As does every other life form, given the chance. We are the only one, that we know of, which even has a concept of conservation. We have the power to consciously regulate our behavior.
In the end, my point is that either life is valuable for its own sake, including humans, or it isn’t, including the rest of the ecosystem. Any philosophy which posits that the existence of other life forms is more valid than that of humans is foundationally inconsistent. I’m certainly not saying that human life is more valid than others, but either life is valid or out isn’t. Humans aren’t special one way or the other.
