China's pollution problems are no worse than ours were 40 - 75 years ago. They can address those issues just as we did and they do not have to invent the technology, its already been done.
China began taking very aggressive action to address their population issues decades ago and today their population growth is centrally controlled. In China you do not get to choose how many kids
you have the State chooses for you. So going forward they are much better positioned relative to population management that we are!
Lack of water
? China is just completing the largest dam project
the world has ever seen, the Three Gorges Dam. This reservoir will stretch over 600km upstream! They are also aggressively pursuing many other water conservation and control efforts. China will not be lacking in water.
Lack of arable land? Not with the water management efforts as outlined above. China has never suffered from a lack of food
production and the rapidly accelerating industrialization of their agrarian economy will net dramatic increases in their food
producing capabilities over coming decades.
Violent revolution? An unarmed and pacified population is generally lacking in success when it comes to armed revolution. Toss in the fact that the Chinese Govt. can take whatever action it wants with no fear of meaningful international intervention and I wouldnt bet on the current
Chinese Govt. being overthrown through armed internal revolution anytime soon. Or ever for that matter.
I am not saying that China will dominate the planet next year. Such fundamental shifts in global power do not happen overnight. While the 20th Century is remembered as being dominated by the USA, this nation did not rise to a position as a true global power until the 1940s. China too will suffer growing pains and challenges.
But the fact is they are far better positioned to overcome their challenges than we are to overcome our own. The coming collapse of the US monetary system will crush the fiscal foundations this nation is built upon while simultaneously destroying global trust in our fiscal leadership. No longer will the dollar be king and no longer will the planet blindly accept irrational levels of US debt.
