Providing Clean Air

Step 1. Questions

Air pollution can make you sick and it can damage the environment. As the population grows, more people produce more pollutants. You have probably seen pictures of smog hanging over large cities. In 1970, the federal government passed the Clean Air Act to limit the amount of pollutants in the air anywhere in the United States.


For this e-journal project, you will research and write about the Clean Air Act. Here are some questions to guide your investigation:
  • What is the Clean Air Act? Find out how it was passed into law and what its purpose is.
  • How successful has it been at improving air quality?
  • What is the Air Quality Index? Research the air quality in your local area.
  • What other questions do you have about the Clean Air Act?
