Is Planet Earth Under New Management? : Krulwich Wonders… : NPR

A hundred million years from now, when we’re all dead and gone, a team of geologists will be digging in a field somewhere …and they will discover, buried in the rocks below, a thin layer of sediment — very thin, about the width of a cigarette paper, says British stratigrapher Jan Zalasiewicz. That skinny strip, when they look close, will send what’s called a “biostratigraphic signal” that something enormous happened back in our era, something life-changing, planet-reorganizing, even Earth-shaping. The evidence, when they look closely, will be visible in that same skinny layer all over the world. In her new bookThe Sixth Extinction, Elizabeth Kolbert describes what they’ll find.

This particular pattern of hydrogen, oxygen, carbon, and other associated elements, found this article interesting.  We are bags of water and carbon, going from being 75% water at birth, to around 50% in our elder years.
