Loading ...The ocean just one problem of many and keep in mind it provides more than half the air you breath.
Thirty-one animal and fish species have been declared extinct and more than 300 species of sharks and rays are now threatened with extinction, according to the International Union for Conservation of Nature, which published a report Thursday.
Among those at risk are four hammerhead shark species, four species of angel shark and the giant manta ray.
