The Environmental Reasons
Greenhouse Gases
The earth's atmosphere is made up of mainly oxygen and nitrigen, with smaller amounts of other gases either naturally occuring or man-made. However neither oxygen or nitrogen play any significant part in the greenhouse effect. This greenhouse effect is caused by the presance of water vapour, carbon dioxide and other gases which are emitted in smaller quanities. These absorb the natural energy radiation that leaves the earth's land and transfers between it, space and oceans. Changes in the quanities of the gases can and do alter the balance of these energy transfers. However some of the greenhouse gases are naturally occuring, these are water vapour, carbon dioxide, methane, nitrous oxide and ozone. There are, however some that are mainly man-made, these being those sustances that contain flourine, cholrine or bromine.
The greenhouse gas that this project is interested in is carbon dioxide.
