About 7.5 billion people share the earth with us right now. That’s around twice the number that was here in 1970, only 47 years ago. Roughly every 13 years since 1960, about a billion more people have come onboard, and this pattern continues. Our first billion didn’t arrive until 1804, after Homo Sapiens existed for 75,000 years or so.
