What&#x27;s the point of preserving a lifeless environment or even one with bacteria and no intelligent animals, over giving humanity a second planet to survive on in case something happens on Earth?<p>After all, even here on Earth we haven&#x27;t had such a concern for species that are not us. We drove many to extinction even without it being an existential matter for us.<p>I think the human sense of morality is largely dependent on how similar something is to us, to know if we are even hurting it. How can you hurt a lifeless environment that&#x27;s the product of random, and sometimes cataclysmic, events?
