Special coverage: World awaits 7 billionth baby
The United Nations says the 7 billionth baby will be born on Oct. 31, 2011. AlertNet, the Thomson Reuters Foundation's humanitarian news website, reports on the challenges of sustaining life on a crowded planet.
With the number of people on earth more than doubling over the last half-century, resources are under more strain than ever before.
And demographers are not even close to a consensus about what to do about it.
To some, the milestone foreshadows turbulent times ahead: nations grappling with rapid urbanisation, environmental degradation and skyrocketing demand for healthcare, education, resources and jobs.
To others, a shrinking population, not overpopulation, could be the longer-term challenge as fertility rates drop and a shrinking workforce is pushed to support social safety for an ageing populace.
