Overfishing is happening all over the world

Fish are in trouble.The cod population off Canada's East Coast collapsed in the 1990s,intense recreational and commercial fishing has decimated goliath grouper populations in South Florida,and most populations of tuna have plummeted by over 50%,with the Southern Atlantic bluefin on the verge of extinction.Those are just a couple of many examples.Overfishing is happening all over the world.How did this happen?When some people think of fishing,they imagine relaxing in a boat and patiently reeling in the day's catch.But modern industrial fishing,the kind that stocks our grocery shelves,looks more like warfare.
