Unit 1: What Is Air Pollution?

Clean air is a mixture of nitrogen and oxygen, with less than 1 percent carbon dioxide, argon, and other gases—along with varying amounts of water vapor. Even small amounts of particles and gases, called air pollutants, that are not part of this normal composition can cause us serious health and environmental problems. Air pollution is a problem in many areas of the United States. It can damage trees and lakes, and make people and animals sick. It can also damage buildings and other structures. Air pollution can cause haze, reducing visibility in national parks and sometimes interfering with aviation. The federal government regulates air pollution in order to protect human health and the environment.
