About This Chapter
Humans and the Environment - Chapter Summary
This chapter will provide you with fun and short video lessons about the effect of fossil fuels and greenhouse gases on Earth, physical and chemical pollution, habitat destruction and other human factors that endanger the planet, and other subjects! When you've completed the lessons, you can take short quizzes that test how well you've understood them. Additional subjects in this chapter include the following:
- Deforestation and decreasing biological diversity
- Over-exploitation of humans
- Effects of humans on the environment
- Foundations and goals of ecology restoration
Use the video tags to travel to different subjects in the videos. This chapter is mobile-friendly and allows you to take it wherever you go. Take a peek at the lesson transcripts for highlighted keywords. Any questions you have can be sent straight to the instructors.
1. 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.
2. 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.
3. Pollution and Habitat Destruction: The Human Factors Contributing To Endangerment & Extinction
In this lesson you will learn about two ways humans contribute to species extinction. We break up habitats by building roads and clearing land, and we pollute both land and water. You will also learn about the specific terms used to describe the processes, habitat fragmentation and anthropogenic pollution.
4. 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.
5. Over-Exploitation: How Humans Affect Ecosystems By Decreasing Species Populations
In this lesson, you'll learn how humans overexploit or overharvest species. You will discover the primary way in which humans are responsible for overfishing. You will also learn about how this negatively impacts ecosystems.
6. 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.
7. Ecology Restoration: Foundations, Projects and Goals
In this lesson you will learn how humans have damaged various ecosystems on the planet and how a branch of ecology, restoration ecology, aims to restore these ecosystems. You will discover the main goal of restoration ecology as well as some of the ways habitats are restored.
