Sadly, this is a yearly event; hence the copy and paste and edit from last year.
Earth Overshoot Day is when;
“We use more ecological resources and services than nature can regenerate through overfishing, overharvesting forests, and emitting more carbon dioxide into the atmosphere than forests can sequester.”
Ideally, Earth Overshoot Day would never occur, with each year our civilization extracting less than the planet can produce. At a perfect sustainable balance, Earth Overshoot Day would be midnight, New Year’s Eve. In 2018, Earth Overshoot Day is August 1. That’s using 365 days of planetary productivity in 212 days… Just like with financial systems, such a deficit is unsustainable.
August 1 is the Earth Overshoot Day for the planet. For the United States, the day is March 15, not even as late as tax day. The last time we matched the planet’s resources was 1970. One bit of good news, while the day may be creeping through the calendar in the wrong direction, the pace has flattened dramatically in the last ten years.
