UN’s world population estimates raise questions on sustainability
Dec 14, 2010 by ■ Michael Krebs
With population estimates from the United Nations ranging anywhere from 8 billion to 10.5 billion by 2050, there is a need to understand the numbers and the implications of population growth or decline.
As human population figures worldwide are continuing to reflect widespread growth, the United Nations recently released a 240-page report that examines and projects trends over a wide period of time from 1950 to 2300. By 2050, according the UN Population Division analysis, there could be anywhere from 8 billion of us at the low end of the projection to 10.5 billion at the high end.
The impact of these figures on ecological sustainability is not known.
The United Nations has been assessing global populations since the 1950s. As the world settled into a relative postwar tranquility, populations began to expand – and this expansion prompted the UN to begin implementing family planning measures where appropriate.
“The United Nations has a very long history of leading the discussion of population issues at the world level,” UN Population Division Director Hania Zlotnik said. “It started in the 50’s. It culminated in the 70’s with the first intergovernmental conference on population – the 1974 World Population Conference – where governments got together and for the first time they legitimized at the universal level the fact that governments could make policies regarding population and specifically that they had a responsibility to enable couples and individuals to have the number of children they desired – specifically by the rise in family planning programs. And it’s that movement of family planning that has had a major impact on world population trends.”
