About This Chapter
Praxis Biology: Human Impacts on the Environment - Chapter Summary
In this chapter, the instructor will discuss the relationship between human beings and the environment, with a focus on the same subject matter found on the Praxis Biology test. To help you answer the exam questions correctly, the lessons include the following topics:
- Fossil fuels, including their advantages and disadvantages, greenhouse gases and global warming
- Definition and differences between renewable and non-renewable resources
- Chemical, biological and physical pollutants, including air and water pollution
- Declining biological diversity, deforestation and desertification
- Conservation biology and ecological restoration
- How mineral are extracted and processed, including environmental impacts
- Definitions, benefits and issues associated with the green revolution, sustainable agriculture and sustainable forest management
These topics are discussed in an easy-to-follow video presentation, where the instructor uses examples and illustrations to help you understand the information. At the end of the lesson, you'll also find a summary that can further help you prepare for the Praxis Biology Exam.
Objectives of the Praxis Biology Test: Human Impacts on the Environment Course
The Praxis Biology test is designed to assess how prepared potential teachers are to teach biology at the secondary school level. Available in both computer-based and paper form, it consists of 150 multiple-choice questions, with approximately 7% of the questions related to the issue of science, technology and society. Developed in conjunction with content specialists, educators and high school biology teachers, the test reflects both the National Science Education Standards and those set by the National Science Teacher Association.
Every lesson in the Human Impacts chapter is accompanied by an online quiz, which provides you with an easy way to see how well you absorbed the major points of the tutorial. In terms of content and presentation, these questions are very similar to the ones found on the actual exam.
1. What Are Fossil Fuels? - Definition, Advantages & Disadvantages
Fossil fuels are sources of energy that developed within the Earth over millions of years. The three main types of fossil fuels are coal, oil, and natural gas. Explore the definition of fossil fuels, and learn about their creation, how they are used as energy, and their advantages and disadvantages.
2. Fossil Fuels, Greenhouse Gases, and Global Warming
Fossil fuels and greenhouse gases are some of the environmental factors that contribute to global warming. Learn about these factors and how humans affect the carbon cycle, and perhaps understand that global warming isn't the end of the world as yet.
3. Renewable & Non-Renewable Resources: Definition & Differences
Resources which are naturally replenished by the environment are known as renewable resources, whereas those which replenish too slowly for use, or not at all, are considered non-renewable. Explore the implications and differences of these two types of natural resources.
4. Pollution: Physical, Chemical & Biological
Pollution is the existence of unwanted and harmful substances in the environment. Learn more about different types of pollution (including physical, chemical, and biological) and how they can negatively affect the environment.
5. What Is Air Pollution? - Definition, Sources & Types
Air pollution is a mixture of harmful particles and gases in the atmosphere. Learn the definition of air pollution, discover its sources, and explore the different types of air pollutants that exist.
6. Water Pollution: Definition, Types, and Sources
Water is arguably our most precious resource; however, water pollution can have detrimental effects on the health and welfare of people throughout the world. Learn what water pollution is and its sources, and distinguish between surface and groundwater pollution.
7. Deforestation: Definition, Causes & Consequences
The mass clearing of trees with no intention of replacing the trees is called deforestation. Learn more about the definition, causes, and global consequences of deforestation and its cousin, clearcutting.
8. Deforestation, Desertification & Declining Biological Diversity
Natural environments such as forests must be managed to ensure they stay healthy and are supporting their part of the ecosystem. Explore deforestation and desertification and learn how these affect declining biological diversity, understand the importance of declining biological diversity, review specific impacts of deforestation, and recognize the factors that cause desertification.
9. Ecology Restoration: Foundations, Projects and Goals
Restoration ecology repairs the ecosystems damaged by human action, habitation, and interruption. Learn the background and definition of restoration ecology, then explore its foundations, projects, and goals.
10. Extraction and Processing of Minerals & the Environmental Impacts of Mineral Use
There are a variety of ways that minerals can be mined from the Earth, including surface mining, strip mining, and subsurface mining. Learn more about how mineral are extracted and what harmful environmental effects can occur from such processes.
11. Environmental Sustainability: Definition and Application
In order to sustain the beauty and natural function of the environment, humankind must first take drastic steps toward environmental sustainability and avoid actions that harm or deplete it. This lesson will discuss environmental sustainability, its application, and its many subsections including sustainable agriculture, forestry, and energy.
12. Sustainable Development within Environmental Limits
Sustainable Development describes advancements or projects that can be enacted without significantly impeding environmental health. Explore the influence of natural replenishment on this principle, and the environmental limits considered in protecting future generations' resources.
13. What Is the Green Revolution? - Definition, Benefits, and Issues
The Green Revolution is the period when agricultural productivity skyrocketed due to new technologies being introduced. Learn the definition of different concepts related to the Green Revolution and the benefits and issues brought by the revolution.
14. What Is Sustainable Agriculture? - Definition, Benefits and Issues
Sustainable agricultural practices produce crops and livestock while protecting the environment. Learn the definition of sustainable agriculture, then explore its benefits and issues.
15. What Is Sustainable Forest Management? - Definition and Examples
Sustainable forest management is the practice of preserving a forest's health while regulating forest resources to meet the needs of society and industry. This lesson provides an overview and examples of sustainable forest management and discusses the Forest Principles and benefits of practicing sustainable forestry.
