Extreme makeover: are humans reshaping Earth? http://apocadocs.com/s.pl?1305591242
If alien geologists were to visit our planet 10 million years from now, would they discern a distinct human fingerprint in Earth's accumulating layers of rock and sediment?
Will homo sapiens, in other words, define a geological period in the way dinosaurs -- and their vanishing act -- helped mark the Jurassic and the Cretaceous?
A growing number of scientists, some gathered at a one-day symposium this week at the British Geological Society in London, say "yes"... For the first time in Earth's 4.7 billion year history, a single species has not only radically changed Earth's morphology, chemistry and biology, it is now aware of having done so.
