A Q&A With The Author Of "The World Without Us"
Don't worry about the Earth, author Alan Weisman says -- it will get on fine without us. In "The World Without Us," the author has imagined the world without humans, and -- despite a pervasive footprint on every continent that has made some dub this geologic era the Anthropocene, or age of humans -- the Earth's wildlife will quickly overtake our most prized works and come to a new state of balance in our wake. It's an interesting fantasy, one that raises extraordinary questions about humans' place in nature. Scientists have dubbed this era the Anthropocene precisely because our stamp on the Earth's ecosystems is so pervasive. Surely the world's life would continue -- albeit very differently from its current state. And life, as imagined in a post-human era, is no less resilient today ... and there are some telling examples of life that may not survive this era to re-emerge at a later date.
