Humans must cooperate, and make massive changes, or face the collapse of the biosphere; and our own extinction. Conservatives will obstruct, because they can't imagine another way. They will have to be defeated and controlled. Destructive linear systems will have to be dismantled or modified to be nondestructive circular systems.
Building circular systems that are sustainable and compatible with nature will not be easy. We have enormous investments in unsustainable linear systems.
