Wind Farms

Large wind farms might interfere with the flight patterns of migratory birds in certain areas, and they have killed large birds of prey (especially hawks, falcons, and eagles) that prefer to hunt along the same ridge lines that are ideal for wind turbines. The killing of birds of prey by wind turbines has pitted environmentalists who champion wildlife protection against environmentalists who promote renewable wind energy. Researchers are evaluating how serious this problem is and hope to find ways to eliminate or sharply reduce this problem. Some analysts also contend that the number of birds killed by wind turbines is dwarfed by birds killed by other human-related sources and by the potential loss of entire bird species from possible global warming. Recorded deaths of birds of prey and other birds in wind farms in the United States currently amount to no more than 300 per year. By contrast, in the United States an estimated 97 million birds are killed each year when they collide with buildings made of plate glass, 57 million are killed on highways each year; at least 3.8 million die annually from pollution and poisoning; and millions of birds are electrocuted each year by transmission and distribution lines carrying power produced by nuclear and coal power plants.

In the paragraph, why does the author give details about the estimated numbers of birds killed each year?

a) To argue that wind farms should not be built along ridge lines.b) To point out that the deaths of migratory birds exceed the deaths of birds of prey.c) To explain why some environmentalists oppose wind energy.d) To demonstrate the number of birds killed by wind turbines is overestimated.e) To suggest that wind turbines result in relatively few bird deaths.
