First, a lot of people can't get employment, which is a universal problem in the world. Second, in developing countries there are not enough shelters for too many people and so some people are not properly housed and even are exposed to the elements. Third, in underdeveloped countries a lot of people suffer from hunger because of food shortage, which in turn causes many other problems, malnutrition, disease, etc. Fourth, there are not enough schools for so many people and so a lot of people are illiterate.
Therefore, to eliminate these problems, human beings should take effective measures to control population.

The two charts show that the increase in the U.S. population has been accompanied by a corresponding decline in the number of wildlife species. Far too many species have been lost already. This poses a danger to ecological balance.
As the human population expands, more and more wild animals are hunted for food, or because they are thought to present a threat to man. But studies show that one of the primary causes of the disappearance of wildlife is pollution, which is one of the consequences of population growth and economic development. This makes us wonder if man is able to share this planet in harmony with other life forms.
In my opinion, it is imperative to take steps to reverse the disturbing trend illustrated in the charts. One measure would be to forbid the building of cities in areas where wild life is threatened with extinction. But, more imporantly, man must learn to stop polluting the environment, or he himself will become extinct.
