The technosphere

Some pundits suggest that we are living through the Anthropocene, a geological epoch during which humanity is creating a layer of material and having a global geographic impact on the planet that will be seen by pundits of the far distant future as akin to natural epochs in which boundary layers are formed. Now, researchers at the University of Leicester have estimated just how much stuff - whether buildings, roads, trains, solar panels, oil pumps, cars, smart phones, plastic bags and everything else we have fabricated - we have on planet Earth. It amounts to some 30 trillion tons of material including all the waste and landfill. This is a troubling thought for many given the unsustainability of our endeavors and limited resources.
