Put otherwise, based on my calculations, if the whole world came to look like one of our most successful ecovillages, we would still need one and a half planet’s worth of Earth’s biocapacity. Dwell on that for a moment.
I do not share this conclusion to provoke despair, although I admit that it conveys the magnitude of our ecological predicament with disarming clarity. Nor do I share this to criticise the noble and necessary efforts of the ecovillage movement, which clearly is doing far more than most to push the frontiers of environmental practice.
Rather, I share this in the hope of shaking the environmental movement, and the broader public, awake. With our eyes open, let us begin by acknowledging that tinkering around the edges of consumer capitalism is utterly inadequate.
In a full world of seven billion people and counting, a “fair share” ecological footprint means reducing our impacts to a small fraction of what they are today. Such fundamental change to our ways of living is incompatible with a growth-oriented civilisation.
Some people may find this this position too “radical” to digest, but I would argue that this position is merely shaped by an honest review of the evidence.
Too radical? Nope. Still not radical enough. Still not quite willing to face the cold, hard reality, still softening the edges, still behind the curve.Unpopular though it is to say, we must also have fewer children, or else our species will grow itself into a catastrophe.
Here's the truth: having fewer children still isn't enough. If the whole world is already in overshoot to the tune of 1.5 Earths, and if we presume that all the people currently alive of child-producing age who haven't already had children have just one child, we'd still be looking at 10+ billion humans before the population stops growing.
There is only one possible outcome and that is declines in human population numbers due to an increased death rate resulting from drought, famine, war and disease. That is what is going to happen, and that is what we need to prepare for.
Nice try though.
