It might be a good time to starting curbing your sushi addiction: A shocking new study from the University of British Columbia reveals that global fishing has been drastically underestimated and there are way less fish in the ocean that previously believed, notes the BBC. According to researchers, “the amount of fish taken from the world’s oceans over the last 60 years has been underestimated by more than 50 percent.” The researchers also argue that 32 million tons of fish are unreported each year, which is equal to more than the “weight of the entire US population.”

So how did all of this under reporting occur? Researchers say that the figures submitted to the UN’s Food and Agricultural Organization (FAO) are basically only from large industrial fishing operations. The figures rarely include figures from “small scale fisheries,”and independent fishermen, as well as illegal fishing. The researchers say the reason catches across the world are steadily declining each year is because the supply of fish has been depleted and not reported.

This isn’t the only challenge the seafood industry if facing. Last year, actress Helena Bonham Carter posed naked with a giant tuna to help raise awareness about overfishing. Fishlove, the organization behind the campaign, notes on its website that the global marine ecosystem “will collapse within a generation if unsustainable fishing practices are allowed to continue.”
