A powerful investigation into the chances for humanity's future from the author of the bestseller The World Without Us.

In this bestselling book, Alan Weisman considers how the Earth could heal if relieved of humanity’s constant pressures. But with a million more of us every 4 ½ days on a planet that’s not getting any bigger, prospects for a sustainable future seem doubtful.

Weisman traveled to more than 20 countries, to ask what experts agreed were incredibly important questions about Earth and our continued existence on this planet. The result is a landmark work of reporting: devastating, urgent, and ultimately, deeply hopeful.*
