Earth Overshoot Day, is the date when humanity’s demand for ecological resources and services in a given year exceeds what the Earth can regenerate in that year.
Australia’s Overshoot Day is March 22nd, the date on which Earth Overshoot Day would fall if all of humanity consumed like Australia's population does. If everyone lived like Australia we would need 4.5 planets.
Australia consumes beyond the capacity of the Earth, our home, to sustain us.
