It is happening now.
I have first hand knowledge that there are teams of scientists and engineers working for the EPA and closely with industries to study and develop methods for improving air quality.
These efforts are not connected with the warming crap and have to do with implementing industry specific process remedies. It is a very large effort. Since the industry is involved, there seems to be some give to assure the change is not irrational or prohibitivly expensive
That’s great to know. I never hear about that. All I hear about is how nothing is being done to clean up the smog and such. People, including myself, are so misinformed about so many things but at-least some of us try to be objective and learn the truth. Thanks.
