This strikes me much like a personal hypothesis that smoking is not harmful. It's a fine theory to have in your own home, but when you apply to your theory next to a daycare folks will be more upset.
There's the skeptical professor from the BerkleyEarth project who was doubtful about many aspects to the science, but when we looked at it in detail became concerned enough to devote all his time to the problem. http://berkeleyearth.org/. His opinion, after studying it for years along with research assistants, is that it is happening, man made, and probably a very bad thing for many, many people on Earth.
I think what frustrates a lot of folks is that there seem to be many people hanging around daycares smoking saying that they don't believe it is hurting anyone, while the US Pediatrician Organization, WHO, etc, etc all say that second hand smoke is bad, causes asthma, etc, and the only way to convince anyone seems to be waiting 5, 10, 20 years until all the consequences are apparent (and irreversible).
I'm sure that you can still find a doctor who says smoking is good for you and those around you, but the consensus is that is has a lot of negative externalities that other people bear.
Thanks for replying so many days after this thread started, seems like you care enough to say something. It's gratifying.
I can't tell if you are equating "pollution is bad" with "earth will become uninhabitable". Are you?
I agree 100% that pollution is terrible, and we should curtail it where we can without slowing down our technological advancement as a species too much. That's simply the responsible thing to do, and anyone that disagrees should visit China's big cities and take a deep breath or go swimming in some algae plume ocean water.
But, the mental leap to "imminent planet death" caused by us at our current technology level is too far a leap for me to take. The world and its systems are just too huge and humanity is too insignificant and primitive.
I contend the system is complex and we don't have adequate models to simulate it. And, the system is robust and can adjust to and absorb much larger disruptions than mankind can currently create.
