Surge in global metal mining threatens vulnerable ecosystems
In Fig. 3, we show all mining activities projected into 1 × 1 degree cells. 3 Among the mining cells, we observe strong heterogeneity regarding extraction volumes and a highly skewed distribution, i.e. a small fraction of mining areas reporting very large extraction volumes and vice versa. For 2019, about 95% of all mining areas indicate less ...
