How many Earths? How many countries?

Humanity is using nature 1.7 times faster than our planet’s biocapacity can regenerate. That’s equivalent to using the resources of 1.7 Earths. How many Earths would we need if everyone on the planet lived like the residents of your country? Here’s how we calculate that, using the United States as an example:

The Ecological Footprint for the United States is 8.1 gha per person (in 2017) and global biocapacity is 1.6 gha per person (in 2017). Therefore, we would need (8.1/ 1.6) = 5.0 Earths if everyone lived like Americans.

Here’s another interesting way to look at the data. How many Japans does Japan need to meet its residents’ demand on nature?

The Ecological Footprint for Japan is 4.7 gha per person (in 2017) and Japan’s biocapacity is 0.6 gha per person (in 2017). Therefore, it would take (4.7/ 0.6) = 7.8 Japans to meet its residents’ demand on nature.
