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.
Both the reading and lecture discuss whether ethanol fuel, which made from plants such as maize and ratoon crops would be alternative to gasoline in America or not. The former argues that ethanol is not actually better for substitution with gasoline, and there are three possible reasons to doing so, but latter challenges each of these points.
First of all, the author of passage asserts that ethanol actually release carbon dioxide into atmosphere, if it burns for fuel, which lead to global warming. However, the professor of lecture contends that it does not hold true because presence of corns absorb the carbon dioxide from atmosphere and remove all carbon dioxide which is main cause of global warming.
Secondly, according to the passage, the expert opined that there will be dramatically diminishing in the fodder for farm animals, since corn plants use in other purpose such as producing ethanol, instead of growing for farm animals food. In contrast, the lecture objects this idea. He supports his argument by presenting the example of cellulose, which is actually use for production of ethanol. Indeed, expect cellulose of plants, other parts of plants would be available for farm animals to feed.
Finally, the passage claims that ethanol will never compete with gasoline, if government stop to give subsidies to producers which enhances the price of ethanol. Nevertheless, like two disadvantages before, the professor in his lecture proclaims that this method is not feasible because in future its price will be not pricey. As people grow corn and ethanol produced three times than today then it price will be reduced by 40%.
