1. Biotic Potential and Carrying Capacity of a Population
When you look around, you can see a number of different individuals and species. In this lesson, we will explore the factors that control and define how many organisms can really inhabit a particular ecosystem or habitat.
2. Population Size: Impacts on Resource Consumption
What are the things you need to survive? Humans all need resources, and in this lesson, we will discuss how the growth of the human population is influencing the natural resources we rely on.
3. Thomas Malthus' Theory of Human Population Growth
In this lesson, we will explore the ideas of Thomas Malthus and his predictions for the growth of the human population. We will also investigate if his predictions have come true or not.
4. Use of Pesticides: Benefits and Problems Associated with Pesticides
Pesticides are used worldwide to manage agricultural pests. They kill and repel unwanted pests, but also cause many human deaths each year. This lesson explores the widespread use of pesticides in agriculture and compares the benefits and problems associated with these helpful but dangerous chemicals.
5. Bioremediation: Microbes Cleaning Up the Environment
Bioremediation uses living organisms to clean up pollution. In this lesson, we will examine the role of microbes in bioremediation and why it is not a perfect solution for degrading environmental pollutants.
6. Deforestation: Definition, Causes & Consequences
Deforestation is the clearing of trees without the intent of replacing them or reestablishing a stand of trees. Learn reasons for deforestation and discover the consequences of this process in all forests, including tropical forests.
7. Land Conservation: Preserving and Restoring Ecosystems
Humans have degraded a large portion of natural land. The field of land conservation has become popular as a way to fix this problem. Land conservation attempts to combat land degradation through preservation, restoration, remediation, and mitigation.
8. The Nitrogen Cycle, Acid Rain and Fossil Fuels
Do you know the difference between nitrite and nitrate? Do you have any clue how all the nitrogen in the atmosphere becomes usable? If you can't answer these questions, then you need to watch this lesson on the nitrogen cycle.
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. 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.
11. Water Conservation: How Water Management Can Lead to Sustainable Use
In this video lesson you will learn about the importance of water conservation. You will also learn about the two ways freshwater is used, and how proper water use can lead to sustainability in agriculture, homes, and manufacturing.
