Will banning trade in fins help endangered sharks? Experts are divided

The Shark Fin Sales Elimination Act of 2017, introduced before Congress on March 9, would terminate the possession and trade of shark fins in all 50 U.S. states and 16 territories. Activists and advocacy groups often cheer these bans as a way to protect sharks. Internationally about 70 of the planet’s 400-plus shark species now face extinction, often due to overfishing. However, some experts argue that better tracking to determine whether imported fins were caught sustainably, followed by trade restrictions on those that weren’t, represent the best steps toward saving threatened shark species. Some go so far as to argue that a U.S. trade ban may do more harm than good, by crushing a domestic industry that exports sustainably caught fins to markets in Asia and allowing less-sustainable fisheries to take up the slack. click here to read the story 08:54
