Good words that express a philosophy essential for Australian society throughout the continent. But meaningless in the face of politicians' deliberate side-stepping of unpalatable fundamental issues:
First, Australia's climate has never been benign in relation to its agriculture, as practiced on its present scale. The last half century is acknowledged as having been a good patch. Perhaps the weather experienced over the last decade might be closer to long-term average. But certainty exists that those elements, already in place, of human-induced drivers of climate change will increasingly exacerbate existing problems until full effect is experienced, in another half century.
Second, agriculture-exported soil nutrients, embodied within produce, to cities and overseas, is not sustainable. These nutrients have to be returned/replaced, needing energy to do so. And phosphorus replacement is a concern.Insufficiency of available phosphorus and cheap energy would have Australian agriculture ceasing as part of world economy.
Third, Australian city and country might haggle among themselves, but are fully interdependent. Pressures upon Australian landscapes arise fundamentally from the weight of city populations and their needs/wants, mostly via direct pressure upon those working the land.
Ever since Charles Darwin's visit, perceptive people recognised problems inherent in an excess of people flogging this continent's limited capacity to provide for them. Twenty million people in 2006 is demonstrably an excess. How many is reasonable? Difficult to say. CSIRO's "Future Dilemmas" provides some options for numbers and consumption. No rosy picture comes out of it for continuing escalation of consumer-economics for ever-growing numbers of people. So I hope (not in expectation) that Andrew Bartlett's fine words about sustainability encompass consideration of Australia's burgeoning numbers (every four years another 1 million, and not enough say the Property/Business Councils).
