As symbols of the freedom of the wilderness, bald eagles have the unique capacity to inspire people and foster in them a sympathetic attitude toward the needs of other threatened species. Clearly, without that sympathy and the political will it engenders, the needs of more obscure species will go unmet. The conservation needs of many obscure species can only be met by beginning with the conservation of this symbolic species, the bald eagle. Which one of the following is the main point of the passage as a whole? ["People's love of the wilderness can be used to engender political support for conservation efforts.", 'Without increased public sympathy for conservation, the needs of many symbolic species will go unmet.', 'The conservation of bald eagles is the first necessary step in conserving other endangered species.', 'Because bald eagles symbolize freedom, conservation efforts should be concentrated on them rather than on other, more obscure species.']
