If everyone on the planet consumed as much as the average US citizen, four Earths would be needed to sustain them⁠⁠{Weekend Repost}⁠A set of data produced by the Global Footprint Network measures the ecological impact of the populations of different countries. Their footprint is calculated using statistics about the natural resources used to make the products they consume, as well as their carbon emissions. The researchers calculated the amount of land and sea necessary to sustain each country. The whole world needs 1.5 Earths to be sustainable the way we consume now, and if the entire humanity were to consume the way the United States does, we would need 3.9 Earths. Yet it isn’t the worst, as it is topped by Kuwait (5.1 Earths), Australia (4.8 Earths), the United Arab Emirates (4.7 Earths), and Qatar (4.0 Earths).
