Due to the emissions from coal-fired power plants, oil refineries and cars, the Earth has warmed by 9 degrees Fahrenheit since the 1950s. The polar caps have lost about 30 percent of their ice mass since the 1970s. As a result, the oceans temperatures have steadily risen; consequently, causing bigger and more frequent hurricanes and typhoons. For this reason, some scientists argue that these are natural weather occurrences because the Earth is in a warming trend just before a new ice age. On the other hand, the majority of scientists are coming to an agreement that carbon dioxide or (CO2) emissions are the primary source of the Green House Effect, which is causing the current global catastrophes. Some of the ways to prevent global catastrophes is to find alterative energy sources. There are alternative sources of energy such as ethanol fuel, hydroelectric, nuclear, solar, and wind power. All these sources could replace fossil fuels; thus, decreasing the toxic CO2 emissions in the atmosphere. The use of alternate energy could slow or even reverse the Green House Effect.
The Green House Effect is caused from carbon dioxide or (CO2) being trapped in the atmosphere. This doesn’t allow for radiation cooling, thus raising the Earth’s average temperature one degree every ten years. The average level of carbon dioxide for the last 40,000 years has stayed about 200 parts per million. However, in the last hundred years with the introduction of cars and oil refineries, the level of carbon dioxide has risen to 368 part per million. This is almost a 30% rise in carbon dioxide. At the current rate of fossil fuel consumption, by 2100 the carbon dioxide levels will be at 540 to 970 parts per million. This will make the atmosphere toxic to breath, and will have serious effects on sustaining any plant life on Earth. Furthermore, the industrial revolution also has contributed its share of toxins in the last 200 years. The toxins from industries have added harmful gases such as methane, nitrous and chlorofluorocarbons. These gases further the process of global warming by creating a blanket of toxic air over the Earth. (342) Some of the ways to prevent this tragedy from continuing is to find alternatives to fossil fuels.
The first alternative to fossil fuel is nuclear power because nuclear power doesn’t admit any emissions in the atmosphere. However, nuclear power does have its skeptics because of the radiation leak at Three Mile Island in New York in the 1970’s, and the Chernobyl melt down in the Russian Ukraine during the late 1980’s.These accidents could have been prevented if both nuclear reactors had better management teams. Both incidents were caused by human operating error and cut backs in the nuclear power plant’s budgets. Tragically, 31 people loss their lives in the Chernobyl accident, but that is nothing compared to the thousands of people who have lost their lives in coal mining accidents mining coal for power plants.

Nuclear power can be safe and use less natural recourses to produce the same amount of power. For example, the New Madrid power station in
There are also other sources of energy such as windmills and solar panels. These sources may not always be reliable because of the weather. However, these renewable sources of energy are safe and clean for the environment. Windmills and solar panels could substitute for a natural gas substation such as the one on
The use of coal for electricity is only one of the problems in global warming. The other problem is the growing demand of oil and gas. In the last 50 years the population of Earth has doubled to six and a half billion people. As a result, the demand for planes and vehicles has also doubled; for this reason, planes and vehicles account for 21% of the total carbon dioxide in the Earth’s atmosphere. The gas used in cars and trucks account for the largest amount of carbon dioxide produced in the
To combat the ecological damage done from global warming, large oil companies and automobile manufactures must do more research and development in the production of ethanol. Ethanol is the cleanest burning fuel because it contains 35% oxygen by weight and is totally biodegradable. Fuels blended with ethanol drop the emission from cars by 35 to 45%; therefore, reducing the fossil fuel use by 50%. The blended fuel is equivalent of removing 853,000 cars annually from our nation’s highways. Furthermore, the use of ethanol in the
And last, Americans need to change their love affair with SUVs and Trucks to help in reducing the CO2 green house gas. The SUVs and Trucks account for 51% of all vehicles on
In closing, Mankind is at the top of the evolutional chain, so it’s Mankind’s conscious and moral responsibility to ensure the survival of all living species on Earth. One way to ensure the survival of the forests and the animals that live in them is to change people’s dependency of fossil fuels; this is done by finding alternative energy sources. Furthermore, people need more education on the effects of Global Warming. For if they knew the future catastrophes that come with Global warming, maybe it would change their minds on the damage they are inflecting on the Earth.
