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 tosolve 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.
The reading passage proposes three reasons why ethanol cannot be treated as a ideal substitute for gasoline. The profess, however thinks the reasons are not convincing. He justifies his conclusion with another three cogent arguments.
First of all, even though the reading passage maintains that the effect of global warming will continue because of released carbon dioxide by burning ethanol, the lecture argues that source of making ethanol is corn, the growing process of which is going to counteract global warming by absorbing greenhouse gas in the air.
Moreover, contrary to the statements in the brief reading that food supply for cattle will decrease as a result of taking a large amount of plant for ethanol, the professor' talk contends that raw materials for ethanol are some kinds of plants, which grow along side the walls, and these plants cannot be eaten by livestock.
Finally, although the author asserts that high price of ethanol may well lose competitiveness with gas without subsidiary from the U.S government, the professor just hold the opposite opinion that when production of ethanol get promoted the price is bound to get lower. He also estimate that price of new fuel will reduce 40 percent along with production amount becomes 3 times in the future.
