“If the paper from every morning edition of the nation’s largest newspaper were collected and rendered into paper pulp that the newspaper could reuse, about 5 million trees would be saved each year. This kind of recycling is unnecessary, however, since the newspaper maintains its own forests to ensure an uninterrupted supply of paper.” （argument)
First of all, the arguer assumes that the only standard for evaluating whether recycling is unnecessary is whether the newspaper maintains its own forest to ensure an uninterrupted supply of paper; however, the arguer does not provide any evidence to prove such assumption.
Second of all, even we accept the assumption mentioned above, the arguer still fails to convince us that the forests maintained by the newspaper could ensure an uninterrupted supply of paper in the future.
Last but not least, even we accept both hypotheses above, the aruger still fails to consider other factos that could have influence on this decision, such as political reasons. (这一段纯粹是凑数了 哈哈)
