Šta je teže: 1,1 bilion tona živog sveta na Zemlji ili 1,1 bilion tona veštačkih materijala?

Blog
Iako živi svet na Zemlji "drži liniju" na 1,1 bilion tona godinama unazad, težina materijala koji su ljudi proizveli eksponencijalno raste. Sve što smo ikada napravili i izgradili, od flaša preko zgrada od Lego kockica do mostova, otprilike ima jednak broj na vagi kao i sva biomasa. Poređenja radi, na početku dvadesetog veka, tvorevine ljudi težile su oko 35 milijardi tona, odnosno bile su čak 97 odsto lakše od živog sveta.
