How is Earth Overshoot day arrived at?
The Earth Overshoot Day is arrived at by dividing the world bio-capacity (the amount of natural resources generated by Earth in that particular year), by the world ecological footprint (humanity’s consumption of Earth’s natural resources for that particular year), and multiplying the result by 365 (the number of days in one Gregorian common calendar year).
Earth Overshoot Day = (World Bio-capacity/ World Ecological Footprint) * 365
