About This Chapter

This chapter looks at how human beings have affected the environment at the global level. These lessons provide an outstanding study resource for the NES Middle Grades Social Science exam.

NES: Impacts of Humans on the Environment - Chapter Summary

Humans have modified, adapted and attempted to control their environment since the dawn of our existence. In this chapter, we examine the impact that human actions have had as technology and its demand on natural resources has increased throughout the world. The lessons cover the following:

  • The IPAT (impact of population, affluence and technology) equation
  • Deforestation and desertification
  • Environmental impacts of the industrial and agricultural revolutions
  • Industry and technology in the emerging nations
  • Industrial ecology and pollution
  • Eutrophication
  • Major greenhouse gasses and the enhanced greenhouse effect
  • Depletion of energy and mineral resources

One of the time saving features of our video lessons, in addition to their brevity, is the timeline that enables you to replay only those sections that you want to repeat. You can use the timeline to select specific segments for review without having to play the entire lesson from the beginning. Then you can take our self-assessment quizzes to reinforce your knowledge and retention of the lessons and measure your progress.
