Overfishing - Revolution World Issue

An in-depth look at overfishing with world-renowned scientist Boris Worm, Ecology Action Centre's Mark Butler and WildAid's Peter Knights, narrated by Rob Stewart, Director of the film Revolution.

As a dominant predator in the oceans for over 450 million years, sharks control marine ecosystems by keeping other populations in check. Due to an increasing demand for shark fin soup, overfishing has caused a collapse in global shark populations by over ninety percent. Every year, between 70 and 100 million sharks are removed from the oceans. But it's not just shark populations that are in jeopardy. Fish are the main protein source for one third of the world's population, but as much as forty billion pounds of fish is discarded as bycatch at sea every year. As a result of global overfishing, pollution and ocean acidification, all large fish and mammal populations in the oceans have declined by up to ninety percent. If these trends continue, scientists and the UN predict that the world's fisheries will collapse by 2048.
