So many people on this thread are making the following 2 fallacies:
1) That Earth is the only possible source of resources - ignoring entirely the rest of the Solar System and indeed the universe
2) That a finite resource availability means that we need to go to 0% growth absolutely right this moment or else impending doom and disaster.
Also unbelievable how many people think that economic growth doesn't help the poor. Hint: compare the poor of any country in the world today to that of 500, or even 50, years ago. Only those countries purposely run into the ground e.g. North Korea, or in extreme conflict zones e.g. Somalia, have their poor worse off.
