Effects of Humans on the Environment - Chapter Summary
Our video lessons, transcripts, quizzes and other study tools can help you learn more about how humans affect the environment. For instance, they can be used to find out about ways in which deforestation and desertification can be harmful to the environment. You can also discover some of the implications of physical and chemical pollution. These lessons will help you to:
- Recall what IPAT is
- Discuss what deforestation and desertification are
- Learn how agriculture affects the environment
- Describe the effects of the Industrial Revolution and the Agricultural Revolution on the environment
- Give examples of industrial ecology
- Identify the different types of pollution
- Determine the human causes of eutrophication
Experts in the field of environmental science created these lessons with you in mind. You can view the videos or access the text transcripts to study this topic. We also offer self-assessment quizzes you can use to measure your understanding and make sure you are retaining the information before moving forward to other lessons or chapters.
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
