Final answer:
E.O. Wilson relates the significance of biodiversity directly to readers' lives and refers to empirical examples to emphasize the practical and ethical importance of preserving biodiversity.
Step-by-step explanation:
In the excerpt from E.O. Wilson’s “The Environmental Ethic,” Wilson uses a variety of techniques to convey important information to his readers. He primarily relates the significance of the information directly to the reader’s life by illustrating the tangible benefits that biodiversity provides, such as medicines, crops, and other valuable resources that have been sourced from a diverse range of species. Moreover, Wilson refers to empirical and real-world examples, such as the use of chemicals from salivary glands of leeches in medicine, to anchor his argument in established facts. These examples serve to illustrate the practical importance of biodiversity and its impact on human welfare, which ties into ethical considerations regarding conservation and environmental responsibility. This approach is aligned with the broader conservation ethos advocated by figures such as Aldo Leopold and Rachel Carson, emphasizing humanity's ethical duty to preserve natural diversity.
