How we can protect the vast living space of the deep ocean. The ocean is under grave threat and, unless action is taken, it will be too late to reverse the serious damage that humans are inflicting. Marine biologist Helen Scales argues that instead of letting waves of exploitation sweep through the deep ocean, we should choose to protect this vast living realm. "Instead of letting these waves of exploitation sweep through the deep, humanity could decide to protect this vast living realm. Agreements could be drawn up that declare the deep ocean off limits to extractive and exploitative industries. Such a move would halt existing damaging activities before they cause any more trouble, and prevent the newest threats from taking hold. And there are clear, logical motivations for doing so."
