" As soon as you stop thinking about it, the deep can so easily vanish out of mind — more so than that other great distant realm, outer space. The deep has no stars at night to remind us it is there, and no moon shining down. And yet, this hidden place reaches into our daily lives and makes vital things happen without our knowing. The deep, quite simply makes this planet habitable. "
