全球人造物质超过了所有生物总量
2020-12-12 20:11

以色列魏茨曼科学研究所的Ron Milo团队发现,全球人造物质超过了所有生物总量。相关论文于2020年12月9日在线发表在《自然》杂志上。

研究人员对被称为“人为质量”的人造质量进行了量化,并将其与地球上目前的总生物量(约等于1.1兆吨)进行了比较。研究人员发现地球正好位于交叉点; 到2020年(±6年),人为质量(最近每20年增加一倍)将超过全球所有生物量。平均而言,全球每个人每周产生的人为质量等于或超过其体重。对人类事业的这种量化给出了人类世的定量和象征性表征。

据悉,人类已经成为塑造地球的主要力量。一个新出现的问题是人类活动的整体物质输出与整体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.
