2 August 2017
Today, 2nd August, marks Earth Overshoot Day 2017 - the day by which, this year, the human race will have used more of Earth's natural resources than the planet can renew in the whole year.
Humans / Us use more ecological resources and services than nature can regenerate and this puts the Earth on an unsustainable trajectory.
Through overfishing, overharvesting forests, and emitting more carbon dioxide into the atmosphere than forests can cope with, humans are still demanding more from the earth than it can produce.
Every natural resource that we use from this day - 2 August - onwards is in effect unsustainable in the long term. Over the course of a year nowadays we use 170 per cent of the world's natural output.
Planet Earth -- Humans live here and it is, currently, the only known habitable planet
(Yes I know you know this but it is worth pointing out)
Earth Overshoot Day comes earlier and earlier each passing year now. A decade ago we used just 144 per cent of the Earth's biocapacity which is double the 78 per cent that was used in 1963. I was born in 1965 so for virtually all my life humans have over-consumed and polluted in excess of our planets ability.
Currently, carbon emissions make up 60 per cent of humanity’s Ecological Footprint. If carbon emissions were cut in half, the date of Earth Overshoot Day would be pushed back by 89 days, or about three months.
The Global Footprint Network has also produced a calculator that allows you to track what impact your own actions have on the world's natural resources at www.footprintcalculator.org.
