn that our country produces more pollution from industry than any other country, because our country is a leader in manufacturing goods.

Thosp: I prefer women. However, I am concerned about the environment, and I recycle, don't drive a gas guzzler, etc. I'm probably not as rabid about it as is my friend kat, though. Anyway, most of the trees here in the desert have thorns on them.
