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 than 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 is about ethanol is not a good alternative for gasoline. It provides three supporting ideas in order to bolster its claim. But, the speaker says, ethanol will be a good replacement of gasoline. He refutes each of the reading claim.
First, the article asserts that using ethanol will intensify global warming. However, the lecturer denies this claim. He describes, global temperature will not rise for ethanol because plants will counteract to release carbon dioxide. As result, plant helps to remove the carbon dioxide and keep the temperature stable.
Second, the written excerpt states that, ethanol use will reduce available use of plants to use as food source. But, the professor refutes this and he explains, as the plant part cellulose is not eaten by animals and it is optional. So, using these part will not a bad choice. And food availability for animals will not reduce.
Third, the reading claims that, the cost of ethanol is high. The point is not convincing with the lecturer. The professor agreed that government tax subsidies is quite helpful to cut the ethanol production cost. But, he explains, when people buy enough ethanol, it will helps to downgrade the production cost. Moreover, he says by citing a study, where it was found, when production occurred three times, in return the market cost was down to 40 percent of that cost.
