The PRC is polluting as much or more than the west did in the 50s....which was a LOT....LA used to have over a hundred days a year where "smog alerts" would be issued, now few if any...in the 60s hundreds of New Yorkers would die in a single day because of smog....London in the 50s was horrible, THOUSANDS died....that sh**t don't happen anymore. Unless you live just downwind from China or other similar hell hole. We learned our lesson and started cleaning up 40 years ago and while far from perfect, we're doing much MUCH better. Everybody else has the same information we have, but they don't care (enough to do anything about it).
Except I didn't say we should do nothing or call it a lost cause. I said "we should do what we can".
There are a lot of things wrong with Cap n Trade. From protectionist nonsense (Euro steel and cement factories aren't held to the same standard other industries are......why? to protect them from other countries steel and cement industry that
doesn't have to live under cap n trade rules), if it's effective and cuts the use of CO2 emitting sources in the west the price will drop, the now cheaper coal is still going to be used, it will just be used in places withOUT the environmental protections we have in the west. Wouldn't you rather have coal used in a place that will at least scrub the output enough to keep us alive versus a place where there are NO restrictions at all? Of course it would be better to leave the coal in the ground, but we can't do that yet for various reasons, not the least of which is greenies keeping new nuclear power plants from being built.
