World Overshoot Day This is the day on which our total Ecological Footprint is equal to the bio-capacity that nature can regenerate in that year. As humanity’s consumption of resources increases, World Overshoot Day creeps ever earlier on the calendar It is calculated by calculating the ratio of global available biocapacity (supply) to global Ecological Footprint (demand) multiplied by 365.
