Additional Information: This quote is from writer Paul Gilding's 2012 TED Talk in which he discusses the discrepancy between the Earth's dwindling resources and the size of our economy. The quote means that our current pace of economic growth is unsustainable, and as a result, it will be impossible for it to continue. According to Gilding, we would need about 1.5 Earths to sustain the current global economy; thus, a major correction is inevitable. Watch the full TED Talk here: Paul Gilding - The Earth Is Full
