Earth Overshoot Day is a day intended to remind people of the impact of a modern life-style on the planet. It marks the point in each Gregorian calendar year where human consumption of natural resources exceeds the earth’s ability to replace those resources that year. At a sustainable rate of consumption, Earth Overshoot Day would fall at the end of each calendar year.
Calculating all the resources available on earth, and the actual resources used, is, of course, an inexact science, so the precise placement of this Day should be taken with a pinch of salt. However, it serves as a useful reminder that humans are living beyond their means.
The Day, also known as Earth Overshoot Day, is a good time to hold conservation campaigns, implement and advertise more eco-friendly ways of life, and generally work towards sustainable living. Celebrate by finding a local environmental issue and getting your community to rally behind it.
