Efforts to save the 3½-year-old killer whale J50 are failing. (Katy Foster/NOAA Fisheries)What's the argument against doing everything possible to save J50? Is it worthwhile spending lots of resources on individual animals when it's really the population we need to be focusing on and threats to the population? And if there is an individual animal in a population that's going to have the biggest positive impact on the persistence of that population, it's an adult female. It's adult females that really make populations grow and that's what we're talking about with J50.
