After being almost wiped out by whaling in the 20th century, a humpback whale population off the coast of South America has come back from the brink of extinction. In the late 1950s there were only 440 western South Atlantic humpbacks left. Protections were put in place in the 1960s. At first they didn't seem to be rebounding, but a study published Wednesday finds that to the surprise of scientists the population is now up to an estimated 25,000 whales. That's almost as many as researchers estimate there were before whaling began in the 1700s. Scientists were thrilled to realize how fast and how well the population has recovered after whaling finally stopped for good in the 1970s. This is a clear example that if we do the right thing then the population will recover, said Alexandre Zerbini, a whale expert with the Seattle Marine Mammal Laboratory of the National Marine Fisheries Service. The scientists estimate the humpbacks are at about 93% of their pre-whaling population. The research was published Wednesday in the journal Royal Society Open Science, a peer-reviewed scientific journal. There are 16 populations of humpbacks around the world. Four of them are considered endangered and one is threatened. The global population has been rebounding since whaling was banned in the 1970s. It's estimated there are currently between 120,000 and 150,000 humpbacks.
