Earth Technosphere Weighs 30 Trillion Tons

An international team led by University of Leicester geologists has made the first estimate of the sheer size of the physical structure of the planet’s technosphere – suggesting that its mass approximates to an enormous 30 trillion tonnes.

The technosphere is comprised of all structures that humans have constructed to keep them alive on the planet — from houses, factories and farms to computer systems, smartphones and CDs, to the waste in landfills and spoil heaps.

In a new paper published in the journal The Anthropocene Review, the team suggests that it represents a mass of more than 50 kilos for every square metre of Earth’s surface.
