We have engaging video lessons that come equipped with convenient video tags, making it easy to jump from one concept to the next. Each of our lessons include in self-assessment quizzes, making it easy to assess your knowledge. Most importantly, however, our lessons are taught by expert instructors making our curriculum especially reliable.
1. 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.
2. 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.
3. 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.
4. Water Resource Issues: Activities Affecting the Water Supply
This video lesson describes water resources issues such as aquifer depletion, overdrawing surface waters and salinization of irrigated soil. You will also learn about the impacts of activities affecting water resources.
5. 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.
6. Environmental Problems Associated With Groundwater
Groundwater is an important natural resource, but like many of our other resources, it's affected by the surrounding environment and human activities. In this video lesson, you'll learn about some of the environmental problems associated with groundwater and why groundwater is especially vulnerable to them.
7. 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.
8. 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.
9. Controlling Air Pollution: How Developed & Developing Nations Differ
In this lesson, you will learn how air pollution is controlled in developed and developing nations. You will also learn about the U.S. Clean Air Act and how it has evolved over the years to address air pollution in the United States.
10. Acid Deposition: Definition, Causes & Effects
In this video lesson, you will learn what causes acid deposition and how it forms in the atmosphere. You will also see some examples of the damage that acid deposition can cause to natural ecosystems and man-made structures.
11. Greenhouse Gases and the Enhanced Greenhouse Effect
In this video lesson, you will learn about the five main greenhouse gases and how their unnaturally high concentrations are leading to the enhanced greenhouse effect and global climate change on Earth.
12. Global Warming: Atmospheric Causes and Effect on Climate
Global warming is a multifaceted, complex issue. It involves both natural and human causes that can increase the amount of greenhouse gases. This lesson looks at some of the facts about global warming and how they could contribute to climate change.
13. Extraction and Processing of Minerals & the Environmental Impacts of Mineral Use
In this lesson, you will learn about the different methods used to extract minerals from the ground and gain an understanding about how different types of mining affect the environment.
14. Global Mineral Reserves: Sustainability, Economic Implications, and Environmental Effects
Minerals are vital components of our everyday lives, but each mineral only exists in a finite amount on Earth. How do we find a balance between supporting economies while also protecting the environment and ensuring the use of minerals for future generations?
