Nothing to celebrate, actually. Today is estimated to be the day on which mankind has consumed the entire stocks of renewable resources our planet will generate this year. Today is Earth Overshoot Day.
The best image I can come up with for our predicament is that of a guy who has just run headfirst into a wall. The guy shakes off the impact, backs up and runs headlong into the wall again - and again, and again, and again. He just keeps doing it until he kills himself.
Overshoot is such an existential problem that it never so much as crosses the lips of any of our political leaders - any of them. Overshoot is one of those things they don't dare talk about because, like many other problems, it reveals that our society is based on models - economic, industrial, social, political - that have outlived their utility and turned dysfunctional. Overshoot is us turning on ourselves and nothing less.
