Human Geo (about the population)

Nowadays, the social population become a serious problem, we have almost 20,100 babies born per day. And we already have more than 7 billion of people in the world. That is a really huge number! However, more and more countries like China state a raw which is limit the reproduction of families. Such as one family can just at most get one children. Up to this, our population increase of the world can get slower. But India has not a effective raw about the population, so the rate of indian population increase get faster than China. But we need to limit our population up rate.
