(CNN) The devastating heat wave that ravaged British Columbia last week is being blamed for a massive die-off of mussels, clams and other marine animals that live on the beaches of Western Canada. Christopher Harley estimates that a billion mussels, clams and other animals may have died from the heat. "I started having a look around just on my local beach and thought, 'Oh, this, this can't be good.'" The next day, Harley and one of his students went to Lighthouse Park in West Vancouver, which he has been visiting for more than 12 years. "When we start seeing die-offs of other smaller animals, because they're moving around, because they're not so dense, It's not quite as obvious."
