Today is a bad day for planet Earth. We’ve just reached Earth Overshoot Day, the date by which humanity has used up its yearly “allowance” of Earth’s natural resources – and it’s earlier than it has ever been before. Global Footprint Network (GFN) is the think tank behind Earth Overshoot Day. Each year, they work out the day in the year where humanity’s demand on nature exceeds what Earth can regenerate in that year. It’s all worked out with 15,000 data points per country from datasets from the United Nations and recent scientific literature.
