单选题 1 Alligators have no natural predators except humans. In fact, humans drove alligators to near extinction in many of their marsh and swamp habitats in North America. Hunters once killed large numbers of these animals for their meat and soft belly skin, which was used to make shoes, belts, and wallets. Between 1950 and 1960, hunters wiped out 90 percent of the alligators in Louisiana and greatly reduced the alligator population in the Florida Everglades.
2 In 1967 the federal government placed the American alligator on the endangered species list. In the next decade, protected by hunters and averaging about 40 eggs per nest, the alligator made a strong comeback. It was reclassified from endangered to threatened in Florida, Louisiana, and Texas, where the vast majority of the animals live. As a threatened species, it is still protected from excessive harvesting by hunters; however, limited hunting is allowed in some areas to keep the population from growing too large.
