Many people, in and out of China, believe the One Child Policy is an infringement on the human rights of couples in China.
The policy led to civil and political un-rest in both China and the rest of the world, due to the apparent bribery for couples to stick to having only one child. The restrictions of the law are believed to be un reasonable and 'ridiculous'.
Couples under 25 are not allowed to have a child, and if a woman under 25 gets pregnant then abortion is heavily encouraged by both Chinese society and the Chinese government.
The inconsistancy of the law (with many families being granted exceptions) caused a lot of controversy within China, leading to civil unrest.
