Doesn't that add to pollution, RobDale? :>)

I find myself in agreement with Kim C. There is just too much good evidence on both sides to really know which is right.

I referred earlier to the Fox News Network show when they were featuring a debate on global warming. There were to "experts" on the show. One said global warming was a real threat, and the other said it wasn't. Both had good credentials and about all they did for the whole show was disagree with each other.

That doesn't mean that we shouldn't be environmentally responsible, of course, but maybe for reasons other than the threat of global warming.
