re: water shortage worse with immigration
Average domestic water consumption is about 112 kilolitres per person per annum, but the population growth zealots are silent about the fact that when virtual water consumption is considered (i.e. how much water is used to produce goods consumed) the figure is much higher. The average food intake adds about another 700 kilolitres per person per annum, for example. You could very conservatively estimate that the 150,000 immigrants coming to Australia each year require at least 100 gigalitres of extra water supply or water savings, else living standards will be degraded.
Then there is the potential of permanent rainfall reduction with climate change, remembering that in the Perth catchments, a ten percent rainfall reduction resulted in a fifty percent reduction in rainfall.
zzedzz 80 cents per kilolitre for desalinated water seems optimistically low, but I will run with it. This great for domestic usage, but to hypothetically use this water to produce a kilogram of butter (in reality desalinated water is too salty for agricultural usage) would cost $14.40.
Beware of population growth zealots pushing the imigration driven multicultural utopia. The reality is predominantly white anglo-saxon interests wanting buyers and customers for shoddy housing and supermarkets erected on a vandalised environment. And all Australians are paying for it.
