“Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions” (EPA). Our world has gone through several stages in its lifetime. It takes time to deal and cope with changes, just like anything else. Over the years, the earth has been gradually getting warmer due to pollution. Humans, however, were slow to take the necessary actions to prevent it from getting any worse. Due to the ignorance of people we are on the edge of a very dramatic change, Global Warming. If we continue to go on with our lives, ignorant to the consequences of our actions, we will face drastic and devastating loss.
Human activities add to the levels of these gasses, causing more problems. “Automobiles, heat from homes and businesses, and factories are responsible for about 80% of today's carbon dioxide emissions, 25% of methane emissions, and 20% of the nitrous oxide emissions" (Thinkquest). In the future, it will be hard to produce food. When Global warming really starts causing detrimental problems, we will have droughts and floods rather often, not allowing crops to grow. Another issue is acid rain, which will kill many of the crops as well. Not having enough food will cause major health problems to billions of people. Also, the air that we breathe will be full of carbon dioxide. This could cause people to obtain hypercapnia, “the physical condition of having the presence of an abnormally high level of carbon dioxide in the circulating blood” (WordNet). Food and oxygen are absolute necessities, and without them we will not be able to survive.
“Limited land will also be a problem. In a matter of years when global warming has melted most of the glaciers, the sea level will rise quite a considerable amount, causing certain parts of America, Canada, and the rest of the world to be completely under water” (Lavin). Many families, as well as the general population all over the world will be forced out of their homes and will not have much to turn to. “Iceland is losing its ice, and it's not alone. Greenland's 10,000-year-old ice sheet is retreating at a rate that has astonished scientists who study it. Arctic Ocean sea ice has shrunk by 6 percent since 1978, while the average thickness has declined by 40 percent in recent decades, threatening polar bears, seals and the Inuit people who hunt them (Woodard).” Those areas will no longer be suitable to live in. Other places may have droughts, floods, or abnormally altered weather patterns. There will not be enough land that is suitable. It will be extremely over-overcrowded, and there simply wouldn’t be enough room for everybody.
The most obvious thing that’ll be hard to deal with is the violent level of heat that humans would be forced to live in. At this point, air conditioning would only be available to the very rich, snow is probably already forgotten, and the idea of “going...
