This is what bothers me about the environmentalist nazis that condemn the U.S. at every turn and roll out 16 year old kids to lecture us on climate change. I'll get on board once every other nation matches the United States' federal/state/local funding (as a % of GDP) for "the environment," as well as all of the private donations that Americans give for these efforts. (Again, use percentage) I doubt there is any other nation spending, anywhere near, the federal and private dollars on R&D, technological advances, and product improvements that we do. Once Russia, China, India, Brazil, Mexico, etc are on board, then we can talk about what more the United States can do.
