"You are living in a fantasy land if you cannot understand this. "
Very amusing and a good effort towards winning the HC 2019 "Irony award".
However, you didn't show how any of your fantasy claims about changing the current Australian political reality will solve the issue of increasing Human population ... which was the question posed.
Let alone the idealistic pie in the sky hope that the lip service Paris accord will actually mitigate anything to do with the climate.
As for Australia taking control of the World's direction by becoming the leader in renewable technology ... sorry that's just another fantasy to make you feel better and avoid facing reality.
Pretty silly to propose unrealistic scenarios and then claim others who don't join you in waving the toy flag are lacking understanding because your scenarios are fantasy.
At least @RedCedar is building a backyard BBQ Nuclear reactor which is much more practical than your suggestions, though it's still not clear how that will reverse the Human population growth issue that was raised.
