Mass extinctions can be caused by a relatively rapid change in the environment and can be worsened by the close interrelationship of many species.
As you're thinking of the consequence of that, if you believe that extinctions are common and natural and normal and occur periodically, it becomes a moral imperative to diversify our species.
