Mining the Sky & Space Tethers to achieve LEO

By the same argument though we can say by altering the natural
environment, putting stress on the life forms that lived there to
evolve into better more adaptable animals.

Yes, humanities action has decreased the biodiversity of the planet,
but we too are part of the biosphere. If other creatures can't adapt
to us perhaps they should go extinct. Similarily if we can't adapt to
other creatures maybe we should go extinct.

I don't know what stats you have seen but the natural extinction
events took out 50-90% of all species on the planet. I doubt were
anywhere that high. Remember our growth took a thousand years it
wasn't a catastrophic event. The organisms we affected directly or
indirectly had time to change or migrate away.
