It’s hard for an evolutionist (I am one of them) to hold the anthropocentric view of life. In serious hard evolutionism there is some form of kinship between all living beings (plants included) and no intrinsic (or ontological) superiority of humans over the rest of the “creation” (this term is not appropriate here, evolutionism rejects the idea of a creator). But why should we worry so much about the extinction of some species, if the only important species is the human species? Though this is not explicitly stated even by hardcore defenders of biodiversity, the defense of biodiversity makes sense only if we assign to evolutionist solutions a superiority over mechanical, technical solutions to the problems of reaching some goals. Movement via wings, e.g., is superior to movement via jets, motors and wheels. Sometime jets, motors and wheels will disappear from the planet. Wings and limbs will again reestablish their primacy.
