Yes we are changing, too slowly as far as I'm concerned. Australia is in the grip of its worst ever drought and there is a possibility that towns out west of Sydney will run out of water entirely . In Queensland recently residents voted NO on whether they would be prepared to drink recycled sewage. So the Governments state and federal are in a quandary. One Geothermal Company is getting set to mine the heat rising from the magma which is stored in large basalt Hot Rocks below Sydney Wollongong, Newcastle and parts of South Australia. they plan to bore two wells down to the hot rocks and shatter the rock with hydraulic pressure creating a void between the bottom of the two wells. By pumping water down one well they say they'll get steam up the other which will drive steam turbines. One would hope they could pump sea water down and get fresh water steam coming up leaving the salt sequestered to form rock. Its just a thought the steam could be condensed and become potable drinking water.
