About 109 billion people have lived & died. Each grain of sand represents 10 million.

This stunning data visualization of human life by Max Roser was published in 2022.

Today there would be 805 green grains representing 8.05 billion people living on Earth. #science #art

I remember when the "conventional wisdom" was that there were as many people alive as had ever lived. Clearly not a data-driven conclusion. 🙄

@bosquebill I thought I had heard this in the last year or so too, so this surprised me as it’s quite a difference!

this is why I don't believe in ghosts. There would be way too much ghost noise evidence and chatter. It'd be really annoying.

And why would they stay on earth? I'm a ghost now? Send me to effing space! I'm gunna be a space ghost!

Oh, this is so good! I've always wondered about this, how many people have lived but the trouble is, what year, century, or millennia does h. sapiens become h. sapiens?

Fascinating. For some reason I imagined that the proportion of now living people would be even larger.

the long termers got it wrong. We should be optimizing for the happiness of the dead.

Each grain a unique collection of molecules and microbes, yet only a fraction of as many as stars in the Milky Way. Such a diverse world we inhabit.

Theory: if you flipped the hourglass upside down, you'd depict all the livestock animals currently alive versus all the ones that ever lived?

So at some point in the future, there'll be no more room for dead people, which will prevent people dying?

What's the definition of a person here? Ie how far back in time does the red portion represent. Obviously there's not a concrete time at which humans first appears. That said the exponential growth of pop size may make the precise cutoff not that important.

The accompanying article says that they’re only taking Homo sapiens into account, and beginning 200,000 years ago. But H. sapiens aren’t the only human species.

It's unclear whether an infographic like this is supposed to represent a 2D object or a 3D one. The ratio of areas is different from the ratio of volumes.
