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 excerpt states that many critics argue that ethanol is not a good replacement for gasoline for several reasons, the author provides three reasons for support. However, the lecture's audio claims that there are a lot of problems with the author theories and he refutes each of them by stating that the cause of these arguments is not obvious.
To begin with, the article avers that the increased use of ethanol fuel would not help to solve one of the biggest environmental problems caused by gasoline use: global warming. In contrast, the professor opposes this point of view by saying that the ethanol will not add anything to the global warming and it is right that the burning of it will release carbonic dioxide. However, it is produced by the plants such as corn and these plants when grown, they will take the carbonic dioxide from the air. So, planting a myriad amount of plants to produce this gas will reduce this harmful gas from the environment. Consequently, this theory contradicts what the professor explained.
Second, the passage posits that the production of significant amounts of ethanol would dramatically reduce the number of plants available for uses other fuel. On the other hand, the speaker asserts this outlook and explains that the ethanol will not reduce the food resources for animals because they can use the cellulose which is the plants covering substance for ethanol production and this substance does not eat by the animals. Thus, this dispute the second point of the passage.
Third, the excerpt mentions that ethanol fuel will never be able to compete with gasoline on price. This cast doubt on what the lecturer argued which states that even if the ethanol will compete with the gasoline in price, people will use to use much ethanol which will lead to producing more amount of it and this will, in turn, make its price cheap. Thus, the cost of the ethanol will decrease by forty percent more as the production increase three times in the future. Thus, this idea of the author is definitely wrong.
