Read MoreNew Executive Order Threatens Decades of Shark and Ocean Protection in USA Waters
A new directive from the White House threatens to undo decades of hard-won marine conservation in the name of deregulation. President Trump’s recently signed Executive Order, titled “Restoring American Saltwater Angling and Recreation,” takes direct aim at the federal fisheries management systems that protect important marine habitat and our most vulnerable marine species, including sharks.
