Our world is the beginning and the end. Before humankind our Earth was healthy and its inhabitants did not have to worry about the ozone layer or Earth's temperature increasing. Now, along with our many everyday stresses, we have worries about our world heating up; also known as global warming.

The sun and the cycle of the "greenhouse effect" is what keeps all of humankind living. The sun aides the weather, climate, and surface temperature of the Earth. Once our Earth receives this energy it radiates it back into space. The "greenhouse effect" is what helps to make our Earth's temperature comfortable and not too low, basically, it is what keeps our world alive and functioning (Global Warming, 2003). In order to keep this effect balanced and intact we must do whatever we can to prevent it from getting too low or too high so that we are able to live in this world for more years to come.

First, what is global warming? Global warming is when our natural "greenhouse effect" increases; many scientists believe that this is particularly due to human activities. Since the days of the industrial revolution, we have had increases in many chemicals, like carbon dioxide, methane, nitrous oxide, etc. in our atmosphere thus increasing the Earth's heat trapping capability. With increasing temperature, snow from both poles, northern and southern, will surely melt and eventually water levels will rise and Earth will be under the ocean. "Plant respiration and the decomposition of organic matter release more than 10 times the CO2 released by human activities; but these releases have generally been in balance during the centuries leading up to the industrial revolution with carbon dioxide absorbed by terrestrial vegetation and the oceans" (Global Warming, 2003). It is difficult to change the...
