Earth Overshoot Day 2020 – the guessing game

Infographic showing the causes of humanity's global ecological footprint

Careful where you tread…

You heard it here first. Back in June 2013 I conducted a poll right here on Wibble, asking readers to guess when Earth Overshoot Day would happen. It looks like the folks at the Global Footprint Network have taken a leaf out of my own book: they’re inviting teachers and students to guess the date for 2020.

I’m just a trendsetter; I can’t help it.

About Earth Overshoot Day

Earth Overshoot Day marks the date when humanity’s demand for ecological resources and services in a given year exceeds what Earth can regenerate in that year. We maintain this deficit by liquidating stocks of ecological resources and accumulating waste, primarily carbon dioxide in the atmosphere. Earth Overshoot Day is hosted and calculated by Global Footprint Network, an international research organization that provides decision-makers with a menu of tools to help the human economy operate within Earth’s ecological limits.

To determine the date of Earth Overshoot Day for each year, Global Footprint Network calculates the number of days of that year that Earth’s biocapacity suffices to provide for humanity’s Ecological Footprint. The remainder of the year corresponds to global overshoot. Earth Overshoot Day is computed by dividing the planet’s biocapacity (the amount of ecological resources Earth is able to generate that year), by humanity’s Ecological Footprint (humanity’s demand for that year), and multiplying by 365, the number of days in a year:

(Earth’s Biocapacity / Humanity’s Ecological Footprint) x 365 = Earth Overshoot Day

  2. It’s a vicious cycle. Those of us who are not the biggest fans of the hustle and bustle move away to greener pastures. Soon enough, other people follow. And we turn it into what we ran away from. I blame it on developers. They’re greedy and nothing is holy for them.
