Global Warming Causes Essay
Global warming is the increase in the earth’s average temperature due to release of several greenhouse gases to the atmosphere by humans. Global warming is affecting many parts of the world. Due to global warming, the glaciers are melting which is causing the rise in the sea level. When the level of the sea rises, it causes danger to the people living in the low lying areas.
When the level of the sea rises, it covers the plants and causes some of them to die. When they die, animals lose their main source of food. We, human beings lose our two sources of food, plants and animals. It may also force people to lose their homes. In other words, the whole chain will get affected if nothing is done on time to stop global warming …show more content…
Forest Fires: Deforestation by nature is another leading cause of global warming. Natural forest fires are usually televised on the news, showing the devastation of mountain homes and communities. While this loss is tragic, the effects of these natural occurring forest fires pose a problem for the earth’s air. Forest fires emit carbon-filled smoke into the atmosphere, and new forests’ growth is slow and not stable enough to produce the much needed oxygen into the newly, suffocating carbon air. Natural forest fires will eventually run their course, but left in the ashes are polluting gases that get trapped in the …show more content…
Deforestation is blamed for rise in the greenhouse gases present in the atmosphere by cutting or burning them. New development projects, requirement of land for homes and factories, requirement for wood and also soil erosion are the major factors that are causing deforestation, which in turn leading to global warming.
2. Fossil Fuels: Pollution whether it is vehicular, electrical or industrial is the main contributor to the global warming. Everyday billions of vehicles release various gases into the atmosphere. This causes earth to warm up and increase its average temperature. Electricity causes pollution in many ways. Over 75% of the electricity worldwide is produced by burning of fossil fuels. Many gases are sent into the air when fossil fuels are burnt of which main is the carbon dioxide gas.
Fossil fuel like coal is burnt to produce electricity. Coal is the major fuel that is burnt to produce power. Coal produces around 1.7 times as much carbon dioxide per unit of energy when flamed as does natural gas and 1.25 times as much as
