To the New York Times : ” The population of the world, long expected to stabilize just above 9 billion in the middle of the century, will instead keep growing and may hit 10.1 billion by the year 2100.”
” Growth in Africa remains so high that the population could than triple in this century, rising from today’s one billion to 3.6 billion, the report said — a sobering forecast for a continent struggling to provide food and water for its people.”
“The new report comes just ahead of a demographic milestone, with the world population expected to pass 7 billion in late October, only a dozen years after it surpassed 6 billion.” More at the UN website.
