Ps Unless humans change there ways who’s to say who God will save. When he was revering in Mathew he must end it before there’s nothing left to save he was obviously not talking about the lions tigers and bears, but humans, the most dangerous and still ignorant in their actions, creatures on earth. It didn’t say humans of the earth, it said woe to the inhabitants of the earth of both land and sea.
As far as over population I don’t see these over populated areas cooperating any time soon, especially when they have incentives by the corrupt to encroach on less populated areas.
