The biggest and major problem is rapid increase in the number of people. If the world population continued to grow at the current rate, the earth would not be able to sustain its population and the number of people will decrease. Another problem is shortage of resources. For instance, when the numbers of people increase absolutely the resource will exhaust like water and crops. Another problem is standard of living. The main problem in the world is high cost of living and if you don’t have money you can't live in this world. For example, in the poor countries a lot of people are die because of they didn’t have the fundamental sources such as water, food and health care.
There are several things we can do to solve the problem of overpopulation. One solution is increasing people's knowledge. All societies should know that low population are currently enjoying the greatest advanced and rises in living standards such as the health, food and education. Another solution is number of birth. When we have control at number of birth we can sure that overpopulation problem will be limited and we can solve it.
In conclusion the overpopulation is huge problem and we have to worry about this rapid increase in it. In my opinion population growth will decrease if we follow these solutions. The population growth is a huge problem and I hope we can solve it.
