The author and the lecturer hold a set of conflict opinions about ethanol fuel. The author claims that ethanol fuel is not a good alternative for gasoline, while the lecturer refutes this opinion.
Firstly, the reading passage states that burning ethanol fuel will not relieve global warming, for burning ethanol fuel releases carbon dioxide into the atmosphere. However, the listening material opposes this statement by claiming that ethanol fuel come from plants. The growth of plants absorbs carbon dioxide from the air, thus counteracts the release of the gas when ethanol fuel is burned.
Secondly, the writer proposes that animals' sources of food may decline when ethanol fuel are commonly used. However, the speaker casts doubt on this opinion by mentioning that ethanol fuel can be made from a chemical which exists in plant cell walls. This chemical will not be eaten by animals, therefore popularizing ethanol fuel will not result in a decrease of animal feeds.
Thirdly, the article asserts that ethanol fuel will be outcompeted by gasoline in terms of price, because tax subsidies are given to ethanol producers by the American government, which is only a temporary method to keep the balance between the gasoline's and the ethanol's price. By contrast, the professor believes that this claim does not hold water. As ethanol grows increasingly popular, the production of ethanol will become massive, which leads to the decrease of the ethanol's price. To be more specific, it is estimated that three times of production will cause a forty percent drop of price. Thus the price of ethanol will not be a problem.
