Optimum Population


Population control is a rather unpopular idea, which remains haunted the spectre of Thomas Malthus whose apocalyptic projections famously never saw realisation. To this day any suggestion of population control or of the mere existence of an overpopulation problem is likely to be dismissed as neo-Malthusian pseudo-science.

In 2009 naturalist and TV producer David Attenborough, of whose documentaries I am quite a fan, stirred up a bit of controversy when he joined a small charity (bringing the oxygen of publicity with him) called the Optimum Population Trust (OPT).

I would argue, in defence of the OPT, that population level, and far more importantly rate of population growth, is a significant concern worthy of both scientific investigation and political action. Consider, for example, the level of criticism often levied at the People’s Republic of China (somewhat unfairly, in my opinion) for it’s rapidly growing level of CO2 emissions. Now if it were not for the highly controversial population control laws applied in parts of mainland China, the population of the PRC would be 300-400 million greater than it presently is. Accommodating for such a larger population with the currently existing standard of living (including the same availability of domestic electricity per person) would require drastically higher levels of CO2 emissions (as the population increase would be almost entirely urban). Not increasing the power generation capacity in proportion to the population increase (which would be economically infeasible anyway) would result in greatly reduced standards of living for all concerned.

This ecological argument is the focus of all modern population control efforts, including the OPT. The ecological population problem differs from the Malthusian population problem in that whereas the latter is resolved through the exponential increase in productivity from industrial capitalism, the ecological crisis is often caused by that very increase in productivity (especially in major developing economies such as China).

All this, then, if perhaps not scientifically conclusive on its own, suggests that further investigation into the potential problem shouldn’t be neglected and that great consideration should be given to efforts to reduce the global birthrate, or even better to address the climate change issue directly (and no, asking developing countries to develop less slowly while much of their population lives in poverty is not a solution).

The problem, however, is that the OPT seem to be preoccupied with campaigns which fail to address this commendable goal in any realistic way.

Firstly, I shall address the issue of their views specifically on the United Kingdom population. The UK is a densely populated country, there is no denying that. There is also no denying the fact that the population of the UK is increasing, and that net migration into the country plays a role in that. It does not, however, logically follow that it is necessary to “[bring] immigration into numerical balance with emigration” (in other words, adopt a draconian immigration policy).

Limiting immigration to the UK does not tackle global population growth (as residents in the UK, including later-generation migrants are likely to have less children that those who live in countries from which the UK receives most of its immigration, it would actually have a slight impact of increasing it). Is there a specifically UK population crisis? If so the OPT fails to make the case for it convincingly. Yes, our population has long outgrown our domestic ability to produce sufficient sustenance and to handle all our waste produce, however we are not and are unlikely to ever be dependent solely on the natural resources of Great Britain and two-thirds of Ulster.

Further restricting immigration to the UK actually defeats what was presumably its purpose. The OPT cite the ageing of the UK population as a serious concern, however restricting immigration would make this worse, by eliminating a major source of young working-age adults and their children.

The OPT could make the argument that severely limiting immigration to the UK is in the interest of its ‘native’ population (although the evidence doesn’t seem to support that position) but the OPT should realise that this not a scientific position but a political one (and a rather unpleasant one at that).

Secondly, beyond positive support for the improved availability of family planning and birth control resources, the OPT’s approach to the global population problem is thoroughly disappointing. Their “Stop at Two” campaign just seems patronising, as though third world families have many children through ignorance, rather than economic necessity.

When I first heard of the Optimum Population Trust (through the Attenborough controversy) I was interested in joining, but after reading their material I though better of it. Should they come up with some genuinely inspired campaigns and overcome their flirtations with national-chauvinistic sentiment (which I’m sure is just badly thought out policy making rather than genuine malice) I would happily take out a membership card but until then I’ll opt-out.

    Good point. While a critical and open discussion about global and regional populations needs to happen, immigration control is not an effective way to achieve ecological benefits. I’d much rather see a useful discussion and campaign for women’s education and family planning in developing countries – there are benefits to such initiatives well above and beyond the ‘population limitation’ side, and it would be a much easier pill for the public to swallow than immigration control.
