I am left wondering why China is making all of these "green" changes; more renewables, planting trees at the edges of deserts, etc. I mean, I guess it could be altruistic, to help the Earth and it's people. However, I just don't see that kind of attitude coming out of China. So, again, I am left wondering what their angle is. Is it simply to "stick it" to the United States?
What is everybody's opinion on this?
Because it's good for China to have less desert and more forest. It isn't a very complicated question to answer.
I think the real question is the other way around; why isn't the US the world leader in this?
China's answer is fairly straightforward - jobs, exports, energy independence, wind/solar is cheaper, and they have 1.3B people who don't want to live in a big polluted desert.
Why don't you see that attitude coming out of China?
Because China wants to rule the world. That includes roughly being seen as a great bastion of awesomeness.
The huge solar rollout is very much because China thinks it might end up in a war, and they are currently very vulnerable to a blockade for energy resources, and grid scale solar is unblockadable for like 20 years. You can bomb it, but that's a hard mission.
If what I believe is correct, there would also be evidence of China creating unblockadable food transport lines and relationships.
Global Warming is well understood all over the world. China doesn't want the world to suck right before they finally undo their Century of Humiliation and retake their "rightful" place as mega empire that exports culture and tech and power. They want to be the super power ruling over an awesome world, not ruling over ashes.
I've heard arguments that China has fairly limited "Soft power", and they really want to fix that, which takes actions that at least look altruistic and win-win.
With the US self-defeating, China is in a great place to be the leader of a stable world, and even be a counterweight to an abusive USA.
Most of China's large projects are actually some type of competition with the US. The Tianjin Grand Bridge was basically built to eclipse the Causeway and showcase China's engineering prowess. The massive Shanghai subway buildout was a direct challenge to New York City's subway hegemony. Those 20+ story pig towers? Totally unnecessary way to do farming, but a source of national pride when compared to the already impressive scale of US factory farming. China is building record numbers of both solar and coal plants, which seem to be at environmental cross-purposes, but it makes sense when you consider they are trying to beat the US at both clean AND dirty energy. It's in the five-year plan.
