Immigration, Population and Environmentalism

Immigration is one source of population growth, which results in more people to consume goods and services. This larger market is better for local businesses and many migrants bring money into the country and some start up businesses that may offer employment. Many economists argue that, if carefully controlled, this can benefit the nation’s economy and hence, indirectly, our quality of life.

Environmental scientists point out that Australia is already suffering considerable damage to its soils, waterways, coastal zones and natural habitats through intensive agriculture, urban expansion, industrial development and the ever-increasing demand for goods and services. Groups who oppose population increase on environmental grounds suggest that even the present Australian population cannot be indefinitely sustained at its present rate of consumption by the renewable resources of the continent.

I think it's important from an Environmental perspective to cover the issues of not just Immigration, but also the current population in Australia. If I may, I would like to use a very simplistic model to explain problems with over-population.

Firstly, let me talk about my own home. I live with my wife in a two bedroom house. We often have interstate family vistors, or just comrades who need to crash for the night. Although, there seems to be one unspoken rule, and that is, we only ever have people stay in the house when the spare bedroom is free.

We will refer to this as a 'one in, one out' policy.

Imagine, for the moment if we were to accept 10 people to stay in our very small two bedroom home. People would have to sleep on the floor, bathrooms would be in constant use, and the toilet could very well overflow. Issues with kitchen use will arise, and no doubt noise complaints will increase due to the varying hours that people keep in the house. All in all, it would lead to a diminshed quality of life for all parties. Not to mention, that living in such confining conditions would lead to resentment between house mates.

Any of this sound familiar?
I think its time for Australia to work out exactly how many bedrooms it has before trying to increase its population either through immigration or encouraging an increase in birth rate.

If there is only one thing I could ever agree with Pauline Hansen on, its a 'one in, one out' net zero immigration policy. I have continually lobbied for such things, written to ministers, and newspapers. The newspapers (The Age, The Australian), outright refuse to publish my constant letters asking for net zero immigration and population management to raise the issue.

At first I thought it was because they thought I was being "Racist". So I continued to write letters, making sure that I was clear that I didn't care who came into the country, that it was irrespective of race, religion or gender. I also specified that it didn't matter if they were skilled or unskilled, just that we might "look into" the issue. Nothing. Absolute Silence.

The only people who are really benefiting from high levels of immigration are the property developers, big business and all at the expense of the Australian Environment.
I'm dissapointed that the greens party hasn't investigated the impacts of population on the environment and consider policies for population reduction.

What's for dinner? How about our national symbol?

Eating roo could cut greenhouse gas emissions?


A report in the Business Day section of The Age on Thursday, October 11, 2007, suggests that substituting 20% traditional beef with kangaroo meat could help cut greenhouse gas emissions by 15 tonnes per annum.

I've often suggested to people that eating our national symbols would be far better environmentally than eating traditional beef, so this Greenpeace report by Dr Mark Diesendorf comes as no surprise to me.

Firstly, why import and breed animals for food when there is a native species capable of supporting the populations food needs? Secondly, kangaroos are culled in the thousands due to their plague numbers invading farm land. What a waste! Western Australia has started exporting Kangaroo meat, but the industry should think about subsidising the current beef farming industry (in terms of food production rather than their current "delicacy status"). Kangaroos require far less water and are adapted to the harsh Australian climate. Traditional livestock damage river beds when drinking, ruin topsoil through compression with their hooves, and produce high quantities of methane gas (the average cow produces 600L methane a DAY!). Kangaroos being native have a much smaller ecological footprint.

"Australian native wildlife is a renewable resource. If managed in an ecologically sustainable manner, wildlife can provide a perpetual source of economic benefits for all Australians" In fact, Michael Archer Head of the Australian Museum, Sydney, NSW states that "farmers can get filthy stinking rich killing kangaroos".

Although there is still debate about the ability to farm kangaroos, including the amount of meat viable from an animal, and the expense due to fencing costs, it's time to start thinking outside the square. The CSIRO needs to invest more research into the viability of kangaroo farming in the interests of finding a sustainable food source in a country with severe water restrictions and a burgeoning population.
