Earth Overshoot Day
Earth Overshoot Day was August 2, the earliest Earth Overshoot Day ever. This is the day when humanity’s consumption of natural resources officially passes the planet’s ability to replenish then in one year.
If humanity lived sustainably on Earth, then Earth Overshoot Day would be at midnight December 31, meaning we would not have consumed more than the finite resources the planet provides for us. This is why the metaphor of Earth as a spaceship is the highest and best way to think about any aspect of climate change, sustainability, energy use and anything relative to the only place we have to live.
