Bjorn, I would say things like catalytic converters and so forth are more to due with the reduction in pollution. I would not count CO2 in the same respect. I completely agree with the general push for reduction of pollution. Cleaner air/ water is better for all concerned.

I also think we should look at alternative energy sources a lot more than we are now. I just do not want to due this because of global warming concerns. For me, it is more a legitimate geopolitical and self sustaining interest.
