Earth Overshoot Day (EOD) is the calculated illustrative calendar date on which humanity's resource consumption for the year exceeds Earth’s capacity to regenerate those resources that year. The term "overshoot" represents the level by which human population's demand overshoots the sustainable amount of biological resources regenerated on Earth. When viewed through an economic perspective, the annual EOD represents the day by which the planet's annual regenerative budget is spent, and humanity enters environmental deficit spending. EOD is calculated by dividing the world biocapacity (the amount of natural resources generated by Earth that year), by the world ecological footprint (humanity's consumption of Earth's natural resources for that year), and multiplying by 365 (366 in leap years), the number of days in a year: In 2020 the calculated overshoot day fell on August 22 (more than three weeks later than 2019) due to coronavirus induced lockdowns around the world. The president of the Global Footprint Network claims that the COVID-19 pandemic by itself is one of the manifestations of "ecological imbalance". Earth Overshoot Day is calculated by Global Footprint Network and is a campaign supported by dozens of other nonprofit organizations. Information about Global Footprint Network's calculations and national Ecological Footprints are available online. Background Andrew Simms of UK think tank New Economics Foundation originally developed the concept of Earth Overshoot Day. Global Footprint Network, a partner organization of New Economics Foundation, launches a campaign every year for EOD to raise awareness of Earth's limited resources. Global Footprint Network measures humanity's demand for and supply of natural resources and ecological services. Global Footprint Network estimates for 2022 that in less than seven months, humanity demanded more from nature than the planet's ecosystems can regenerate in the entire year. Human demand includes all demands that compete for the regenerative capacity of the planet's surface, such as renewable resources, CO2 sequestration, and urban space. According to Global Footprint Network, throughout most of history, humanity has used nature's resources to build cities and roads, to provide food and create products, and to release carbon dioxide at a rate that was well within Earth's budget. But by the early 1970s, that critical threshold had been crossed: Human consumption began outstripping what the planet could reproduce. According to their accounts, humanity's demand for resources is now equivalent to that of more than 1.7 Earths. The data shows us on track to require the resources of two planets
