Warning: This video is kind of intense, and may put you off sushi forever. Greenpeace has been trying to draw attention to cruel tuna fishing practices for a while, and now this anonymous helicopter pilot has footage of whales, rays, sharks, and dolphins being caught and slaughtered as collateral damage. Fish Aggregation Devices, which are intended to make tuna fishing more productive, also attract other marine animals which are then destroyed — plus, they kill young tuna, thus depleting the tuna stocks.
The helicopter pilot has what sounds like a New Zealand accent plus his voice is distorted for anonymity, which means you should turn on the subtitles … but really, it's the gruesome footage that makes the impact, and you could just turn the sound off entirely.
