Dangers of Overpopulation


The world’s population is growing by almost 80 million people every year. We will be facing many problems in the future:



  • More and more people need room to live. They are taking away the living areas of animals and plants.
  • Cities have problems making enough drinking water for thousands of people who want to start a new life there every year.
  • Population in rural areas is growing too. People need more food and have to grow more crops on the same land. This means that the quality of the soil is getting worse and worse.
  • More and more trees are being destroyed, especially in tropical regions. More carbon dioxide, which is usually taken up by trees, is now set free into the atmosphere. This leads to global warming.



Population growth is highest in developing countries. Young people have to care for their parents and grandparents, so they have less money to buy the things that they need. They stay poor.

Africa is the fastest-growing continent on earth. But its people are getting poorer and poorer. Every third person in Africa doesn’t have enough to eat. The average African family has about 5 children.



Food and Water


The “ Green Revolution” of the 1960s and 70s has given farmers better methods and tools to grow crops and food. But ,still, they cannot produce enough to feed the growing population. Food will get expensive for these countries because some of them have to buy it from industrial countries. Many people die of starvation and millions more will die in the future.

In addition , about 400 million people all over the world live in places where there is not enough drinking water.



Many Third World countries have a high number of children or young people. Unemployment will be going up over the next decades, because the governments cannot create enough jobs to give work to its younger generation. Young people who can’t find any work sometimes try to get money by stealing, dealing with drugs or doing other illegal things. This might lead to social unrest in such countries.
