World’s population hits eight billion – UN

198

The eighth billionth person on earth will be a baby born somewhere on Tuesday, according to a United Nations prediction.

“The milestone is an occasion to celebrate diversity and advancements while considering humanity’s shared responsibility for the planet,” UN Secretary-General Antonio Guterres said in a statement.

The UN attributes the growth to human development, with people living longer thanks to improvements in public health, nutrition, personal hygiene and medicine.

It is also the result of higher fertility rates, particularly in the world’s poorest countries — most of which are in sub-Saharan Africa — putting their development goals at risk.
