Deaths from natural disasters have been dramatically decreasing for decades. The number of people we can feed on less land has been increasing for decades. The ability of humans to move resources from one place to another has been increasing for centuries. Some people choose to live in warm and dry places rather than cold and damp places.
You discount the ability of the planet to respond to feedback and achieve balance, and the ability of humans to adapt. You don't even need international cabals of authoritarian collectivists to live a happy life.
