Study Notes
Non-Renewable Resources
- Fossil fuels are an example of a non-renewable resource.
Importance of the Ozone Layer
- The main function of the ozone layer in the atmosphere is to protect the Earth from harmful ultraviolet (UV) radiation.
Deforestation
- The human activity that contributes most to deforestation is agriculture, mainly for livestock and crops.
Ocean Acidification
- The primary factor contributing to the acidification of oceans is the absorption of excess carbon dioxide (CO2) from the atmosphere, mainly due to human activities such as burning fossil fuels.
Ozone Layer Depletion
- The major cause of the depletion of the ozone layer in the atmosphere is the release of chlorofluorocarbons (CFCs) and other halogenated gases, mainly from human activities such as the production and use of aerosol cans and refrigerators.
Eutrophication
- The activity that significantly contributes to eutrophication of water bodies is the release of excess nutrients, mainly from human activities such as agricultural runoff, sewage, and industrial waste.
- The primary cause of eutrophication in water bodies is the excess of nutrients, particularly nitrogen and phosphorus, which triggers the overgrowth of algae and depletes the oxygen in the water.
- Human activities, mainly the release of nitrogen and phosphorus, have the most significant impact on the depletion of the ozone layer.
