Why do we have to do anything for these " poor impoverished starving countries " ?
A couple of small reasons really.
A. Paris agreement. Reducing CO2 emissions and all that stuff.
B. Do you mean all those countries that make stuff that we import ? All those countries that are supplying cheap labor for Australia ? All those countries that buy our coal, lng, agricultural products etc ? All those countries that send their kids to study in Australia ?
Etc, etc.
Sorry I had to explain that for you. Anything else you need explained ?
