The World Without Us is a 2007 non-fiction book about what would happen to the natural and built environment if humans suddenly disappeared, written by American journalist Alan Weisman and published by St. Martin's Thomas Dunne Books. It is a book-length expansion of Weisman's own February 2005 Discover article "Earth Without People". Written largely as a thought experiment, it outlines, for example, how cities and houses would deteriorate, how long man-made artifacts would last, and how remaining lifeforms would evolve. Weisman concludes that residential neighborhoods would become forests within 500 years, and that radioactive waste, bronze statues, plastics, and Mount Rushmore would be among the longest-lasting evidence of human presence on Earth. The author of four previous books and numerous articles for magazines, Weisman traveled to interview academics, scientists and other authorities. He used quotations from these interviews to explain the effects of the natural environment and to substantiate predictions. The book has been translated and published in many countries. It was successful in the U.S., reaching #6 on the New York Times Best Seller list and #1 on the San Francisco Chronicle Best-Sellers list in September 2007. It ranked #1 on Time and Entertainment Weeklys of 2007. Background The idea of exploring the effects of the depopulating of the Earth is an old one, having been a regular trope in science fiction novels for decades. Post-apocalyptic literature in general had often tried to imagine the fate of civilization and its artifacts after the end of humanity. Indeed, an extremely popular 1949 novel, Earth Abides, portrayed the breakdown of urban systems and structures after a pandemic, through the eyes of a survivor, who muses at the end of the first chapter: "What would happen to the world and its creatures without man? That he was left to see." The World Without Us applies a more ecological view to Earth Abides. Before writing it, the author, Alan Weisman, had written four books, including, Gaviotas: A Village to Reinvent the World, in 1998, about the eco-village of Gaviotas in Colombia; and An Echo In My Blood, in 1999, about his family's history immigrating from Ukraine to the United States. He has worked as an international journalist for American magazines and newspapers, and at the time of writing the book was an Associate Professor of Journalism and Latin American Studies at the University of Arizona.
