The world’s population has reached eight billion people, the United Nations has said, warning of more hardship in store for regions already facing resource scarcity because of climate change.
Reaching eight billion people is “a sign of human success, but it’s also a great risk for our future,” said John Wilmoth, the director of the UN’s population division on Tuesday.
Middle-income countries, mainly in Asia, accounted for most of that growth, gaining some 700 million people since 2011.
