Entering a new era... literally

From National Geographic News:
Earth's climate and biodiversity aren't the only things being dramatically affected by humans - the world's soils are also shifting beneath our feet, a new report says.

"Global soil change" due to human activities is a major component of what some experts say should be recognized as a new period of geologic time: the Anthropocene, or human-made, age.

This new era will be defined by the pervasiveness of human environmental impacts, including changes to Earth's soils and surface geology, proponents of the theory say.
It's says a lot about how deep our impact of the earth runs when we create a new geological era just by living.
