Search The Punch keywords http://www.thepunch.com.au/search/ http://www.thepunch.com.au/articles/Seven-billion-reasons-to-think-about-sustainability/ The United Nations estimates that the world’s population will reach seven billion sometime in late October or early November. The sixth billion was arrived at in 1999, and it is significant that the seventh billion took the same number of years (12) to add as the sixth. This is relevant because prior to that, there had been a progressive shortening of the time taken to add billions to the human population. The first billion was reached in 1804, taking many thousands of years of human evolution to achieve. Thereafter successive billions were added in 123, 32, 15 and 13 years respectively. This reflects a slowing down in global population growth from a high of 2.1 per cent per annum in the late 1960s to 1.2 percent per annum currently. feedback@thepunch.com.au (Graeme Hugo) Article http://www.thepunch.com.au/articles/Seven-billion-reasons-to-think-about-sustainability/#comments http://www.thepunch.com.au/articles/Seven-billion-reasons-to-think-about-sustainability/#item7024 Thu, 27 Oct 2011 19:45:41 +0000 Graeme Hugo | Author bios | The Punch
