World population

hits 7 billion

 Uploaded by cctvnewschannel on Oct 27, 2011 - The world's 7 billionth person will be born into a population more aware than ever of the challenges of sustaining life on a crowded planet but no closer to a consensus about what to do about it. To some demographers 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.
