Human Overpopulation
The sharp rise of world population growth rate is the current situation. An important symbol is the short time of population expansion. The world population increased from 5 billion to 10 billion using 200 years while it increased from 10 billion to 20 billion using only 100 years. It is clear that the resources on our earth are limited, that means more people would consume more resources. Thus, one day, the resources would be run out of, and our planet would be destroyed earlier.
The reason for this rapid population growth is the improvement of living conditions and medical technology leading to the reduction of death rate. The life expectancy continues to increase, which is the main reason for the overpopulation.
Currently, there is more than 50% of the world's population which is under 25 years old, the structure present typical growth type. It would decide the continuously growth of population in the future for a long time. As the earth's space and resources are limited, controlling the population expansion is an urgent task.
In China, the government implements a policy called 'one-child policy'. China, it is known as the biggest country in term of population, which now has almost 14 billion people living in the country. This policy was first introduced in 1978 and enacted on September 18th, 1980 to alleviate social, economic and environmental problems in China. The positive effects of this policy can be seen as the following:
- Reduce the overall population
- Change the demographic structure including age structure, sex structure and ethnic structure.
- Increase the family deposit
Whether this policy could help to mitigate the overpopulation effectively is a question.
