Thebiggest threat to the survival of the planet is pollution of theenvironment. There are various ways through which people pollute theenvironment, but the biggest one of them all is the release ofgreenhouse gases into the atmosphere. These are carbon-dioxidemethane, water vapor, nitrous oxide, chlorofluorocarbons, ozone (Linet al., n.d., 2013).When these gases are released into the atmosphere, they cause thegreenhouse effect, which is a natural process where the earth’ssurface becomes warm. Warming takes place when the energy from thesun is absorbed and re-radiated instead in the Earth’s atmospherebecause of the greenhouse gases. Once the energy has been absorbed,the surface and the atmosphere of the earth gets warm (Linet al., n.d., 2013).

Warmingof the Earth’s atmosphere should be only be maintained at 33degrees Celsius in order to allow life to exist on Earth (Linet al., n.d., 2013).The problem, however comes in when greenhouse gases are increased inthe atmosphere through land clearing and burning of fossil fuels suchas oil, coal and natural gas. This causes more heat to be trapped bythe increased concentration of gases than it should actually be andthe end result is increased temperatures on Earth.

Globalwarming has various devastating environmental impacts apart fromincreased temperatures such as decreased snow, glacier coverage andsea ice. This will in turn lead to rising sea levels as well as theincrease in coastal flooding. The Arctic also gets affected throughthawing of the permafrost because of the high temperatures (Shugart&amp Woodward, 2011).

Thefrequency and severity of waves and storms is also likely t increasedue to global warming. In addition, wild species, both on land and inthe sea are likely to be affected by new diseases and invasivespecies (Shugart&amp Woodward, 2011).These three are some impacts that are likely to affect us if we donot reduce pollution.
