Quote from CCSA's Blueprint for a Sustainable Future, planning and development.
"Between 2001and 2006 South Australia's population grew at an average annual rate of 0.74%, whereas the number of private dwellings grew by 1.14% per annum. The average number of persons per private dwelling decreased with projections suggesting a further decrease causing an increase demand for housing at a faster rate than population growth. These trends mean Australians use more water and energy, and own more cars per person than almost any other country in the world.
This type of behaviour is no longer morally justifiable, economically affordable, or environmentally prudent. In short, it is not sustainable. To counteract and re-invent ourselves in the face of the threats posed by climate change and the end of cheap oil is a necessity. We can plan our future - or be left to simply react when it arrives. It's a simple choice."
