Since the release of Jaws in 1975, we've been wading into the water a bit more tentatively. But it is the sharks that need to worry. They've been around for almost half a billion years, but they could go extinct on the West Coast in the coming decades.
Great whites have survived for millions of years, surviving mass extinctions and rightfully earning their top spot as apex ocean predators. But unless we increase protections for them, they may not survive much longer.
We all know sharks live in the ocean, but we don't expect to see one. And yet an image in our minds causes us to fear that a shark might be checking us out. Sometimes that feeling is true. Or was it only seaweed?
