What are the effects of Global Warming on Civilization?


What are the effects of Global Warming? How are we as in humans contributing to Global warming and the increase in greenhouse gases? Well there are many factors that lead to Global Warming but the main factor is humans. Everyday civilization creates what we know as fossil fuels. Fossil Fuels are the burning of coal and petrol. These fossil fuels make up the greenhouse gases. Also by cutting down the rainforest or other types of forest we are cutting out the supply of oxygen and increasing Carbon Dioxide which is not good. Also every time an animal dies they release methane gases from their corpse. Every time a person uses a car or a hairspray this person is releasing CO2 by using a car or when he uses a hairspray some of these sprays contain CFCs (chlorofluorocarbons) which widens the hole the ozone layer has. The Ozone layer is part of the earth’s atmosphere protects humans from harmful UVB Rays. When there are two many UVB rays inside the earth, the earth will be super-heated and this is what we call Global Warming.
