The future of marine life is in our hands Credit: Moment RF It’s the surprise documentary hit of the year so far, confrontational in style, shocking in content, and raising hackles across the food and scientific community. Netflix’s Seaspiracy tells it baldly: our oceans are heading for disaster, and it’s our fault. The film dwells on blood-drenched scenes of dolphin slaughter and sharks stripped of their fins, but at the core of the problem is more mundane overfishing. Years of industrial-scale trawling, dodgy farming and appallingly high levels of “by-catch” (accidentally caught fish that is generally thrown back in the sea to die) have left stocks in a parlous level. Apart from the loss of wildlife and damage to the marine environment, it compromises the ocean’s ability to act as a “carbon sink”, which is vital if we are to control global warming.
