it's the biggest contribution china made to environment. the way to do it should be changed, but the idea is never wrong.
throughout china history, whenever there was fewer people, usually it was the better times. rulers treasure more about lives.whatever problem china have now, its better to solve it through S&T advances. aging is no big deal, only normal, we just have to adapt, work longer.
eating less pork is no big deal either, actually is better. china now need more fruits, veges, and dairy. unless tech advances fast, china will have to import a lot, as india and otehr developing nations are facing similar challenges, it's abig burden on the planet. another reason for pop control.
