A 2015 study funded by the Natural Environment Research Council found “abundant wildlife populations” in the zone, suggesting that humans are far more of a threat to the local flora and fauna than 30 years of chronic radiation exposure. The speed at which nature reclaims a landscape depends a lot on the climate of an area. In the deserts of the Middle East, ruins from thousands of years ago are still visible – but the same can’t be said of cities only a few hundred years old in tropical forests. In 1542, when Europeans first saw the rainforests of Brazil, they reported cities, roads, and fields along the banks of major rivers. After the population was decimated by diseases that the explorers brought with them, however, these cities were quickly reclaimed by the jungle. The ruins of Las Vegas are certain to persist far longer than those of Mumbai.
