Environmental Health: Issues and Human Concerns - Chapter Summary and Learning Objectives

Many man-made factors in our environment, such as air and water pollution, greenhouse gases and hazardous waste, have created serious threats to human health over the years. The lessons in this chapter look at these environmental problems, their impact and what can be done to rectify these conditions. By the end of this chapter, you'll have an understanding of:

  • Types and causes of pollution
  • Greenhouse gases and the greenhouse effect
  • Types of hazardous waste
  • How we can reduce solid waste
  • Water conservation methods
  • Future environmental issues
