The Spider-to-Human Ratio

spider to human ratio

Since I like spiders, I was pleased to read a rough estimate of 21 quadrillion for the world’s population of spiders (source: here).

The website http://www.worldometers.info/world-population/ gives the current human population as ~7.4 billion. Dividing the estimated spider population by the estimated human population yields Earth’s estimated spider-to-human ratio: 2.8 million.

Yes, your share approaches three million spiders. At least they are good at taking care of themselves!
