OVERPOPULATION

For years people have worried about the problem of (1) .......................... Overpopulation happens when an area is filled with an (2) .......................... number of people. This causes a (3) .......................... of the resources in that area. Some people argue that the earth is already overpopulated, with over (4) .......................... people on the planet today.

Now, however, some people say that the main problem is not overpopulation. Instead, they see that the real problem is (7) ..........................

Some argue that overconsumption, not overpopulation, is what will lead to the (9) .......................... of our planet and the (10)            .......................... of our resources.

Exercise 6: Read and decide if each statement is true or false or not given.

OVERPOPULATION (CONT)

These two problems are related, but they happen in different parts of the world. Overpopulation tends to be a worse problem in poorer countries where people rely more on farming and often have larger families to help with the workload. Overconsumption is a much worse problem in the richest countries in the world. The reason for this is simple. When people have more money, they use more resources. For example, look at carbon Missions. This is the amount of carbon released into the atmosphere based on the energy people use by doing things like driving a car, riding in an airplane, or heating a house. The carbon emissions of one American today are roughly equal to those of four Chinese, 20 Indians, or 250 Ethiopians. It is basic math that if the rich continue to use the earth’s resources at this pace, one day those resources will run out.
