Yeah, maybe it is environmental. I don't know. A lot is changing now.
The thing about nature balancing itself out though.....I mean, I think that would probably normally be able to happen, but....I don't think it can without us replenishing the forests to what they once were. Most of the world was forested just a few centuries ago, and now there are hardly any left. I believe this is why we have the global warming problem in the first place. I mean, I suppose we would still have that problem anyway, just because of the things that we do that put out extra CO2 in the air, but....since it is the trees that convert CO2 into Oxegen and we have more CO2 than normal and significantly less trees than normal, well....
I think for this one, we need to step in. There isn't enough nature left for nature to do it alone.
And (on a side note) those "Summits" that the politicians have every once in a while to "try" to do something about Global Warming and CO2....since they started having those...the CO2 in the world has gone up 41 percent. I think the German satire show I like to watch said they just go there and play Parcheesi or something. Haha! Sure looks like it ;-)
