But The Wilderness Society have found a real culprit, and Andrew is not going to like it; the Loggers of the Water Catchment in the Central Highlands:
Logging threatens water supply and qualityWithin the spectacular giant mountain ash forests of the Central Highlands lie Melbourne’s water catchments, which provide drinking water to over 3 million Victorians. Five of these catchments, which supply 40 per cent of Melbourne’s drinking water are open to clearfell logging.
Several independent studies, including a technical report published in December 2000, have found that clearing and regeneration of these forests has a dramatic effect on water yield.
Research has shown logged areas to suffer a 50 per cent reduced water yield (shown in graph). Young regrowth trees need more water to grow, thus releasing less water into river catchments. It takes 150 years for water yields to regain their pre-logged status.
It is breathtaking that in this time of severe drought our most precious resource is jeopardised by logging and that the Government continues to see fit to threaten the little water we have left.

Amazing! It is hard for the U.S. to accept the Science. Reality about global warming and their denial is really a handshaking stuff - agreeing with it.
