Why should it? The environment is there for the benefit of humanity. When preserving it helps people, preserve it. When it doesn't, don't. It makes no sense to value ecological responsibility in itself divorced from human interests.
I don't agree with that. Humans are just one participant in the environment and we should respect the others.
My viewpoint is that those who are quick to trample on the weakest, including endangered animals, will likely find it easy to trample on the rights of the poor. It is not in my interest to support that potential future where might makes right. Both my interests and non-human interests can be served at the same time, with no conflicts if viewed in the long term.
