I move:

That the Senate take note of the answer given by the Minister for Immigration and Citizenship (Senator Evans) to a question without notice asked by Senator Bob Brown today relating to economic and population growth.

I am grateful to Senator Evans for responding to a question that is very rarely raised in this parliament let alone taken on and answered at some length—and that is the question of the role of population in our future. The former Treasurer, Peter Costello, said that population is destiny. I would agree with that, although I think I am coming from a different point of view.

We are on a planet in which there are now 6½ thousand million people, whereas when I was a lad it was half that amount. At the change from the 19th century to the 20th century there were 2,000 million people, which is less than a third of today’s population. And we know that by mid-century the population is going to be 9,000 million to 10,000 million people. The world advice is that that simply cannot be sustained. We are now looking at rapidly deteriorating food stores on the planet. We are down to fewer than 50 days of flow-on food availability to meet any great emergency, and the number of people facing starvation around the planet right now is in the millions and increasing rapidly, particularly in Africa but also in parts of Asia, like North Korea.

Because energy drives agriculture, and with the onrush of climate change, the very slow growth in productivity compared to population, and peak oil, we will be facing a mammoth, chaotic social outcome of too many people with too few resources on the planet in the lifetime of some of us here and certainly in the lifetime of our children. We are obliged to look at this. That is why I asked the government whether it had a population policy, and I do not believe it does. I do not believe the opposition does. The Greens have one which is very general.

I think it is incumbent upon us all to say what we think about the fundamental supposition that the economy needs a growing population if it is to be sustainable. I think that is a fundamental error but it drives all economic policymaking at government level around the world at the moment. If you take the idea that you must have a growing population to have a healthy economy then the planet will implode because the logic of that is that, if the numbers of humans on the planet keep increasing—and we are the biggest, most marauding group of mammals there has ever been on the planet—to just bring other people up to our level of consumption our current population projections say that we will need not one but three or four planets with the resource base of the earth to sustain human population by mid-century. I am talking about 40 years away. It is simply not sustainable.

We as responsible politicians and representatives of the interests of the future of this nation, if not the planet, have to debate this matter. I believe we have to come to the conclusion that we have to devise economic growth that is not predicated on population growth. If not, we have to state at what level we will stop growing the economy because there are too many people. That is an inevitable outcome of the theory that you must have population growth if you are going to have economic wellbeing. It is a fundamental part of the political discourse and yet it is missing from public debate.

One of my major reasons for raising this question is that I get asked about it all over the country. It does not matter what you are talking about, when you go into any size audience somebody will come up and say, ‘What about population growth?’ So here I am asking that question in the Senate because so many Australians want it debated.

Question agreed to.
