I was reflecting this morning on the ‘growth-collapse’ paradigm of human behaviour I wrote about recently. It’s hard to understand why we have developed such a transfixion on the concept of endless growth, when history (and present circumstances) suggest that it doesn’t serve us so well.


It seems somewhat maladaptive that by and large we are unable to within our environmental limits. Past civilizations (with a few notable exceptions) expand until they go beyond their limits, and consequently collapse. A much more adaptive response would surely be to live in equilibrium with the environment.


This is what has me fascinated with some of the indigenous peoples around the globe. Take the Australian aboriginals, for whom the land and environment is not something to be consumed and exhausted, but rather a gift to be thankful for. They view themselves as custodians and protectors of their environment, rather than consumers of it. Whether it is due to genes or other factors, they have developed a certain equilibrium with their surrounds that has allowed them to survive for 60,000 years whilst countless great civilizations around the world have risen and fallen. For me, this makes them a wiser and more emotionally evolved culture than the modern industrialized culture. But cultures like that of the Aboriginals are the exception, rather than the rule. Some island cultures (like Tikopia and Tonga) have come close to a clash with environmental limitations, and responded by implementing measures of population control and more sustainable agricultural techniques that have enabled them to live in equilibrium with their environment. Imagine, instead of dedicating excess resources towards growth, those resources could instead be diverted towards prosperity and wellbeing.


Whether this constant drive for growth is a uniquely human trait is uncertain. It is possible that other species would grow and grow if they were not subject to normal population limiting factors such as predators and disease. In fact, there are examples in which this has happened. When European settlers moved to Australia, they introduced a number of foreign species to make the environment more familiar. This proved an incredibly naïve and devastating error of judgement.


Australia’s ecosystem is quite unlike many of the others in the world (it has a startlingly high percentage of species unique to the continent – link http://www.dfat.gov.au/facts/flora_and_fauna.html) and is delicately balanced. When European rabbits were introduced to the country it was a disaster. They had no natural predators in Australia, and were not controlled by natural disease. And after all, rabbits do mate like…


Rabbit population growth boomed uncontrollably and aspects of the environment were damaged beyond repair. I recall from reading Bryson’s book Down Under, that much of the delicate inland vegetation was lost forever to the hungry stomachs of unstoppable rabbits. It was only human intervention through scientifically designed diseases that brought the population back under some sort of control.


Perhaps it is simply that this drive for species growth is inherent within all species, but it is the mastery humans have developed over their environment and other species that has enabled them to overcome population limiting factors. Our science and technology means that we are not under threat from predators, and we have been able to eradicate an extraordinary number of lethal diseases.


There’s also the point that our brains have evolved to be hardwired to tackling immediate, short-term problems that we are faced with. We are not so tuned in to complex, longer-term challenges. I’d suggest that the challenges presented by growth, unsustainable living and bumping in to limitations build up over time and until we reach tipping points, they fall in to the category of long-term challenges. Past societies only have typically only responded when lack of sustainability becomes an immediate problem (usually food shortages). So in a sense, our mastery of the environment means that we now bump in to problems that we haven’t evolved to know how to tackle – the limitations of our environment.


Only, this would be the first time we bump in to global limitations, rather than local limitations like past civilizations have done. What the consequences of this would be, we really have no idea. This is a unique period in human history.


The challenges may seem scary, but it’s a very exciting time to be around.
