Nature: The Planet May Be In Trouble If China Controls It's Air Pollution.

11. Thanks. It does.

I've been very concerned about fracking (and the specious use of the term "clean energy&quot for all the other general and specific reasons you pointed to. I was not aware of the greenhouse cooling effect of particulates...even though it is right in front of my eyes.

I share your frustration with the misunderstandings resulting from the public's relatively limited knowledge. I was humbled to learn that reforesting in some areas may have a negative effect...that is the reduction of reflectivity from snow cover.

Somewhat off topic, how many people can this planet sustain with current technology? And I ask that with an underlying assumption that we largely supplant fossil fuel use by employing as much renewables as we can and as much nuclear power as we have to in order to severely reduce greenhouse gas emission from energy production. It seems our energy production is only part of the problem with the rest being what it is that we do with that energy.
