【正文】 down. Trees fall over. Large holes form in the ground. Could Alaska be sinking? That’s what some villagers in Alaska have been asking themselves recently and scientists think they know why. Warmer temperatures may be causing Alaska’s frozen ground to thaw(解凍)．About 85 percent of Alaska’s land surface has permafrost(永久凍結(jié)帶). Permafrost supports the ground above it—including trees, houses, and roads. But why is the permafrost thawing?Some scientists say that human－caused pollution is leading to global warming. And most scientists agree that Alaska has been getting warmer. They say that the warmer temperature is causing permafrost to thaw in some areas. The thawing permafrost can cause problems for people, plants, and animals.The collapsing(倒塌)is a problem in the villages in Alaska which are built on permafrost, and some of them may have to move to safer ground, where there is no permafrost.The Alaskan town of Glennallen saw its old post office collapse. And, according to James Walters, a permafrost expert at the University of Northern Iowa, house－moving panies have been very busy.“Melting permafrost can also destroy trees and forests，” Walters said. “When holes in the ground form, trees fall into them and die. This could turn a forest into a swamp(沼澤), and animals which need the forests will have to move elsewhere.”The melting could cause severe problems. Walters said, “This could take hundreds of years, but in the end Alaska will look quite different from what it looks like now.”72．Which of the following can be used as the best title of the passage?A.
