China IS overpopulated because most of the population is in east part of China....west part of China is not really populated.... The same goes with the US....it's heavily populated in the west and east of the US and not so populated in the middle of the US, which main reason....Tornado Alley. We do not need more people in the US. Look how polluted California is with all the cars and planes spewing all the crap in the air. More people doesn't mean better. It can affect their moods, behavior, etc when it gets pretty dense.
Also, one more thing to consider....many, many spieces of the animals have been disappearing or going into endangered list because of overpopulation and pollution. We do not need any more of that. Please, there's more than 300 million people in the US and growing rapidly thanks to the illegal immigrants and teen pregnancy (unwanted births)
