Industrialist: Environmentalists contend that emissions from our factory pose a health risk to those living downwind. The only testimony presented in support of this contention comes from residents of the communities surrounding the factory. But only a trained scientist can determine whether or not these emissions are dangerous, and none of the residents are scientists. Hence our factory' s emissions present no health risk. The reasoning in the industrialist's argument is flawed because the argument ['equivocates between two different notions of the term "health risk"', 'presents no testimony from scientists that the emissions are safe', 'fails to discuss the benefits of the factory to the surrounding community', 'does not consider the safety of emissions from other sources in the area']
