Ch 17: Biodiversity & Environmental Issues

About This Chapter

Let us help you learn more about the environmental issues the planet Earth faces as well as the subject of biodiversity with this chapter. Use these lessons to prepare for a placement exam or to test your knowledge of the subject matter. You can gauge your knowledge by using our quizzes and chapter test.

Biodiversity & Environmental Issues - Chapter Summary

Our instructors outline conservation biology and the related studies of habitat fragmentation, factors affecting global warming and climate change. You will read more about air pollution and how to control it, as well as other types of pollution such as noise, radioactive and water pollution. The importance of the ozone layer and how humans are contributing to its depletion will also be introduced.

As you continue through the chapter, the study of bioremediation and how bacteria are being used to clean up pollutants is discussed. This chapter will prepare you to do the following:

  • Describe how conservation biology works to reduce the human impact on the environment
  • Define habitat fragmentation and metapopulations
  • Explain the human and natural causes of global warming and climate change
  • Detail the connection between air pollution and the ozone layer
  • Differentiate between water, noise and radioactive pollution
  • Give the definition of bioremediation
  • Outline the causes of deforestation and species extinction

Our study materials are designed by instructors who know how to make the learning process enjoyable. Take the lesson quizzes and chapter tests to see how well you know the subjects and where you might need to focus more of your attention. Utilize this chapter for review at any time on a mobile device, tablet or computer. If you have questions, our instructors are available to lend a hand.

What Is Conservation Biology? - Definition & Principles

1. 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.

Conservation Biology, Habitat Fragmentation, and Metapopulations

2. Conservation Biology, Habitat Fragmentation, and Metapopulations

It's becoming harder to conserve large, unbroken tracts of wilderness. Is there another way for conservation biologists to ensure the survival of a species? In this lesson, you'll learn about habitat fragmentation and metapopulations.

Global Warming: Atmospheric Causes and Effect on Climate

3. Global Warming: Atmospheric Causes and Effect on Climate

Global warming is a multifaceted, complex issue. It involves both natural and human causes that can increase the amount of greenhouse gases. This lesson looks at some of the facts about global warming and how they could contribute to climate change.

Factors Involved in Climate Change

4. Factors Involved in Climate Change

Our Earth's climate has changed many times in her 4.5 billion year lifetime. Discover the multiple factors that influence these changes and test your understanding with a short quiz.

Global Climate Change: Effects and Mitigation Strategies

5. Global Climate Change: Effects and Mitigation Strategies

In this video lesson, you will learn about the potential effects of global climate change. You will also learn how some are working to better understand climate change in order to slow the rate of temperature increase on Earth.

What Is Air Pollution? - Definition, Sources & Types

6. What Is Air Pollution? - Definition, Sources & Types

In this video lesson, you will learn about the sources and types of air pollution. You will be able to identify the six classes of air pollutants identified by the Environmental Protection Agency and the Clean Air Act of 1970.

The Ozone Layer: Importance and the Harmful Effects of Thinning

7. The Ozone Layer: Importance and the Harmful Effects of Thinning

In this lesson, you will learn the importance of the ozone layer and how it is depleted. You will also study the research and policy that has been instrumental in its recovery.

Controlling Air Pollution: How Developed & Developing Nations Differ

8. Controlling Air Pollution: How Developed & Developing Nations Differ

In this lesson, you will learn how air pollution is controlled in developed and developing nations. You will also learn about the U.S. Clean Air Act and how it has evolved over the years to address air pollution in the United States.

Water Pollution: Definition, Types, and Sources

9. Water Pollution: Definition, Types, and Sources

In this lesson, you will learn about the different types and sources of water pollution. You will gain an understanding of both surface water and groundwater pollution and the similarities and differences between them.

Noise Pollution: Sources, Effects & Control Methods

10. Noise Pollution: Sources, Effects & Control Methods

Have you ever rolled down your car window only to hear several different noises? The sources of the noises that you hear can contribute to noise pollution. Use this lesson to learn about noise pollution, its sources, and the different ways to control for it.

Radioactive Pollution: Definition, Sources & Prevention

11. Radioactive Pollution: Definition, Sources & Prevention

This lesson defines radioactive pollution. Then you'll learn about its possible sources and what harm radioactive pollution may bring to a person, as well as the ways by which it can be prevented.

Bioremediation: Microbes Cleaning Up the Environment

12. Bioremediation: Microbes Cleaning Up the Environment

Bioremediation uses living organisms to clean up pollution. In this lesson, we will examine the role of microbes in bioremediation and why it is not a perfect solution for degrading environmental pollutants.

Deforestation, Desertification & Declining Biological Diversity

13. Deforestation, Desertification & Declining Biological Diversity

When trees are lost due to deforestation, the result can be a drier climate and desertification or the transformation of the once fertile land to desert. Learn how deforestation and desertification can lead to a decline in biological diversity.

The Causes of Species Extinction

14. The Causes of Species Extinction

What do dinosaurs, passenger pigeons, and a species of Australian rat all have in common? They have all gone extinct. This lesson will examine the causes of species extinction from mass extinctions in the past to human-caused extinctions today.
