The worlds population was to reach 8 billion people on15 November， 2022， representing a“milestone in human de?velopment”before birth rates start to slow， according to a re?port from the United Nations.

In a statement， the UN said the figure meant 1 billionpeople had been added to the global population in just 12years.“This unprecedented growth is due to the gradual in?crease in human lifespan owing to improvements in publichealth， nutrition， personal hygiene and medicine. It is also the result of high and persistentlevels of fertility （生育力） in some countries，”the UN statement read.

Middle?income countries， mostly in Asia， accounted for most of the growth over the pastdecade， gaining some 700 million people since 2011. India added about 180 million peo?ple， and is set to surpass China as the worlds most populous nation in the near future.

But even while the global population reaches new highs， experts note the growth ratehas fallen steadily to less than 1% per year. This should keep the world from reaching 9 bil?lion people until 2037. The UN projects the global population will peak at around 10.4 bil?lion people in the 2080s and remain at that level until 2100. Most of the 2.4 billion peopleto be added before the global population peaks will be born in sub?Saharan Africa， accord?ing to the UN， marking a shift away from China and India.

Having more people on the Earth puts more pressure on nature， as people competewith wildlife for water， food and space. Meanwhile， rapid population growth combined withclimate change is also likely to cause mass migration and conflict in coming decades， ex?perts say.

Resource pressure will be especially daunting in African nations， where populationsare expected to boom， experts say. These are also among the countries most vulnerable toclimate impacts， and most in need of climate finance.
