What's that? You've never celebrated Earth Overshoot Day? Well, it's not exactly a happy occasion.
It's the day when humans use more of Earth's natural resources in a calendar year than the planet can renew in a year.
In other words, it's the day humans completely drain Earth's natural-resource spending account and start dipping into savings again.
This year, it happened yesterday, the earliest mark in history, National Geographic reports.
It would take 1.6 Earths to support humans' resource consumption.
There are still 145 days left in the year. So if the Global Footprint Network's numbers are correct, this is a pretty significant dip into the planet's resource bank.
Here's an animated comic that breaks it down.
Here's another look at how much this means from the World Wildlife Fund.
