Human Impacts on Biodiversity & Ecosystems - Chapter Summary

This chapter covers different types of pollution, including biological, chemical and physical pollutants. Different types of water and air pollution are discussed, as well. Additional lessons show how humans cause the extinction of animals by destroying or greatly changing their habitats.

As you continue, the concept of deforestation and its effects will be introduced. You'll read about the human contribution to global warming and what conservationists are doing to slow and even reverse the damaging effects humans have on our planet. Once you have completed this chapter, you should be able to:

  • Define and identify biological pollutants
  • Differentiate between groundwater and surface water pollution
  • Identify the six air pollutants classified by the Environmental Protection Agency (EPA)
  • Understand anthropogenic pollution
  • Recognize the problems associated with deforestation
  • Describe the three Rs used to reduce solid waste
  • Explain how land conservationists fight land degradation

Deforestation is the clearing of trees without the intent of replacing them or reestablishing a stand of trees. Learn reasons for deforestation and discover the consequences of this process in all forests, including tropical forests.

Fossil Fuels, Greenhouse Gases, and Global Warming

6. Fossil Fuels, Greenhouse Gases, and Global Warming

In this video lesson, you'll learn what roles fossil fuels and greenhouse gases play in global warming, as well as what life on Earth can expect due to rising carbon dioxide levels within Earth's atmosphere.

What Is Conservation Biology? - Definition & Principles

7. What Is Conservation Biology? - Definition & Principles

Conservation biology aims to reduce the human impact on the environment by looking for the causes and possible solutions to these problems. In this lesson, you'll learn about conservation biology and the different types of conservation.

The Endangered Species Act & The World Conservation Strategy: Goals & Purposes

8. The Endangered Species Act & The World Conservation Strategy: Goals & Purposes

In this lesson, you will learn about the Endangered Species Act, an environmental law that protects endangered species. You will also discover how the ESA works and how species are protected under it. Finally, you will learn how a World Conservation Strategy can help endangered and threatened species worldwide.
