The exponential population growth concerns many specialists of various scientific areas of todays. Given that, there's likely to bring undesirable and unexpected consequences to humanity and global environment. Measures such as birth control became a necessity, and as China is today's most populous country in the world (accounting impressive over 1.3 billion of people, while USA for instance, which is the third most populous have 295 million), the situation is concerning.

For that reason, drastic measures were applied to slow down the growing Chinese population. As people can't be asked or forced not to have sex, birth control has leapt from family planning to obligation of every Chinese citizen.

The so-called one-child policy is a birth control regulation that consists of a basic rule: every newly wed Chinese couple needs to sign a one-child certificate as means of contract guaranteeing educational and economic advantages for the family and specially the child if they compromise not to have a second child. Such advantages evidently may be a recurring thought on the couple's mind while having sex, forcibly to give extra attention to birth control methods. According to authorities, in principle, such measures being put in place since the 70's (although becoming statutory from last September) have already helped to prevent around 300 million of births. With such drastic problems of overpopulation and economic issues, it has proved to be a very efficient birth control regulation.

However, many people claim that such regulation override the rights that a governmental body should have on how people decide to plan their families and to have sex for means other than reproduction. According to some specialists, the one-child birth control policy had no significant impact on the Chinese population that was already experiencing a small decrease by the time of its implementation. In addition, researches proved that the desire to have a second or third child is very strong among Chinese couples.

It's important to say that the one-child policy it's not some kind of tyranny. It allows several exceptions, such as in rural regions, when the first child is a girl, the law grants the same advantages for a male second child.
