Reviving Extinct Species

some creatures are dead for a reason.

why not?

it useless to do it. even if we revive a species, it may look the same but it wouldn't have the exact same behaviour as it did before, so what's the point?

They had their time on their planet, its time for new ones.

creatures that are extinct should stay that way, its now time for new ones to come. and what would be the point of reviving extinct creatures just so that we humans hurt them more with global warming?

let them rest in peace.
