There aren’t plenty more fish in the sea.
The race is on to save sharks and other key marine species – including swordfish, marlin, monkfish andCskates/rays – from being wiped out by overfishing.C73,000,000 sharks are slaughtered every year.CThat’s around 200,000 sharks a day. Or roughly twoCevery second. Unless something changes, sharksCcould become a thing of the past. We’re not going to let that happen.
Choking to death
Sharks have been swimming in the oceans since before dinosaurs walked the earth. They’ve shaped the marine environment and everything in it. Without sharks the oceans could collapse, taking with them their ability to produce 50% of the oxygen we breathe and absorb 20% of the CO2 emissions we produce. With every shark slaughtered we’re strengthening our stranglehold on the planet.
Too many fishing boats, too few fish The International Union for the Conservation of Nature recently reported that 85% of the world’s fish stocks are fully exploited or overexploited. It’s the big fish that will disappear first.
That’s why we’re focussing on key species that are most vulnerable to overfishing yet widely available in shops and restaurants. Join us and help protect our blue planet.
