UN at 70: Mega-Cities, Mortality and Migration
25 / 02 / 2015, IPS News Environment
As the international community marks the 70th anniversary of the founding of the United Nations, one question worthy of some reflection is: Is world population better or worse off demographically since the establishment of the U.N.? Some contend that the demography of today’s world population is markedly better than it was seven decades ago. Others argue that humanity is definitely worse off demographically and still others – often sceptics and cynics – feel it is neither better nor worse, but just different. This extraordinary demographic growth continues to pose serious challenges for humanity, including food production, pollution, global warming, water shortages, environmental degradation, crowding, reduced biodiversity and socio-economic development. To consider the merits of those various perspectives and distinguish between personal opinions and measurable facts, it is useful and appropriate to dispassionately examine some fundamental demographic changes that have occurred to world population since the middle of the 20th century. Perhaps the most visible demographic change is the increased size of world population, which now at 7.3 billion is five billion larger than at the time of the U.N.’s founding.
