Canada heatwave cooks up to one billion shellfish alive

DW News shows that the Canadian province of British Columbia registered all-time record temperatures this summer. Hundreds of people died in connection with the extreme heat. And the impact on ecosystems was devastating: Scientists say up to a billion shellfish may have perished.

It seems that Bays in Western Canada are normally ideal for shellfish. They thrive in the secluded, nutrient-rich waters. But mussels and clams don't do well in extreme heat. And the region's recent heatwave has literally cooked them alive.
