Causes of greenhouse effect

Greenhouse Gas Effect
The greenhouse effect is a natural process, without it, earth’s temperature would be below -18 Celsius. It enable to hold enough heat within the atmosphere to support every kind of life on the planet and maintainsthe Earth’s temperature at around 33 degrees Celsius warmer than it would otherwise be.
Greenhouse gases include carbon dioxide, methane, nitrous oxide, ozone, water vapor and some artificial chemicals such as chlorofluorocarbons (CFCs), perfluorocarbon (PFC).

• Carbon dioxide, 9–26%produced by burning solid waste, wood and wood products, and fossil fuels such as oil, natural gas, and coal
• Water vapor, 36–70%
• Methane, 4–9% emitted by livestock or by the decomposition of organic wastes in municipal solid waste landfills
• CFC manufactured by the industry for use in coolants and insulation
• Ozone, 3–7%pollutants emitted by power plants, industrial boilers, vehicles and refineries

However, the real issue arises when greenhouse gas levels get rapidly increase because of human activities, trapping too much of the sun’s heat and damage the natural systems that regulate our climate.
When the Sun’s energy hits the Earth’s atmosphere, some of it is reflected back  and the rest is absorbed and re-radiated by the greenhouse gases. With more greenhouse gases, heat will stick around, and it will trap the sun’s warmth in the planet’s lower atmosphere causing global warming.

Causes of greenhouse gas effects
1. Burning of fossil fuel
Carbon stored inside fossil fuels such as oil, natural gas, and coal is released which combines with oxygen in the air to create carbon dioxide. With the increase in the number of vehicles and population greenhouse effect will be getting higher and higher
2. Deforestation
Burning or clearing trees reverses the effects of carbon sequestration and releases mainly carbon dioxide and other greenhouse gases into the atmosphere. Lands converted from forests to paddy produce methane gas which also contributes to the greenhouse effect
3. Increase in population
Due to rapidly increased demand for food, cloth and shelter releasing of greenhouse gases to the atmosphere will be increased too. Also, the extensive usage of fossil fuels will also be a problem
4. Farming
Emitted by livestock or by the decomposition of organic wastes in municipal solid waste landfills. The usage of fertilizer will increase the emission of nitrous oxide to the atmosphere and contributes to the greenhouse effect which in turn leads to global warming.

5. Industrial wastes and landfilling
In the waste sector, typically, CH4 emissions from solid waste disposal are the largest source of greenhouse gas emissions.  . CH4 emissions from wastewater treatment, incineration and open burning of waste containing fossil carbon, e.g., plastics, are also the most significant sources of CO2 emissions.
