In his new book, "The World Without Us," Alan Weisman is the tour guide for an amazing trip, one in which humans suddenly no longer exist. The built infrastructure - our homes and other structures, roads, dams, material wealth, art, farms and ranches - and everything we created will immediately start to give way to the relentless onslaught of sun, rain, wind, growing plants and insects.
Weisman, a noted environmental reporter and an associate professor of journalism at The University of Arizona, interviewed scores of scientists and engineers and assembled a timeline of how our physical legacy would decompose without our constant stewardship. The book has been on the New York Times bestseller list since mid-July, and Weisman has been promoting it on tour this fall. He is scheduled to teach a UA class on international journalism in the spring semester in Brazil.
