“Giant blue-grey sei whales that vanished from Argentina’s Patagonian coast a century ago due to hunting are starting to flourish once again, demonstrating how species can recover when measures to protect them are put in place.

In the 1920s and 1930s regular whaling ships along the shores of Argentina, and beyond, saw populations dwindle. In the last 50 years, global bans on commercial whaling have helped populations of sei and others revive.”
