Human Impact on the Environment - Chapter Summary and Learning Objectives

As humans, we have the responsibility to look after our environment. We not only have to take care of our own homes and personal environments, but we also have to look out for the larger environment around us. This means being aware of how we are causing destruction and minimizing our effects on the environment. In this chapter, we will discuss the human impact on the environment. Some of the things that you will learn include:

  • How to determine human impact on the environment
  • The problems resulting from deforestation
  • How desertification leads to a decline in biological diversity
  • The impact on the environment of agricultural revolutions
  • Environmental problems found in urban areas
  • The different aspects of pollution
