The best way to solve overpopulation is through birth control. Birth control may involve implementing policies that limit couples to only one or two children and encouraging family planning.
Today, the world has more than 7 billion people, and the number is increasing daily. Overpopulation has many effects including environmental degradation, high cost of living, high unemployment rate, increased conflicts and deterioration of resources. To avoid these effects, the best solution is to control human population, which can only be achieved by making family planning information available to all people. Some countries, such as China, have restricted couples to only have a certain number of children.
