This New York Times story about the threat to Antarctica’s krill is quite alarming. Laboratory research is showing that krill eggs can’t survive increases in carbon dioxide, a condition that mimics the acidification of the ocean due to global warming. Dr. So Kawaguchi has been studying krill for 25 years, and as the Times notes, 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.”
In fact, Kawaguchi told the Times: “If we continue with business as usual, and we don’t act on reducing carbon emissions, in that case, there could be a 20 to 70 percent reduction in Antarctic krill by 2100…By 2300, the Southern Ocean might not be suitable for krill reproduction.”
Krill are already being vacuumed from the sea by commercial fishing trawlers and used to feed farmed fish as well as for oil supplements for humans. And these activities take food from the mouths of those who need krill the most: whales and penguins, sea birds and squid.
For the fifth year in a row, the Commission for Conservation of Antarctic Marine Living Resources (CCAMLR) is discussing the creation of a Marine Protected Area (MPA) in the Antarctic. At 1.25 million square kilometers, it would be the biggest MPA in the world.
Meanwhile, we can all do our part — by avoiding farmed seafood that depletes the Antarctic krill (and if you need further inspiration to give up farmed fish, this post on the conditions in which farmed fish are raised should do it), and also by choosing plant-based supplements, which helps protect all creatures, which in turn helps protect us. As Sea Shepherd founder Paul Watson is known for saying, “If the oceans die, we die.” And he is right.
