Whales are in danger from hunting too. In past times the Inuit people of Alaska hunted whales but they did not kill many. then hunters came from ohter countries in bigger ships and killed thousands. Antarctica was also a good place for whales. About 250,000 blue whales, the biggest animals in the world, lived there in 1900. Blue whales can live for ninety years. But in one year, 1930-1931, hunters killed 30,000, and today there are only about 5,000 of them.
