The Anthropocene Review is a journal that looks at the current epoch of the Earth’s history, the one in which humans have so impacted the planet as to mark it as unique from previous epochs. Although the Anthropocene concept is still rather new, it is gaining recognition, and as a byproduct comes a new term: the technosphere.
The technosphere can be compared to the biosphere, which is the system by which life on the planet interacts. The technosphere, in contrast, consists of all the stuff that humans have made: houses, airports, mines, smartphones, AOL free trial CDs, and all the garbage in landfills across the world.
While that may be an interesting concept in and of itself, it’s helpful in putting into context just how much stuff humans have made. Currently, estimates of the total weight of the technosphere come to about 30 million (metric) tons. That works out to about 50 kilos of stuff per square meter of the Earth’s surface.
That’s a lot of stuff.
The technosphere has been evolving for millennia now, but has taken on a life of its own in recent centuries. Frankly, it’s not all the good at being a thing. Where as the biosphere is incredibly efficient, with each living organism providing nutrients for other organisms at some point in its life or death, the technosphere is terrible at recycling, which is why it weighs so much. There’s no getting rid of a lot of this stuff.
The concept of the technosphere, and how terrifyingly huge it is, helps to put into context just how important it is that we get better at efficiently using the resources to which we have access. Eventually, we’re going to run out of raw materials with which to make more things, and at that point the technosphere will have crushed everything else under its weight.
