Sharks in Trouble

This year has seen major shark conservation actions taken around the world, but more action is needed by many more countries. This video, a companion to a report by the Pew Environment Group, illustrates how these animals are threatened by commercial fisheries throughout the world's oceans. It points out that, according to global reports, shark populations have declined by as much as 70 to 80 percent. Scientists estimate that 30 percent of all shark species are threatened or near-threatened with extinction.
