The big problem which is being faced by developing countries is overpopulation. Severe impact has been posed on the environment by over population. Overpopulation has to some disastrous happenings such as certain species of wild animals have been extinguished and forest has been destroyed. Government has to take measures in order to prevent over population. Nearly sixteen thousand hectares of forest has been chopped down in the beginning of every year. The pathetic news is that nearly five million people die due to illness. Government has to conduct some program and tell the people the effects of overpopulation. Overpopulation is also a cause for the pollution. As the population increases the level of pollution in all fields also increases. The depletion of ozone layer is also a problem. Scientists have said that the use of CFCs has increased to a large extent because of over population. Human beings have started to clear all the forest and build houses for their shelter. There is no adequate fresh water available for us to drink. Care should be taken to save fresh water. Starvation and mal-nutrition are the other problems faced due to overpopulation. This issue has to be solved very quickly before it turns into a serious problem.
