Ecological Debt Day

Also known as Global Overshoot Day, this observance occurs when humanity’s annual demand for the goods and services that our land and seas can provide exceeds what Earth’s ecosystems can renew in a year. Overshoot means we are drawing down the planet’s principal rather than living off its annual interest. This overshoot leads to a depletion of Earth’s life-supporting natural capital and a buildup of carbon dioxide in the atmosphere. 

The population of the United States is using twice the renewable natural resources and services that can be regenerated within its borders. In 2015, it reached Debt Day on July 14. That's the day when a nation’s ecological footprint exceeds its biocapacity, and begins running an “ecological deficit.”
