以色列魏茨曼科學研究所的Ron Milo團隊發現,全球人造物質超過了所有生物總量。相關論文於2020年12月9日在線發表在《自然》雜誌上。
研究人員對被稱為「人為質量」的人造質量進行了量化,並將其與地球上目前的總生物量(約等於1.1兆噸)進行了比較。研究人員發現地球正好位於交叉點; 到2020年(±6年),人為質量(最近每20年增加一倍)將超過全球所有生物量。平均而言,全球每個人每周產生的人為質量等於或超過其體重。對人類事業的這種量化給出了人類世的定量和象徵性表徵。
據悉,人類已經成為塑造地球的主要力量。一個新出現的問題是人類活動的整體物質輸出與整體自然生物量相比如何。

Abstract: Humanity has become a dominant force in shaping the face of Earth1,2,3,4,5,6,7,8,9. 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, referred to as 『anthropogenic mass』, and compare it to the overall living biomass on Earth, which currently equals approximately 1.1 teratonnes10,11. We find that Earth is exactly at the crossover point; in the year 2020 (± 6), the anthropogenic mass, which has recently doubled roughly every 20 years, will surpass all global living biomass. On average, for each person on the globe, anthropogenic mass equal to more than his or her bodyweight is produced every week.
