Can’t have it both ways; they’re also saying it will lead to human extinction.

If a broad enough war could be initiated, it could lead to human extinction.
But any war in which that much destruction is unleashed, probably would wipe out the cockroaches also, and isn’t the whole aim of the environmentalists, to preserve the habitat of earth for the perpetual occupancy by cockroaches?
Certainly isn’t to make earth hospitable to humanity.
Earth is WAY overdue to have an asteroid the size of Texas slam into the Indian Ocean (then we’ll NEVER find out what happened to Malaysian Flight 370).
