When teaching permaculture I often start out by doing a giant problems mind map. I ask students to brainstorm all of the major problems they see in the world to reflect on what brought them to study permaculture. Nine times out of ten the idea of overpopulation as a root problem in the world comes up.
Overpopulation describes a situation where there are too many people for the amount of resources available. It puts the blame of the environmental crisis on the sheer number of people on the planet.
Natural scientist and former senior manager of the BBC David Attenborough sums up this sentiment when he said, We are a plague on the Earth. Either we limit our population growth or the natural world will do it for us[.]
This cultural narrative, that human beings are the root cause of the environmental cri-sis is everywhere, especially among environmentalists. We also see this belief within permaculture design. The third ethic of permaculture reads:
Setting limits to population and consumption: By governing our own needs we can set resources aside to the above principles.
Not only is this idea of overpopulation oversimplified and inaccurate, it upholds a de-generative paradigm of scarcity, fear and competition that goes against the core teachings of permaculture. It also perpetuates problematic thinking that leads to ineffective and unjust public policies and global solutions. As permaculturalists, it is important that we contradict this notion that simply more people on the planet equals less resources and more pollution. We need to engage in dialog around the true roots of environmental, social and economic degradation. In this way, we can begin to shift mental models and design more effective and just solutions that take into account the real root causes of degradation and injustice.
In his book
Permaculture: Principles and Pathways Beyond Sustainability, David Holmgren reframed the third ethic as fair share or redistribute the surplus. He points out the paradox of permacultures core belief of abundance and this ethic. He states that, Except in extreme famine and other natural disasters, scarcity is a culturally mediated reality; it is largely created by industrial economics and power, rather than actual physical limits to growth...
