For those of us who feel that Australia is at a crossroad on issues around sustainability the debates related to this topic have been more than a little disappointing – and I am not just talking about the election cycle. The issue of sustainability, carrying capacity and population numbers have all been meshed together to give us a linear equation: less people = more sustainability.

It is a simple equation that then takes us to discussions about numbers: should we have 180,000 migrants or 220,000 migrants? Is a 2.2 percent rise in population sustainable?
Fascinated by these numbers I thought I would try and come up with my own equation to work out the right number of people who should be living in Australia. It goes something like this:
- Take the current population and multiply it by your height (preferably in centimetres);
- Then divide it by the number of contestants on Masterchef plus the number of ingredients Adam (the eventual winner) used in his last dish;
- To this multiply the entire number of times you hear ‘working families’, ‘big new tax on everything’, ‘illegal immigrants’, ‘Nauru’ and ‘moving forward’; and finally
- Multiply it by anything of relevance Mark Latham and Steve Fielding say during this election plus one (the plus one may well stop you multiplying the number by zero).
The number you come up with is about as relevant (and ludicrous) to discussions about the ‘right’ Australian population size as any other number that has been thrown around over the past few years: be it Kevin Rudd’s glee at a population size of 40 million or Kelvin Thompson’s ability to link every evil in the world to population size.
Do not get me wrong, I am not saying that population does not play a role in sustainability but this is simply one of many variables to consider. Here are four reasons why discussions about size fail to deal with the sustainability issues we are confronting.
The first links with resource usage: population size and resource usage are not directly correlated. Yes, we are the driest continent in the world but we continue to grow cotton and other water intensive crops. We do this while over allocating water usage in the Murray Darling as well as allowing millions of tonnes of rainwater to flow away.
By focusing on population size we ignore sustainable resource usage and simply believe that we can keep wasting resources because there are only 22 million of us in this country.
The second point is about the practicalities of controlling population: both from outside and those already here. Immigrant intake is important for both our economy and our society. While the benefits of immigration to our economy are well documented, I am more interested in social factors.
Families come here to settle and build relationships – and these are often strengthened through the arrival of other family members. They build community bonds and these are essential in Australia being a successful nation both economically and socially. Yes, recent migrants often congregate together in certain suburbs, but as we have seen with the Greek, Italian and Vietnamese migrants, within a generation of two they disperse. Migrants have always made Australia a more vibrant society.
Then there is the internal question: even before Peter Costello’s absurd (plasma television) baby bonus, Australia’s population growth rate has been substantial. Do we now control this? Maybe the answer is a “one child policy”? Do we place pressure on families via the tax system to discourage multiple offspring? Maybe those skilled migrants that do come here can sign a pledge to limit their reproduction activities?
To put it directly, taking the position that blames our newest and future arrivals for our environmental problems is simply placing a green coat of paint on excluding outsiders. This is especially the case when applied to the tiny number of refugees we do admit.
The third issue is our global obligations. We are part of a global community and reap the benefits. The challenge of population numbers is an international issue and by simply putting up a fence around Australia and saying ‘no more’ does not solve anything. We rely on the rest of the world for our economic, social and cultural vibrancy – we are unlikely to benefit if we turn our back on such issues and the results are difficult to predict.
Related to this is the issue of justice. Like it or not, Australia is part of a global system that has contributed to refugee flows: our role in Iraq for example and even climate change refugees. When you are part of a ‘shock and awe’ campaign, it is hardly surprising that people want to get out.
Finally there is the issue of the type of Australia we want. The debates take on an air of ‘business as usual’ about them: same economic and planning processes, same levels of resource usage, same attitudes to out cities. It is time we looked at the way we design our cities, develop our housing policies and use our resources in a truly sustainable way – and not rely on cheap slogans to exclude others for the sake of sustainability.
In hindsight, the Indigenous people standing at Sydney Heads and watching the First Fleet arriving in 1788 would argue that the 1,500 migrants were way too many – and this has nothing to do with numbers. As George Mombiot noted, it is “no coincidence that most of those who are obsessed with population growth are post-reproductive wealthy white men: it’s about the only environmental issue for which they can’t be blamed.” It is time we left the numbers debate behind and concentrated on real issues of sustainability.
