China's one child policy It is well-known that China has the largest population in the world, To stop the number from increasing, Chinese government brings out the one child policy as the base state policy, which became a very controversial topic since its birthday. Below is my opinion about this policy. On one hand, this policy does control this country's population effectively. As the growth rate decelerates, the pressure comes with population relieves, so does the demand for food, water and other resources. China succeeds to maintain its population and society at a stable state. However, new problems emerge while the old ones are being solved. Firstly, this policy which forbids couples from having more than one child is against human rights, obviously. Secondly, as you know, a consecutive family generation has special means to Chinese people and has been a tradition for thousands of years. So people never stop trying to have baby until they get a boy. Consequentially, the conflict between resident and official department come out and will last long. Besides, there are brutal actions while executing the policy in rural areas, which aggravate the situation. Last but not least, the potential "empty nest" phenomenon which require large amount of money to cover the insurance for old people. So, from my point of view, one child policy is an effective but crude policy. It might be appropriate under certain circumstances, but as society develops, there are other alternatives.
