1. Increasing Emissions of Greenhouse Gases: Human activities are the main causes of the increasing emissions of greenhouse gases, such as carbon dioxide, methane and nitrous oxide. These gases trap heat in the atmosphere, leading to an increase in global temperatures.
2. Deforestation: Cutting down trees, especially in tropical forests, has led to an increase in the amount of carbon dioxide in the atmosphere. Trees absorb carbon dioxide, and without them, the gas accumulates in the atmosphere, trapping heat and leading to global warming.
3. Agriculture: Intensive farming and the large-scale use of fertilizers release large amounts of nitrous oxide, a powerful greenhouse gas, into the atmosphere.
4. Industrial Activities: Burning fossil fuels such as coal, oil and natural gas for energy production, releases carbon dioxide and other harmful gases into the atmosphere.
5. Mining: Mining activities, especially coal mining, release large amounts of carbon dioxide into the atmosphere.
6. Burning of Waste: Incineration of waste releases large amounts of carbon dioxide and other hazardous gases into the atmosphere.
7. Urbanization: Urbanization increases the amount of heat-trapping gases in the atmosphere, leading to a rise in temperatures.
8. Ozone Depletion: Ozone depletion leads to an increase in ultraviolet radiation reaching the earth’s surface, leading to a rise in global temperatures.
9. Natural Disasters: Natural disasters such as volcanic eruptions and forest fires release large amounts of carbon dioxide and other gases into the atmosphere, leading to global warming.
10. Ocean Acidification: Increasing levels of carbon dioxide in the atmosphere leads to ocean acidification, which can lead to a rise in global temperatures.
