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 a 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 States 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 the producers in this way, the price of ethanol would increase greatly.

The lecture casts doubt on the passage that ethanol is not a good replacement for gasoline. Instead, the professor believes that ethanol fuel is a great replacing fuel for gasoline.

First of all, the passage claims that since ethanol releases carbon dioxide when it is burned for fuel, and carbon dioxide is a greenhouse gas, the increased use of ethanol fuel would not help to solve global warming However, the professor refutes the passage by arguing that burning ethanol will not add to global warming. This is because ethanol is made from plants, and plants can absorb carbon dioxide, which counteract with carbon dioxide that released from burning ethanol.

Secondly, the passage states that the production of significant amounts of ethanol would dramatically reduce the amount of plants available for uses other than fuel. Yet the professor disagrees with the statement by mentioning that ethanol is usually made from cellulose, which is the part of a plant that animals do not eat. Thus, production of ethanol will not reduce animals' food supply.

Finally, the passage argues that ethanol fuel will never be able to compete with gasoline on price, because the price of ethanol is currently helped by the United States government. If the United States government stop helping the producers, the price of ethanol would increase greatly. Nevertheless, the professor denies the passage by pointing out that if there are enough people buying ethanol, since more production will lead to the decrease in price, ethanol will be able to compete with the gasoline on price. And the professor cites a report study, which claims that if the production of ethanol grows three times more, the unit price of ethanol will drop forty
