Final answer:
Leopold's land ethic suggests that adopting an ecocentrism view, where humans are members of the land-community respecting all its components, is ecologically necessary and evolutionarily possible.
Step-by-step explanation:
According to Aldo Leopold's land ethic, it is an ecological necessity and an evolutionary possibility for humans to adopt an ecocentrism view (Option C). Leopold's concept emphasizes that humans should consider themselves not as conquerors but as plain members and citizens of the land-community. This view is supported by the belief that all parts of the natural world have intrinsic value, regardless of their utility to humans, which is a shift from the traditional anthropocentric perspective that places human interests above those of the natural environment.
