I recently completed a college module on economics. A guest lecturer – very familiar to us in the agri industry – was drafted in for a slot on environmental economics. And it was on this lecture that I learned about the “tragedy of the commons”. This is a problem that occurs when individuals neglect the wellbeing of society in the pursuit of personal gain. The concept originated when British economist William Forster Lloyd used the example of the effects of unregulated grazing on “common” land.
