Axia College, University of Phoenix [COM 220- 08 March 2009] Have you ever watched a television program, or read an article about Global warming? A person would be hard pressed to find someone who hasn’t. The news is hard to ignore since the information that is given to us comes from scientists or experts in the field of global warming. We are continually bombarded with information that the Earth is experiencing a warming trend, and human activity is to blame. The pollution that man creates is adding to the earth’s greenhouse gases. The resulting affect of global warming is triggering warmer temperatures around the world, and ecosystems are taking the toll. One of the most publicized looming catastrophes is the plight of the polar bears. Once the glaciers are gone, the polar bear will be extinct in the wild. Although, scientists say it is caused by the pollution that humans are creating, global warming is a natural phenomenon. Snow capped mountains are a wondrous sight to behold, and can be found on every continent. But, these massive ice shelf’s have a purpose that many people take for granted. Many people do not realize that glaciers are responsible for part of the world’s water supply. Revkin (2003) states “The melting is likely to threaten water supplies in places like Peru and Nepal” (¶ 19). The result from the melting glaciers will raise water levels and potentially create devastating floods over time. The eventual outcome that these countries will face once the glaciers are gone is drought. Many communities are also dependent on hydroelectric dams and water reservoirs to create electricity. Once the glaciers are gone then what? Scientists think that without water from the glaciers to create electricity, these communities that are so dependent on the hydroelectric dams will need to use coal or oil to create the necessary
