Rainforests certainly are important for numbers of reasons.
I'm gonna put on my extrapolating, prognosticator hat on w/r/t the Paris climate summit.
No country is going to call for either a global population limit, reduction, or capping human lifetime expectancy, immediate or otherwise.
Brazil is going to say they're willing to do their part in stopping the rainforest eradication but it's going to cost the world big time.
Same with smaller countries. They're going to play the victim card.
The IMF or some other money disbursement organization under the UN umbrella is going to be looking to handle the billions which will be collected and disbursed. He who controls the money controls who it lends to.
India, which I think surpassed China in population, is going to say they're too poor to agree to CO2 limits. Maybe later. In the meantime, they're still working on getting toilets.
Russia is going to say, their country is hurting because of the sanctions and besides, their forests capture a disproportionate amount of CO2.
Some stupid, enormously expensive and impractical (as of now) technologies are going to be proposed to scrub CO2.
No one is going to say GMO's can help.
No one is going to point out any benefits from warming.
Hollywood will champion energy alternatives as they live in mega mansions, own multiple homes, get their loot bags, own multiple cars, and take private jets, while making sure no affordable housing is constructed where they live and shudder at the thought of any refugees relocated to their neighborhoods.
Of course, I could be wrong.
