We can save the small remaining part of nature which can be saved and make Australia egalitarian again, by taxing the rich according to Northern European norms (inheritance and wealth taxes) and raising welfare support by 60% to the OECD average.

Red meat production is causing environmental pollution and global warming.

Great big new wealth and inheritance taxes. Intelligent, humane people would plan for the planet to thrive for a few more million years.
