World’s population to reach 8 billion in few hours — UN Secretary-General Antonio Guterres

UN Secretary-General, Antonio Guterres, on Tuesday projected that the world’s population would reach 8 billion by the end of today, November 15.

The UN press release said “it is a milestone in human development. This unprecedented growth is due to the gradual increase in human lifespan owing to improvements in public health, nutrition, personal hygiene and medicine.’’

While it took the global population 12 years to grow from 7 to 8 billion, it will take approximately 15 years, until 2037, for it to reach 9 billion, a sign that the overall growth rate of the global population is slowing, said the release.

“The milestone is an occasion to celebrate diversity and advancements while considering humanity’s shared responsibility for the planet.’’ It is also the result of high and persistent levels of fertility in some countries,” the report added.

According to the report, countries with the highest fertility levels tend to be those with the lowest income per capita.

Global population growth, has therefore over time become increasingly concentrated among the world’s poorest countries, most of which are in sub-Saharan Africa.

It reads that population growth magnifies the environmental impact of economic development, while rising per capita incomes are the main drivers of unsustainable patterns of production and consumption.

“Yet, slower population growth over many decades could help to mitigate the further accumulation of environmental damage in the second half of the current century,” said the release.
