Once on the verge of going extinct, humpback whales are now thriving in the South Atlantic
In the mid 1950s, humpback whales faced a serious threat of extinction as less than 450 of the species swam in the South Atlantic Ocean at the time. Their numbers plummeted greatly after whale hunting began in the western South Atlantic around 1830.
However, the good news is that the whales have recovered strongly and today, an estimated 25,000 humpback whales swim in the western South Atlantic.
This rebound may be part of a global trend for humpbacks. With commercial whaling first curbed and then eventually banned in 1986, the population began to recover.
