A powerful investigation into the chances for humanity´s future from the author of the best seller The World Without Us. In his best-selling book The World Without Us, Alan Weisman considered how the Earth could heal and even refill empty niches if relieved of humanity´s constant pressures. Behind that groundbreaking thought experiment was his hope that we would be inspired to find a way to add humans back to this vision of a restored, healthy planet - only in harmony, not mortal combat, with the rest of nature. But with a million more of us every four days on a planet that´s not getting any bigger, and with our exhaust overheating the atmosphere and altering the chemistry of the oceans, prospects for a sustainable human future seem ever more in doubt. For this long awaited follow-up book, Weisman traveled to more than 20 countries to ask what experts agreed were probably the most important questions on Earth - and also the hardest: How many humans can the planet hold without capsizing? How robust must the Earth´s ecosystem be to assure our continued existence? Can we know which other species are essential to our survival? And, how might we actually arrive at a stable, optimum population, and design an economy to allow genuine prosperity without endless growth? Weisman visits an extraordinary range of the world´s cultures, religions, nationalities, tribes, and political systems to learn what in their beliefs, histories, liturgies, or current circumstances might suggest that sometimes it´s in their own best interest to limit their growth.
