The costs of global ecological overspending are becoming increasingly evident around the world, in the form of deforestation, drought, fresh-water scarcity, soil erosion, biodiversity loss, and the buildup of carbon dioxide in the atmosphere. But the trend can be reversed, if we moved Earth Overshoot Day back 4.5 days every year, we would return to using the resources of one planet by 2050. Global Footprint Network’s research team is able to work by calculating the number of days by which Earth Overshoot Day would move if the solutions they identified were implemented.
