Sustainability discussion question | Marketing homework help

Take a look at The World is Not Enough link.  It shows how much land would be needed if all of the people in the world consumed like the average person in Indonesia or the average person in the US.  Bottom line, if everyone in the world consumed like Americans, we would need 5 Earths!  Given that we only have one Earth, and that Globalization is “a rising tide that lifts all boats” what are your thoughts on what needs to happen next?  What would happen if every country was as rich as the US and consumed resources like people in the US?  How does this related to the Sustainability topic you’ve read about?
