About This Chapter
Human Activity and the Biosphere - Chapter Summary
Look over information on how the periods of the Agricultural Revolution and the Industrial Revolution affected the environment. You'll see an analysis of environmental concerns stemming from industrial development occurring in emerging nations. The remainder of the chapter's content includes:
- A breakdown of the IPAT equation
- Global climate change effects and mitigation strategies
- Deforestation, desertification and lessening biological diversity
- Fossil fuels and greenhouse gases
- Global warming
- Biological, chemical and physical pollution types
Once you've watched a video lesson on one of these content areas, you can quickly get back to any segment you want to review by using the jump feature in the timeline. The key terms in each lesson appear in bold print in the corresponding transcripts for easy reference. You can take a multiple-choice practice quiz with each lesson for an accurate self-assessment.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
