In brief
Recent findings highlight an astonishing statistical fact: all human-made materials from the last century now outweigh Earth's total biomass.
In an epoch-defining snapshot of Earth’s ecological make-up, a comprehensive analysis completed in 2018 revealed a staggering statistic: the total weight of human-made materials—commonly referred to as “technostuff”—has now eclipsed the full weight of living organisms on our planet, which are estimated at 1.1 trillion tons. This impressive inventory was curated by Yinon M. Bar-On, a geophysicist at the California Institute of Technology, compiling data from an array of scientific studies and estimations.To put this into perspective, the sheer volume of items manufactured by humans in just 100 years—ranging from infrastructure such as roads and skyscrapers to everyday items like cellphones and paper towels—has literally outweighed everything in the biosphere, including the vast quantities of living things such as animals, plants, and microorganisms.Brice Ménard from Johns Hopkins University and Nikita Shtarkman, a talented computer scientist and graphic artist, have taken Dr. Bar-On’s findings and brought them to life through a compelling and vivid visualization that encapsulates this profoundly thought-provoking data. They previously collaborated on creating a digital map of the cosmos, which received over a million views online. Their latest project visualizes the distribution of living matter and human-made materials through a series of cubes, each size represented proportionally to their respective global weight.“I wanted to create a powerful visualization so everyone can see this with their own eyes,” Ménard stated in an email. The data representation aims to foster a greater awareness and appreciation of humanity's impact on the Earth throughout recent history, a stark reminder of our environmental footprint.
