Today, the One Child Policy has been enforced for thirty-two years and it has effected China. One of the major effects it has caused is that the male-female birth ratio is tremendously unbalanced. There are predictions that there will be 24 million chinese men unable to find a wife in 2020. Another effect that will be to China's disadvantage is that there are too many elder people and a lack of youth. China's society depends on taking care of and respecting your elders. In effect, youth will not be able to take care of their family and their elders. Also, another effect of too many elder people is that there will be many jobs for people who work right now. But, when time passes there will be so many people who can't work because of their age, and a small amount of people to take their jobs because their is only one child per family.
There aren't just bad effect there are also good effects, such as more resources. Since about 400 million births have been prevented, there are about 400 million less mouths to feed. With those resources that they would have, other people are allowed to have more resources and they can be healthier. Or instead of having more, they can sell these products to other counrties for a higher price because the lack of that product. This results in more money and/or a healthier population. Since there are less people in China there is also less polution. This will benefit their crops, wildlife, and living conditions because of less contamination.
