👉 Ecological footprint. The ecological footprint is a measure of human demand on the Earth's ecosystems . It compares human demand with planet Earth 's ecological capacity to regenerate.
👉 If everyone lived like you, we would need 4 planet Earth's just to support us.
👉 It has been suggested that if everyone on the planet consumed as much as the average US citizen, four Earths would be needed to sustain them. But where does this claim originate, and how is it calculated? The world's seven billion people consume varying amounts of the planet's resources.
👉 The Ecological Footprint for the United States is 8.1 gha per person (in 2018) and global biocapacity is 1.6 gha per person (in 2018). Therefore, we would need (8.1/ 1.6) = 5.1 Earths if everyone lived like Americans. Here's another interesting way to look at the data.
👉 As the world's human population grows unsustainably, so do its unyielding demands for water, land, trees and fossil fuels — all of which come at a steep price for other life forms already being forced into remote corners, deprived of food sources or outcompeted by introduced species.
👉 What exactly are we consuming? The global footprint measures human demand on nature. To illustrate, we extract 88 billion tons of natural resources from Earth every year (In 2017). This is a lot.
