When marine filmographer Dave Anderson’s drone took a tumble into cold seas, he didn’t think twice about diving in after it. It was a grave risk, mind you, given that he was all alone and miles from shore. But that said, he reckons the footage that the remote-controlled aircraft had captured was well worth the potential danger posed.
We are extremely lucky to have an ocean. So far, Earth is the only planet found to have one, at least in liquid form. And without our vast body of water, none of us would even be here. Not only did the first life evolve within it, but the seas also provide half of the oxygen we need.
