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.
In the lecture,the lecturer casts doubts on the three points provided by the reading passage to assert that the ethanol as a fuel will not convenient as gasoline. The lecturer asserts that none of them provide a satisfactory point.
Firstly, according to the reading passage, the use of ethanol as a fuel will not add to the solution of the environmental crisis since it's burning also produce a huge amount of carbon dioxide. However, the lecturer disputes the point. He says that since ethanol is produced by the tree so if the use of it as a fuel will cause to produce more and more cane tree which eventually absorbs more amount of carbon dioxide thus established a balance which is far better then the use of gasoline
Secondly, on contrary to the reading passage that claims that, since the cane tree is a good food source to the cattle and other farm animals so it's used as fuel production will have a negative impact of the farm industry. Nevertheless, the lecturer refutes the point. He argues that large scale of production and using a new technique eg cellulose farming will not only provide food to the farm but also add to the fuel requirement.
Finally, the reading claims that the use of ethanol as fuel will increase its market price comparing to gasoline. On the contrary to this point, the lecturer claims that if the production will increase in a large scale amount then this will not happen. In order to bolster this point, he shows statistics that if the production of ethanol increase to 3 % the price will drop to about 40 % which is very much advantage to the use of ethanol as fuel instead of gasoline.
