You make your point very clearly - you would rather live in an apocalyptic world than give up your meat.
We know this. In fact, we know most humans like yourself won't give up anything at all to avoid destroying our ecosystem and with it, all the futures of all our children.

Psychopaths used to at least keep their antisocial personalities hidden, but now apparently you folks have absolutely no shame.
