Frankly, I wouldn’t want either of these 2 scenarios; there has to be a middle for all of us.

“The USA has the largest per capita footprint in the world - a footprint of 9.57 hectares. If everyone on the planet was to live like the average American, we would need 5 planets to sustain everyone. At a footprint of 9.57 hectares per person, our planet’s biocapacity would only be able support about 1.2 billion people - far less than the 6 billion we have on Earth. On the other end of the spectrum, if everyone lived like those residing in Bangladesh, where the average footprint is only 0.5 hectares, then the earth could support roughly 22 billion people.”
