abstract:What if? In his extraordinary book, The World Without Us (Thomas Dunne Books/St. Martin’s Press 2007) Alan Weisner asks the question, “What if?” Imagine a world where suddenly humans didn’t exist, where we had suddenly vanished leaving the world as it is now. What would we leave behind? What would the world inherit from our existence? How quickly would nature take back the land we have borrowed? Do you think the Eiffel Tower would still be standing one thousand years from now, would the Panama Canal still be intact, would the Euro Tunnel have caved-in? Weisner takes the reader all over the world exploring different places and the effects we have had on them, and what effects we have set in motion for the future.
