And with an ever-accelerating tide of human impact, the oceans have changed more in the last thirty years than in all of human history before it.” Needless to say that change has been anything but beneficial. Indeed, it has been nothing short of devastating, and the carnage continues. “In most places, the oceans of have lost upwards of 75 percent of their megafauna – large animals such as whales, dolphins, sharks, rays and turtles – as fishing and hunting has spread in waves across the face of the planet.” For some species numbers are down by as much as 99 percent and there are dozens more that have literally disappeared.
