How Big is a Crowd?

The Great Lakes and the surrounding land provide many resources for the people who live in the area. Water for drinking and industry, fish for food, minerals, and other resources are abundant. However, people change the landscape. They create wastes and add chemicals to the environment when they use resources, and these can be harmful. When many people are concentrated in one area, they may compete for resources. In addition, the wastes these people generate tend to concentrate in the area immediately around them and may cause pollution problems.

Objectives

  • Compare the relative sizes of the five Great Lakes and their human populations.
