What does “dolphin-safe tuna” mean, and how can I make sure that the tuna I buy is “dolphin-safe”?
Biologists estimate that, since the beginning of large-scale commercial fishing in the late 1950s, more than 10 million dolphins have been drowned when inadvertently snared in the huge underwater driftnets meant to catch tuna and other fish. Driftnets, which can extend 50 miles as they are left to drag overnight, are indiscriminate killing tools often referred to as “walls of death.”
