Is wild salmon almost extinct?

    Wild salmon in the Broughton Archipelago, off the west coast of Canada’s British Columbia, will be extinct within 10 years due to parasite contamination from fish farms, according to a study published in the journal Science.

    Researchers compared the population numbers of different groups of salmon between 1970 and the present, depending on whether they had been exposed to aquaculture salmon farms or not. Using a computer model of population change over time, the researchers were able to show that exposure to fish farms was causing population growth of wild salmon to be “severely depressed.”
