I agree the problem has more than one aspect, but we made real progress that we are now backtracking on nationally. Local problems will always be local. Go to a <insert industrial town here> town and they will likely be pro that industry but as a nation we recognized local pollution didn't stay local and created things like the EPA and implemented regulations that worked. Now we are backtracking because, I think, people haven't felt the problems themselves. I remember burning eyes and amazing sunsets, others don't. How can we get those that never experienced inoculated so they will keep the regulations that made things better?
