Final answer:
The best summary of E. O. Wilson's views is that the loss of species and habitats deeply affects both the environment and human progress, leading to the potential loss of invaluable biological assets and a dramatic impact on human welfare. The correct answer is option 4.
Step-by-step explanation:
Based on E. O. Wilson’s “The Environmental Ethic” excerpt, the statement that best summarizes the author’s beliefs about the disappearing species is that the loss of plant species and habitats will devastate animals and hinder human progress. The author argues that species extinction, primarily due to human activities such as habitat destruction, pollution, and the introduction of invasive species, leads to the loss of potential biological wealth and scientific information. This includes undeveloped medicines, crops, and other products crucial for human welfare, which are integral to the health and function of ecosystems.
The disappearance of species is not only a biodiversity crisis but also poses a significant threat to human life support systems. The accelerated extinction rate impacts human welfare by potentially leading to ecosystem collapse and increasing the costs associated with maintaining crucial services, such as food production, clean air, and water. The ecosystems' health is directly connected to human health, highlighting the imperative to halt the rate of species loss.
