It "oxidizes" the pollutants leaving you with fresh O2 to breathe and no smells!

And it is immoral to dictate how another should use their property Then why are there zoning laws in every city and town, and laws dictating how to treat animals and disallowing pollution and so much more?

China -no one trusts their numbers, heavy pollution and heavy smokersItaly - largest population of elderly - this with highest risk.We can't get too hung up on stats because of testing.

I agree with your friend to get all legal mumbo jumbo about its legality and what you must do to correct it and any known or unknown and known pollution and what you'll have to do to cure it. 

That's humorous, "I only use light curry on an infrequent basis".Like a manufacturer promising they will only pollute the environment slowly over a long period of time.

Power plants have many scrubbers and devices to recapture both the energy and the pollution to clean it further before emitting it.

But here is too cold and polluted. 

There's no noise or light pollution. 

Once people smell the air, they'll all pollute it in efforts to not get stuck in it.There'll be a short term rebound for everytime the news mentions the Fed's interference, but there's more depth for this to be to hit.

I love getting stuff on the market place (ex: cabinets, fridges,etc) and giving it, it's 2nd life in a rental, and less pollution!
