Sharks have a long and impressive lineage. Ancient sharks were cruising the ocean 400 million year ago- long before dinosaurs roamed on land. Relatives of the great white like the giant megatooth evolved more than 20 million years ago. But today, sharks are threatened from a different predator.
Every year, humans kill an estimated 70 million sharks. The threats we pose are many. By-catch: the accidental killing of sharks in fishing gear intended for other species. Illegal poaching and hunting: selling shark fins for soup and sportfishing for shark-jaw trophies. Nets: placed along coastlines to keep sharks away from beaches. It turns out that sharks have more reason to fear humans than the other way around.
So, what poses a greater threat to humans--sharks or toasters? The creators of this public service announcement try to put the human fear of shark attacks in perspective.
