||Chapter 10 Environmental Health
Earth's living things must share the resources of the planet and maintain a delicate balance. Pollution can upset this balance.
Air pollution--outdoors as well as indoors--harms the environment and people's health.
Pollutants can contaminate Earth's resources, including its water. By practicing conservation and disposing of chemicals carefully, people can help protect these resources.
Land is a precious natural resource. Precycling, recycling, and careful waste disposal are three strategies that will help protect the land.
Energy conservation helps protect the environment and preserve natural resources. A quiet and visually pleasant environment contributes to people's health and well-being.
