The badly endangered blue whale species has returned to South Georgia after 50 years of whale hunting. From ten thousands of blue whales in the region, now it has decreased to almost none. The team is studying how blue whales continue to recover after the stop on whaling in the 1960’s, where more than 42,000 whale huntings happened. Earlier this year, a record of 58 blue whale sightings and sound monitorings were detected. The research team hopes that increased numbers of blue whales are signs that the research can help to the good management of the area. Scientists said that blue whales contribute to the growth of phytoplankton which is a food source for other species. This marked the start of the recovery of blue whales, which were once thought to never be found in the area again.
