"Over the past 20 years, krill fishing has quadrupled," says Kerdavid, "mainly to produce non-essential products like Omega-3 supplements, pet food, and feed for farmed salmon - used to make the flesh pink for Western supermarkets. A single trawler can catch up to 500 tonnes of krill per day. That's enough to feed 150 whales. Less krill means less food for whales, seals, penguins, and countless other species. Today, krill extraction is one of the fastest-growing threats to Antarctic wildlife. That’s why Sea Shepherd is heading to Antarctica: to expose this industry and show the world what’s really happening: hungry whales following krill trawlers, desperately searching for food."
