Ch 33: OAE - Biology: Effects of Human Activity on the Biosphere

About This Chapter

Check out this study guide to prepare for questions on the Biology Ohio Assessment for Educators (OAE) focused on effects of the human population on the Earth. Watch our stellar video lessons and then test your skills with our self-assessments.

OAE - Biology: Effects of Human Activity on the Biosphere - Chapter Summary

These video lessons will explain how human activity has influenced the Earth's biosphere. Get to know key terms and concepts pertaining to the effects of the population on the environment. This lesson will prepare you to answer questions on the OAE Biology exam that require you to:

  • List the effects and methods of alleviation for fossil fuels, greenhouse gases, and global warming
  • Calculate human impact on the environment using the IPAT equation
  • Identify human behaviors that decrease the sustainability of the environment
  • Explain why biological diversity is being threatened by deforestation and desertification
  • Characterize influences of the agricultural revolution on the environment
  • Describe how industrial development has negatively affected the biosphere
  • Define industrial ecology and list examples
  • Distinguish between physical, chemical & biological pollution
  • Catalog different causes of eutrophication

Each video lesson has been organized by our trained instructors to make learning fun and easy. Take your time following along with the video transcripts and then test your knowledge of human impact on the Earth with our self-assessments.

Objectives of the Effects of Human Activity on the Biosphere Chapter

Instructors hoping to teach life sciences to students in grades 7-12 in Ohio must pass the Biology OAE. A score of 220 on a scale of 100 to 300 must be achieved in order to pass. Scores are criterion based, not adjusted against the performances of other test-takers.

The Biology OAE consists of five domains. The Ecology and Environment domain counts for 20% of the test. Questions about the effects of humans on the biosphere will appear in this section. This study guide will help prepare you to answer those questions. The test consists of 150 questions that must be answered within three hours. This is a computer-based test that includes only stand-alone multiple-choice questions.

Human Impacts on the Environment

1. Human Impacts on the Environment

The human population continues to grow, but the size of Earth and the resources available for our use are limited. Humans greatly impact the world around them, and our actions can and often do have dramatic and long-lasting consequences.

Fossil Fuels, Greenhouse Gases, and Global Warming

2. 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.

Global Climate Change: Effects and Mitigation Strategies

3. 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 IPAT? - Factors of the Human Impact on the Environment

4. What Is IPAT? - Factors of the Human Impact on the Environment

What do the letters IPAT have to do with the environment? Learn how this four-letter equation helps explain the environmental impact of different variables, including population, affluence, and technology.

Human Behaviors that Threaten Environmental Sustainability

5. Human Behaviors that Threaten Environmental Sustainability

The environment has a remarkable ability to sustain itself. However, human behaviors disrupt the natural environment and threaten environmental sustainability. Learn how population growth, depletion of resources, and pollution threaten nature.

Deforestation, Desertification & Declining Biological Diversity

6. 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 Agricultural Revolution: Impacts on the Environment

7. The Agricultural Revolution: Impacts on the Environment

The Agricultural Revolution was a time of agricultural development that saw many inventions and advancements in farming techniques. Learn about the Agricultural Revolution and how this period impacted society and the environment.

The Industrial Revolution: Impacts on the Environment

8. The Industrial Revolution: Impacts on the Environment

The Industrial Revolution was marked by the introduction of power-driven machinery and ushered in a time of strong economic development. Learn how advancements made during the Industrial Revolution impacted the environment.

Industrial Development of Emerging Nations and the Environment

9. Industrial Development of Emerging Nations and the Environment

Industrial development has brought economic prosperity to a number of less developed countries. Learn about the environmental challenges and risks associated with these newly emerging national economies.

What Is Industrial Ecology? - Definition and Examples

10. What Is Industrial Ecology? - Definition and Examples

Industrial ecology is a young science that studies industrial systems with the goal of finding ways to lessen their environmental impact. Learn how industries are using industrial ecology to reduce the use of natural resources and generate less waste.

Pollution: Physical, Chemical & Biological

11. Pollution: Physical, Chemical & Biological

Pollution is the presence of unwanted substances in an environment. It is often the result of human interference. Learn about physical, chemical and biological pollutants and see examples of each.

Human Causes of Eutrophication

12. Human Causes of Eutrophication

Eutrophication occurs when a body of water becomes overly enriched with nutrients. While this can happen naturally, accelerated eutrophication is typically the result of human activities. Learn about the human causes of eutrophication.
