New genetic findings suggest that early humans living about one million years ago were extremely close to extinction. The genetic evidence suggests that the effective population—an indicator of genetic diversity—of early human species back then, including Homo erectus, H.

However, if people only consumed what they actually needed, then the Earth could potentially support a much higher figure. But we need to consider not just quantity but also quality—Earth might be able to theoretically support over one trillion people, but what would their quality of life be like?
