Abstract:

Green-house effects: A material perspective

A- Which materials and how do those materials cause air pollution?

(Carbon dioxide and monoxide emissions causes…)

B- How could air pollution affect us?

C- Which materials and how do those materials cause green-house effects?

D- How does green-house effect work?

E- What is the importance of green-house effects?

F- What could be done as solution for prevention?

Actually green-house effects can be divided in two terms: “First is a natural effect” which maintains Earth warm and habitable and the “Second is an artificial or man-made effect” which enhance natural green-house effects adding gases such as: sulphur dioxide Carbon monoxide; Carbon dioxide; Ozone; Chlorofluorocarbons released

Ozone protects humans from sun’s ultraviolet radiation in the stratosphere. But at ground stage ozone is a toxic pollutant causing multiple health issues. Ozone is a key element of smog. Elsewhere, any human’s actions that involve combustion, chemical substance or releasing toxic gas are causes of air pollution. In past, all air pollution was generated by the Industrial revolution. But now with all laws and awareness campaigns against air pollution, what come in the mind is: where is this air pollution still from? As answer to this question, scientists involved facts such as traffic, power plants and factories as the potential causes of the (artificial) air pollution (8). Now let’s survey answers closely.

• Today the amount of cars is estimated to half a billion, which makes traffic much heavier than it was in past decades. All those cars (engines) required gasoline or others kind of carburant. As known, fuels like petroleum used to power cars is made up of hydrocarbons; and burning fuels combustion produce carbon dioxide. As result of this fuel use, exhausts from engine all kind of pollutants such as carbon monoxide, nitrogen oxide, volatiles organic leading to

“Land changes use is also source of green-house gas emission such as deforestation resulting carbon dioxide (on trees or soils)” (11)

• Forests help maintain the nature balanced absorbing the excess carbon dioxide in the air meaning that deforestation increase carbon dioxide levels and enhance green-house effect.

• Green-house effect can be released from burning fossil fuels such as oil, coal, materials used in industries (i.e. Cement manufacturing) and gases in the atmosphere.

• Another example of man-made causes of green-house effect is its gases emissions electrical industries such as chlorofluorocarbons (in electronic industry).

• Population growth (needs, goods, wants) require deforestation, manufacturing or industry process (which spew industrial gas and catalyse green-house effect) is an indirect contributor too (12).

Scientist say gases may contribute to green-house effect too and the most important gas in man-made components of green-house effect is the carbon dioxide. But among gases we
