Recent research has led to dire predictions about how global carbon emissions will significantly reduce the hatch rates of Antarctic krill over the next 100 years with implications for the whales, penguins and fish that feed on it . Krill, typically about the size of a pinkie and similar in appearance to shrimp, are one of the most abundant animal species on earth, and a cornerstone of the Antarctic ecosystem. 7 years ago So Kawaguchi, in his laboratory on the edge of the Southern Ocean, has been studying krill for 25 years. His recent research has led to dire predictions about how global carbon emissions will significantly reduce the hatch rates of Antarctic krill over the next 100 years.“Carbon dioxide levels increase the deeper you go; “Krill eggs are inanimate. As they sink, they can’t avoid areas of greater acidity.”
