座头鲸在全球范围内浴火重生
When the Pacific Whale Foundation was founded in 1980, its researchers would drive up and down the coast of Hawaii waiting to see a whale. At that time, only a few hundred humpback whales made it to the islands per year. Now, more than 10,000 do. This recovery of the Hawaiian coast population is a sign of the species' worldwide comeback from the brink (边缘)of extinction, including a recently reported return of humpback whales near Antarctica.
