British Virgin Islands to become shark sanctuary
A shark sanctuary is to be created in the territorial waters of the British Virgin Island[s], its government has announced. The waters cover an approximate 31,000 square miles and it is hoped that the sanctuary will help protect all shark species. Shark numbers have been dwindling and in January the IUCN announced that a quarter of the world’s sharks and rays are threatened with extinction.
Kedrick Pickering, deputy premier and minister for natural resources, said that the loss of sharks disrupts the predator-prey balance, compromising the health of oceans and reefs and the survival of other marine creatures.
“The best way to manage their populations is to let them fulfill their ecological role as apex predators,” Pickering said at a conference in Belgium.
