Who's it for?
This chapter of our high school biology tutoring solution will benefit any student who is trying to learn about human effects on the environment and earn better grades. This resource can help students including those who:
- Struggle with understanding the nitrogen cycle, greenhouse gases, pollution, deforestation or any other human effects on the environment topic.
- Have limited time for studying
- Want a cost effective way to supplement their science learning
- Prefer learning science visually
- Find themselves failing or close to failing their human effects on the environment unit
- Cope with ADD or ADHD
- Want to get ahead in high school biology
- Don't have access to their science teacher outside of class
Why it works:
- Engaging Tutors: We make learning about human effects on the environment simple and fun.
- Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
- Consistent High Quality: Unlike a live biology tutor, these video lessons are thoroughly reviewed.
- Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about human effects on the environment on the go!
- Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.
- Explain how the burning of fossil fuels affects the nitrogen cycle.
- Describe how the carbon cycle leads to long-term carbon storage.
- Learn how fossil fuels and greenhouse gases contribute to global warming.
- Discuss different types of pollution, including physical, biological and chemical.
- List sources and types of water pollution.
- Identify sources and types of air pollution.
- Describe the function of the ozone layer and explain how the thinning of the ozone layer is harmful.
- Explain how habitat destruction and pollution caused by humans leads to endangerment and extinction.
- Learn how deforestation and desertification are harmful to biological diversity.
- Discuss how over-exploitation of certain species affects ecosystems.
1. 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.
2. The Carbon Cycle and Long-Term Carbon Storage
All living organisms have a role in the carbon cycle. Do you know you understand how humans, animals and plants use carbon? This lesson will introduce you to the carbon cycle and explain how it functions on a global scale.
3. 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.
4. 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.
5. 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.
6. 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.
7. The Ozone Layer: Importance and the Harmful Effects of Thinning
In this lesson, you will learn the importance of the ozone layer and how it is depleted. You will also study the research and policy that has been instrumental in its recovery.
8. 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.
9. 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.
10. 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.
