The Main Causes of Global Warming - Essay Example Greenhouse gases are increasing in percentage in the atmosphere. A release of methane gas from the wetlands and the arctic tundra is a cause of global warming (. Methane gas traps heat in the atmosphere of the earth. Methane is also released from agriculture and landfills, as well as from the grazing animals’ digestive systems. Fertilizers release nitrous oxide which is also a greenhouse gas. Carbon dioxide is another gas that is responsible for global warming and its percentage in the atmosphere is rapidly increasing as a result of deforestation. These are very powerful gases as causes of global warming. â€Å"A molecule of methane produces more than 20 times the warming of a molecule of CO2. Nitrous oxide is 300 times more powerful than CO2† (â€Å"Causes of Global†). Lack of sufficient or efficient recycling is another cause of global warming. Since more material gets wasted than is recycled, the deficiency thus produced is addressed by extracting new minerals, metals, and materials from the earth through operations and processes, that not only result in a depletion of the natural resources in the earth, but also generate tremendous amounts of greenhouse gases into the atmosphere (â€Å"Recycling†). Lack of sufficient recycling is thus an indirect cause of global warming. If proper channels and laws are established to thrive in the practice of recycling, there can be brought a considerable reduction in demand as well as global warming. Another cause of global warming is the carbon released into the atmosphere as a result of the burning of fuel. Ever since man-made vehicles and started driving them with the combustion of fuel, carbons have been released into the atmosphere.
