Global warming

Global Warming is a big problem in today's society. Global Warming, also known as the Greenhouse effect, is a problem everyone will soon have to face.  In my opinion. the impacts of human influences have grown? so have the risks associated with those impacts. New technologies carry increasing risks? and the scale? frequency? and impacts of disaster caused or influenced by human activity are growing tremendously. The risks to the Earth's natural systems are becoming significantly concerning. (John 2000)

It is observed that carbon Dioxide comprises only a small portion of the atmosphere. It is colorless? odorless gas yet vitally important to life on earth. Actually too much Carbon Dioxide can be just as dangerous as too little. The greater amount of carbon dioxide? the greater amount of heat absorbed. The heat absorbed remains in the atmosphere rather than being radiated back into space. There are many signs that the levels of Carbon Dioxide in our atmosphere is increasing. This threatens the balance between the amount of solar energy reaching the earth.

I believe that breathing for humans consists of taking in oxygen and getting rid of waste gases such as Carbon Dioxide. Carbon Dioxide is a byproduct of many industrial processes? including the fermentation of sugars to produce alcohol? the decomposition of limestone to make quicklime and the manufacture of cement. But the main sources are the burning of fossil fuels and the destruction of forests. (Melvin 2002)

Because plants themselves need Carbon Dioxide Through photosynthesis plants absorb Carbon Dioxide and act as a natural defense against global warming. This deforestation increases Carbon Dioxide in the atmosphere in two ways. One with out the forests? Carbon Dioxide that would have been absorbed for photosynthesis remains in the air. The other is when the forest is burned or if trees ...
