Fig. 2.

It is the same graph as Fig. 1, but expressed per person. It shows human demand on nature (humanity's Ecological Footprint per resident) compared to how much Earth's ecosystems can renew (the planet's biocapacity per person) for the last six decades. The results here are expressed not in “number of Earths” as in Fig. 1, but in global hectares, or biologically productive hectares with world average productivity. Explanations on the unit of measurement and the underlying logic is summarized in section 2 of Wackernagel et al.‘s open access paper (2019). The graph indicates that the growing human population has led to less biocapacity per person, while demand per Earth resident has stayed relatively similar. Consumption of products may have gone up, but with increases in efficiency the resulting demand on nature per person has not (data source: data.footprintnetwork.org).
