Tous à Zanzibar

Posté le Dimanche 8 janvier 2012 par Letel

In 1950 the whole population of the earth—2.5 billion—could have squeezed, shoulder to shoulder, onto the Isle of Wight, a 381-square-kilometre rock off southern England. By 1968 John Brunner, a British novelist, observed that the earth’s people—by then 3.5 billion—would have required the Isle of Man, 572 square kilometres in the Irish Sea, for its standing room. Brunner forecast that by 2010 the world’s population would have reached 7 billion, and would need a bigger island. Hence the title of his 1968 novel about over-population, “Stand on Zanzibar” (1,554 square kilometres off east Africa).

Brunner’s prediction was only a year out. The United Nations’ population division now says the world will reach 7 billion on October 31st 2011 (America’s Census Bureau delays the date until March 2012). The UN will even identify someone born that day as the world’s 7 billionth living person. The 6 billionth, Adnan Nevic, was born on October 12th 1999 in Sarajevo, in Bosnia. He will be just past his 12th birthday when the next billion clicks over.

That makes the world’s population look as if it is rising as fast as ever. It took 250,000 years to reach 1 billion, around 1800; over a century more to reach 2 billion (in 1927); and 32 years more to reach 3 billion. But to rise from 5 billion (in 1987) to 6 billion took only 12 years; and now, another 12 years later, it is at 7 billion (see chart 1). By 2050, the UN thinks, there will be 9.3 billion people, requiring an island the size of Tenerife or Maui to stand on.
