high pregnancy failure in killer whales in Puget Sound

A multi-year survey of the nutritional, physiological and reproductive health of endangered southern resident killer whales suggests that up to two-thirds of pregnancies failed in this population from 2007 to 2014. The study links this orca population’s low reproductive success to stress brought on by low or variable abundance of their most nutrient-rich prey, Chinook salmon.

Professor Chu hypothesises that we will exceed 600ppm of carbon and that excludes the forcing of all the other green house gases including methane. That is unsurvivable btw
