Global thaw - Speech or Presentation ExamplePollution refers to any foreign material that is discharged into water, nervous strain or land. These materials either have acute or chronic effects on the environment. The pollutants discharged into air leash to global warming. Some of the pollutants include blow IV oxide, methane, nitrous oxide, fluorinated gases among others (Faust, 2008, p51).The greenhouse effect is the leading factor that leads to global warming. The Greenhouse effect, as it is commonly known, refers to the consequences of the emission of greenhouse gases into the atmosphere (Faust, 2008, p79). Greenhouse gases suckle infr ared radiation from sunlight and in the process trap heat in the atmosphere. The production of greenhouse has increased in the recent past and this due to the pace of modernization. Fossil fuels are still being used in factories and vehicles, in spite being in the 21st century fossil fuels. The blaze of fossil fuels increases the percentage of CO2 in the atmosphere (Faust, 2008, p83). The increase in the percentage of Carbon (IV) Oxide leads to increased global warming.The sun emits ultraviolet radiation and the ozone storey shields us from this radiation. The layer is made up of Ozone (O3), which is very rare compared to other gases in the atmosphere (Faust, 2008, p21). Studies have found that increase global warming reduces the ascendency of the ozone layer of absorbing UV radiation. Global warming slowly increases the temperature of the Earths surface thereby leading to a cold stratosphere. Reduced temperatures lead to the slower repairing of the layer exposing humans to dangerous UV radiation. This radiation causes cancer in both humans and animals (Faust, 2008, p34).Global warming has adverse effects that are hard to ignore. Furthermore, scientists forecast a bleak future for the human race if global warming is not reduced. Reducing the emission of greenhouse gases reduces global warming (Faust, 2008, p84). The
