I'm pretty sure spartymack isn't opposed to cleaning up the environment, he has stated several times he is for it from what I have read.
He brought china into it because they are probably the biggest environmental threat currently. At this point, any efforts to curb pollution in the US, while valid, will result in only minimal impact on the environmental spectrum.
Again, not saying the US should not continue to improve their impact; however, when looking at where environmentalist should apply the greatest pressure in order to yield the greatest percentage improvement to the environment, china must be targeted.
Zoom's link to china shows where a huge global concern is, yet china is not being forced to clean up their shit. This planet is under attack by far worse places than the US. It is time to refocus and apply pressures where it matters most. Again, I'm not saying the US cannot improve its pollution levels, but I think most already are working toward those improvements. Meanwhile china and others literally don't try at all.
