[im] Global human-made mass exceeds all living biomass

[János Sugár]

Humanity has become a dominant force in shaping 
the face of Earth. An emerging question is how 
the overall material output of human activities 
compares to the overall natural biomass. Here we 
quantify the human-made mass, and compare it to 
the overall living biomass on Earth, which 
currently equals approximately 1.1 teratonnes. We 
find that Earth is exactly at the crossover 
point; in the year 2020 (± 6), the human-made 
mass, which has recently doubled roughly every 20 
years, will surpass all global living biomass.
