Humanity has become a dominant force in shaping the face of Earth 1 – 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 teratonnes 10 , 11 . We find that Earth is exactly at the crossover point; in the year 2020 (± 6), the anthropogenic mass, which has… Expand

The Anthropocene by the Numbers: A Quantitative Snapshot of Humanity's Influence on the Planet
The presence and action of humans on Earth has exerted a strong influence on the evolution of the planet over the past ≈ 10,000 years, the consequences of which are now becoming broadly evident.Expand
Our future in the Anthropocene biosphere
TLDR
This article provides a systemic overview of the current situation where people and nature are dynamically intertwined and embedded in the biosphere, placing shocks and extreme events as part of this dynamic. Expand
Triggering a Climate Change Dominated “Anthropocene”: Is It Common among Exocivilizations?
We seek to model the coupled evolution of a civilization and its host planet through the era when energy harvesting by the civilization drives the planet into new and adverse climate states. In thisExpand
Sustainability of the global sand system in the Anthropocene
Summary Sand, gravel, and crushed rock, together referred to as construction aggregates, are the most extracted solid materials. Growing demand is damaging ecosystems, triggering social conflicts,Expand
Exemplary Ethical Communities. A New Concept for a Livable Anthropocene
This article argues that we need to look at living examples provided by non-state communities in various regions of the world that are, perhaps unwittingly, contributing to the maintenance of theExpand
Modern cities modelled as “super‐cells” rather than multicellular organisms: Implications for industry, goods and services

TLDR
A “super‐cell” industrialized city model is developed with a “eukarcity” with citynucleus (urban area) as a regulating centre, and organaras (enclosed systems, which provide the majority of goods and services) as the functional components, and cityplasm (natural ecosystems and farmlands) asThe matrix may improve the vitality and sustainability of cities through planning and management.

The role of planetary boundaries in assessing absolute environmental sustainability across scales.
TLDR
It is argued that PBs must be linked to human consumption as the main socio-economic driver and that planetary concerns can only be addressed through a holistic perspective that encompasses global tele-connections. Expand
Evolution beyond nature's laws
To understand the upper limits or potentials of metabolism, the theory of evolution needs to be defined from the mathematical and physical points of view. In this study, we proposed that life is aExpand
The important role of strong sustainability and the potential of the circular economy in generating a socially and ecologically just future
The human-nature relationship is in a state of deep imbalance, where no country in the world currently meets the needs of its citizens at a scale that remains within planetary boundaries. Covid-19Expand
The Loss of Diversity in the Anthropocene Biological and Cultural Dimensions

Quantifying and mapping the human appropriation of net primary production in earth's terrestrial ecosystems
TLDR
A comprehensive assessment of global HANPP based on vegetation modeling, agricultural and forestry statistics, and geographical information systems data on land use, land cover, and soil degradation that localizes human impact on ecosystems suggests large-scale schemes to substitute biomass for fossil fuels should be viewed cautiously.

TLDR
This work uses atmospheric carbon dioxide concentration as a single, simple indicator to track the progression of the Anthropocene, the current epoch in which humans and the authors' societies have become a global geophysical force. Expand

The figures reflect the current patterns of exploitation distribution and consumption of a much larger population; there must be limits to growth. Expand
The biomass distribution on Earth
TLDR
The overall biomass composition of the biosphere is assembled, establishing a census of the ≈550 gigatons of carbon (Gt C) of biomass distributed among all of the kingdoms of life and shows that terrestrial biomass is about two orders of magnitude higher than marine biomass and estimate a total of ≈6 Gt C of marine biota, doubling the previous estimated quantity.

Archaeological assessment reveals Earth’s early transformation through land use
TLDR
An empirical global assessment of land use from 10,000 years before the present (yr B.P.) to 1850 CE reveals a planet largely transformed by hunter-gatherers, farmers, and pastoralists by 3000 years ago, considerably earlier than the dates in the land-use reconstructions commonly used by Earth scientists.
