As the world’s ranks swell, population shifts have emerged as a major global challenge with potentially catastrophic implications. Endless debates over immigration rights have failed to produce the faintest hint of an acceptable solution. So perhaps an alternative approach would be to factor in an underlying basic law of chemistry. At the risk of gross oversimplification, what if we saw the flow of populations as the human equivalent of osmosis?

In high-school chemistry we learned that, in a container of water divided into two halves by a semipermeable membrane, uneven concentrations of salt resulted in movement of water from the more dilute side to the side of greater concentration. The greater the discrepancy in solute concentration, be it a salt molecule or a complex plasma protein, the greater the force to equalise the concentrations.

Now imagine the world as a giant vat subdivided into a number of smaller containers (nations) separated from each other by semipermeable membranes (borders). Instead of salt, provide each container with differing amounts of food, shelter and essential services. In this scenario, population flow from nation to nation will be a direct function of the degree of difference of goods, opportunities and hope.

This shift of populations isn’t just an ethical or metaphysical dilemma to be resolved at the level of ‘us’ versus ‘them’. It isn’t about the right to own land and enforce borders, or the relative worth of individuals versus groups. Instead, the pressures driving immigration should be seen as natural and unavoidable – like chemical reactions; from that perspective, a reduction in the gradients would be the only possible long-term solution…

Arguments for the rights of nations to control their borders are a huge step in the wrong direction. We need to take a hard look at the disruptive dynamics of inequality. If this simple fact of chemistry (that lesser flows to greater) can’t penetrate the predominantly impermeable minds of policymakers, welcome to a world of escalating chaos.

Robert A. Burton considers climate change, economic inequality, political imbalances and other “reasons to move,” as he suggests a more productive way to think about one of this era’s most pressing challenges, one that can be mitigated and made more humane, if not avoided: “Like the chemical process of osmosis, migration is unstoppable.”

As we focus on reducing the gradients, we might recall that it was on this date in 1925 that the Butler Act, prohibiting the teaching of evolution in Tennessee classrooms, became law… paving the way for the Scopes “Monkey” Trial.
