By mid-summer of each year, we use up the Earth.

Known as Earth Overshoot Day, it’s the day, sometime in August, when our yearly demand for ecological resources exceeds how much the planet can replenish those resources for the year. Soon after August 15, this year, Earth will be operating on a deficit.

All the while, the population of Earth is growing. It’s estimated there will be 9 billion people by 2050, an additional 2 billion than now.
