Earth Overshoot Day is the day when—according to estimates—the total combined consumption of all human activity on Earth in a year overtakes the planet's ability to generate those resources for that year.
How is it measured ? "It's quite simple," says Dr. Mathis Wackernagel of the think tank Global Footprint Network. "We look at all the resource demands of humanity that compete for space, like food, fiber, timber, et cetera, then we look at how much area is needed to provide those services and how much productive surface is available."
Here's his bottom line metaphor. Earth Overshoot Day is like the day you spend more than your salary for a year, only you are all humans and your salary is Earth's biocapacity. Ideally, Overshoot Day would come after December 31. It wasn't too far off in 1970, when it occurred on December 23. But Overshoot Day creep has kicked in ever since. August 13 is the earliest yet—four days ahead of last year's previous record.

I have this same problem when I play RTS games where I have to gather resources.
Sooner or later I chop down all the trees, catch all the fish, and mine everything.

That's why you need to build farms and send trade units to the nearest market.
