Earth Day perspectives

Some interesting links and information about water – which looks abundant on the surface of things (like earth) but isn’t as huge a portion of the earth as we think. I often wonder if this is because of the way that we imagine the oceans themselves – as though it is oceans-all-the-way-down. I think the idea of “the depths of the ocean” or “the deep” in general might play into that way of imagining them as vast, mysterious and fortified from the negative effects of human activity.
