the Korean Federation for Environmental Movement at the Korean Demilitarized Zone where few humans have penetrated since 1953. He tries to conceive how life may evolve by describing the past evolution of pre-historic plants and animals, but notes Douglas Erwin's warning that "we can't predict what the world will be 5 million years later by looking at the survivors". Several chapters are dedicated to megafauna, which Weisman predicts would proliferate. He profiles soil samples from the past 200 years and extrapolates concentrations of heavy metals and foreign substances into a future without industrial inputs. Carbon dioxide levels in the atmosphere and implications for climatic change are likewise examined. With material from previous articles, Weisman uses the fate of the Mayan civilization to illustrate the possibility of an entrenched society vanishing and how the natural environment quickly conceals evidence. To demonstrate how vegetation could compromise human built infrastructure, Weisman interviewed hydrologists and employees at the Panama Canal, where constant maintenance is required to keep the jungle vegetation and silt away from the dams. To illustrate abandoned cities succumbing to nature, Weisman reports from Chernobyl, Ukraine (abandoned in 1986) and Varosha, Cyprus (abandoned in 1974). Weisman finds that their structures crumble as weather does unrepaired damage and other life forms create new habitats. In Turkey, Weisman contrasts the construction practices of the rapidly growing Istanbul, as typical for large cities in less developed countries, with the underground cities in Cappadocia. Due to a large demand for housing in Istanbul much of it was developed quickly with whatever material was available and could collapse in a major earthquake or other natural disaster. Cappadocian underground cities were built thousands of years ago out of volcanic tuff, and are likely to survive for centuries to come. Weisman uses New York City as a model to outline how an unmaintained urban area would deconstruct. He explains that sewers would clog, underground streams would flood subway corridors, and soils under roads would erode and cave in. From interviews with members of the Wildlife Conservation Society who developed the Mannahatta Project and with the New York Botanical Gardens Weisman predicts that native vegetation would return, spreading from parks and out-surviving invasive species. Without humans to provide food and warmth, rats and cockroaches would die off. Weisman explains that a common house would begin to fall apart as water eventually leaks into the roof around the flashings, erodes the
