Even if the 1st world is destroyed by its own avarice and technology, I believe that ancient tribes: The Aborigines, The San, The Pygmies, The Tupi, etc… will be the last havens for the human race; and rightfully so. 60,000 years of real survival experience and none of the bullshit us “civilized” folks waste time exalting, like iphones, Kardashians and Black Friday deals.
