Think of it as everything man has built on Earth that's still standing. That includes the pyramids and everything older provided it's still around.
Now I'm going to throw out a number that's pretty hard to digest - thirty - trillion - tons. That's the estimated weight of the stuff we've built. Those pyramids, sure, but also the Trump Tower, all our roads and houses and bridges and airports, your car, your kid's bike, everything manmade.
But how is one to make sense of 30 trillion tons. This might help. 30 trillion tons represents 50 kilograms of stuff for each square metre of the Earth's surface.
Technosphere is a new term and according to the study published in journal The Anthropocene Review, it comprises of all the human-made structures including houses, factories and farms to airplanes, rockets, computer systems, tablets, smartphones and CDs, to the waste in landfills and spoil heaps that have been built to keep humans alive.
Humans have been having a huge impact on the planet through their activities and that’s where the Anthropocene concept has its roots in. It is an epoch that highlights the impact humans have made to the planet and it provides an understanding of how we have greatly changed the planet ever since our species started dominating.
Technosphere has its roots in the biosphere, but over the years it has gained so much of ‘weight’ and development that it has become a phenomenon of its own. Further, it is having a parasitic effect on the biosphere – like all human activities have on our planet.
Professor Mark Williams at the University of Leicester says “Compared with the biosphere, though, it is remarkably poor at recycling its own materials, as our burgeoning landfill sites show. This might be a barrier to its further success — or halt it altogether.”
According to Wiki, the average human body weight is just over 80 kilos which adds an extra 600-billion kilos of insatiable, voracious consumers all on its own. Maybe Elon Musk is right. Maybe we should get ourselves a new planet.
