Causes of greenhouse effect(2)FarmingAnimals, particularly cattle and sheep, produce methane as food breaks down inside them. Some fertilisers release nitrous oxide. Rice production in paddy fields generates methane under water.
Waste breakdownWhen organic material such as food scraps, garden wastes and paper are dumped in landfills, their decay creates carbon dioxide and methane. Sewage and wastewater treatment plants also release these gases as they break down wastes.
IndustryMany industrial processes create greenhouse gases. For example, cement and aluminium production involves chemical reactions that produce a variety of greenhouse gases.
Emission of gasesAnother man-made causes of the increase in the Green house effect due to the emission of such gases are any all electrical appliances. Even the humble refrigerator in the house emits gases which contribute to the Greenhouse effect. These gases are known as Chloroflourocarbons (CFCs) and are used in refrigerators, aerosol cans, some foaming agents in the packaging industry, fire extinguisher chemicals and cleaners used in the electronic industry. Some processes of the cement manufacturing industries also act as a cause towards the Greenhouse effect.
Population GrowthPopulation growth also is a indirect contributer and one of the causes of the Greenhouse effect. With the increase in population, the needs and wants of the people increase. Therefore, this increases the manufacturing processes as well as the industry processes. This results in the increase of the release of industrial gases which catalyse the green house effect. The increase in population also results in the increase of agricultural processes. Most man-made machines, like the automobile also contribute to the green house effect.
