One of the biggest problems in our planet is overpopulation. Last few centuries the world’s population is growing faster and faster. This time per annum population increases about 77 million. Now is predicted that in 2050 in Earth will live 9.5 billion people and that biggest population growing will be in less developed countries. The biggest overpopulation problem is that Earth will not be able to supply all people with basic necessities like water, food and energy.
