Yes. I cant help thinking about the US is letting out 30-40 TONNES of mercury in the air, every year from coal burning. I'm also thinking about EnCana, because all their heavy equipmentand and trucks runs of NG. I dont think anybody like, benzene, cloride, organic compounds what ever their names are, to be in the air they breate, so fine if they can find a solution. I think the NG industry wants to appear as a clean industry and if held against coal dont you think NG could win still? Well, I think that even against some so called "clean tech" or RW, NG could win or get even? And yes, if cars began to run on NG this would ad to redusing CO2 and lead amoung other. I dont know, but it seams to me that focus is very much on CO2 and not that much on heavy metals and maybe pesticides, pesticides from agriculture and spray fluids, propellants including from aerosol, these cans pollute and global it ads up, but maybe it's me, anyway I think the CO2 focus is a little too heavy. Buy a bit more rainforrest:)
