Learn how the atmospheric temperature can increase leading to global warming, explore some of its causes and how it affects climate change, and discover the role of the greenhouse effect on global warming.
4. The Ozone Layer: Importance and the Harmful Effects of Thinning
The ozone layer of the Earth absorbs the ultraviolet radiation coming from the Sun. Learn about the importance of ozone, discover how CFCs break down the ozone, explore the early discoveries about harmful effects of CFCs and the thinning of the ozone layer, and determine policies in place to protect the ozone.
5. 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.
6. Environmental Problems Associated With Groundwater
Groundwater is our largest natural source of freshwater, but several environmental problems threaten the underground aquifers that contain it. Explore how groundwater is vulnerable to issues like pollution, overdrawing, and subsidence, and discover how these problems impact the planet's water supply.
7. Water Treatment: Improving Water Quality
Water treatment is the process of removing harmful substances from water to make it suitable for use. Explore how water quality is improved, the process of water purification, how wastewater is treated, and the quality of drinking water in developing countries.
8. The Clean Water Act & Safe Drinking Water Act: Legislation for Clean Water
In the early 1970s, the US Environmental Protection Agency (EPA) passed the Clean Water Act and Safe Drinking Water Act to regulate water pollution and increase the standards for safe drinking water.
