About This Chapter
MTLE Earth & Space Science: Humans & the Environment - Chapter Summary
Use the detailed lessons presented in this study guide chapter to explore the very impactful relationship humans have with the environment. These lessons outline how humans have directly and indirectly affected the environment. You'll look at topics including:
- Progression of deforestation to desertification to declining biodiversity
- Results of the Agricultural and Industrial Revolutions on the environment
- Rise of industrial development across the globe and studying that impact through industrial ecology
- Types of pollutants and the causes and sources of air and water pollution and Eutrophication
- Systems used to determine factors of human impact, including IPAT
After examining these topics in detail through the video lessons, you will have a refreshed knowledge of these concepts and be adequately prepared for this portion of the MTLE Earth & Space Science exam. Apply your comprehension of these concepts to the lesson quizzes and chapter exam in this unit to assess if further review is needed. Access specific topics within the lessons by clicking on the direct links within the quizzes. Full video transcripts with highlight key words and useful quiz worksheets are also available as study resources. Instructors are also always available to answer questions should they arise.
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. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. 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.
10. 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.
11. 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.
