Summary:
Humans have dramatically changed Earths surface. Satellite images show New York Citys sparkling lights at night and the Great Wall of China during the day. But we have also produced signatures in the strata beneath our feat that cant be seen so readily, like the plastic that litters the ocean floor and a strong radiation signal produced by atomic bomb tests. For many scientists, this kind of evidence is enough to formally declare a new geologic epochone that will be visible in the layers of sediment millions of years from now. And new research, published March 1 in American Mineralogist, adds another layer to the argument for the so-called Anthropocene: man-made minerals.
