Discover the impact of the human footprint in "The World Without Us". Take us off the Earth and what traces of us would linger? And which would disappear? Alan Weisman writes about which objects from today would vanish without us; how our pipes, wires, and cables would be pulverized into an unusual (but mere) line of red rock; why some museums and churches might be the last human creations standing; how rats and roaches would struggle without us; and how plastic, cast-iron, and radio waves may be our most lasting gifts to the planet. But "The World Without Us" is also about how parts of our world currently fare without a human presence (Chernobyl; a Polish old-growth forest; the Korean DMZ) and it looks at the human legacy on Earth, both fleeting and indelible. It's narrative non-fiction at its finest, taking on an irresistible concept with gravity and a highly-readable touch. Some examples of what would happen are: One year: Several more billion birds will live when airplane warning lights cease blinking; Twenty years: The water-soaked steel columns that support the street above New York's East Side would corrode and buckle. As Lexington Avenue caves in, it becomes a river; 100,000 years: CO2 will be back to pre-human levels (or it might take longer); Forever: Our radio waves, fragmented as they may be, will still be going out.
