No, Capitalism will not make the Earth uninhabitable. It will kill very many things the longer it is part of our world, but you are subscribing to a liberal fatalist narrative that constructs the future as definitively destroyed because it does not resemble the world we live in. It's doomer shit that is painfully white.
How you got, "we don't need to end capitalism" I have no responsibility for. If I say it isnt infinitely powerful but must end as quickly as possible, what exactly do you think I'm advocating for?
