So what is overfishing, really?
Basically, it's when we catch fish faster than they can have babies. And it's not just about running out of fish for dinner — whole ecosystems collapse, coastal towns lose their jobs, and the 3 billion people who count on the sea for food are left with nothing.
Industrial trawling
Bottom trawlers drag weighted nets across the seafloor, flattening centuries-old habitats in a single pass. A single trawl can release as much carbon as global aviation in a year.
Bycatch
For every kilogram of shrimp caught, up to ten kilograms of other animals die in the net — sharks, dolphins, turtles, juvenile fish — and are dumped overboard.
IUU fishing
Illegal, unreported and unregulated fishing accounts for up to one in five fish sold worldwide, undermining sustainable fleets and stripping developing nations of food and income.
Subsidies that destroy
Governments pour roughly $22 billion a year into fuel and capacity subsidies that keep oversized fleets at sea — often fishing waters that should be left to recover.
What SDG 14 says about it
Targets 14.4 and 14.6 are the ones that matter here. They tell countries to stop overfishing, rebuild fish populations, and scrap the subsidies making it worse. In 2022 the WTO actually agreed to do this — but whether they stick to it is another story.
