March 13, 2019 — A year after the critically endangered North Atlantic right whale population produced zero calves for the first time on record, the animals have given birth to seven calves so far this winter. But that number is still far too few to convince scientists that the population is rebounding.
“Without concerted efforts to reduce the effects of human activities, this species is likely to go functionally extinct in about 20 years,” Scott Krauss, senior science advisor at the New England Aquarium, said during testimony March 7 at a congressional hearing examining the threats to right whales.
The global population of North Atlantic right whales, which currently stands at about 400, was growing steadily in the 1990s and 2000s, including a record year in 2009 when 39 calves were born. But reproduction rates have slowed precipitously since then.
