CAR, I was only concerning my argument with the economic benefits of AB32. Now there are arguments to be made for other benefits, but I find these arguments limp at best.
CO2 (what we exhale) has no direct effect on health, quality of life, or anything else. There is a tenuous link between anthropomorphically produced GHG’s and global warming, but that discussion is for another day.
Now pollution does have an effect on those things and if you believe we should reduce pollution. Let us do it directly, by regulating or taxing pollution.
