I’m currently reading a book by Kate Raworth called “Doughnut Economics.” In it, the author pleads for a rethink of the traditional growth model of an ever-expanding economy to one of equitable development, keeping planetary boundaries in mind, and ensuring redistribution of resources so that the most disadvantaged in society are also looked after.
In the traditional testosterone model (my own term) of economic growth, the rich prosper while the rest of the population benefit from the trickle-down effect of an expanding economy. Trickle down is a euphemism for the rich pissing down on the rest, thus validating the term piss-poor long after the expression came into use. I have examined the disastrous effects of testosterone based decision-making in two earlier blog posts: in 2015 (Golden Skirts vs. Testosterone in the Financial World), and in 2018 (Leadership Hope for a Warming World). Another reflective piece, published on this website in 2018, is related to the topic of the current post (Three Score Years and Ten: Planetary Health and your Lifetime).
It’s clear now to all but the most self-absorbed amongst us that we’re already consuming much more than the planet can sustainably provide. If Mother Nature and the earth’s resources were assumed to be a bank account, then we’re no longer living off the interest alone but are drawing down its capital. Since 1971, the Global Footprint Network has calculated Earth Overshoot Day for each year. In the website’s own words:
The Global Footprint Network calculates the number of days of the year that Earth’s bio-capacity suffices to provide for humanity’s ecological footprint. The remainder of the year corresponds to global consumption of Nature’s capital. Earth Overshoot Day is computed by dividing the planet’s bio-capacity (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:
(Planet’s Biocapacity / Humanity’s Ecological Footprint) x 365 = Earth Overshoot Day. (EOD)
In 2018, Earth Overshoot Day was calculated to have happened on 1 August. In 2004, the overshoot fell on 1 September! By this calculation, the last time mankind was truly sustainable was in 1969 or 1970 when overshoot day fell in a subsequent year!
Since this planetary over-consumption was first computed in 1971, we have been steadily increasing our ecological debt, and the interest we’re paying on that mounting debt is measured in food shortages, soil erosion, rising temperatures, increasing atmospheric CO2 concentration, biodiversity loss and much, much more. The problem is huge and solutions seem daunting and unreachable to us as individuals. Before we sink into despair, Kate Raworth tells us that there’s plenty we can do as societies to reverse this state of affairs and restore the planet to health. Doughnut Economics, the term she has coined, outlines the solutions that society needs. In the diagram above, the light green space denotes the resources mankind can safely take from the earth while restoring it to health. The dark green lines are the planetary boundaries that have to be respected if we wish to do this. The blue segments are the labels of the various sectors that have to be addressed. The book outlines broad prescriptions to deal with the problems of each of these sectors. In reading through this and other books written in a similar vein, we see that the answer to climate change lies in social change, not in new technologies. Technology alone is useless without the human will to adopt them and to adapt.
So here is the answer to the initial despairing question. What can we do as individuals? There’s plenty one can do. The EOD website lists hundreds of steps individuals can take to mitigate planetary health. Therein lies our power as individuals. Out of many, one.
