15. Repopulation Of Whales Is Very Slow
The hunting of Antarctic Blue whales was banned in the Atlantic Ocean during 1964. Numbers in 1926 were estimated to be 126,000 adult whales.
Whaling in the Atlantic Ocean had reached such extents that whales were almost driven to extinction. After a moratorium to ensure their survival and limit whaling were passed, whales started to recuperate.
It is astonishing but according to the last estimation, the number of Antarctic Blue whales has only been able to reach 3000 in 2018. This only illustrates the long-lasting effects extreme hunting has on whales and the ecosystem they inhabit.
