Earth Overshoot Day is today, September 27th. Essentially, today, we have used up a years worth of the world's resource-generation capacity. Every day for the rest of the year takes us into deficit.
Or, stated differently, every year we are using 130%+ of the earths renewable resources. We deplete or exhaust resources in order to overconsume.
Video is interesting too.
