UN celebrates 8bn birth, says it’s milestone for human longevity
As the world’s population hits eight billion on Tuesday, UN Population Fund (UNFPA) says it’s a milestone moment for human longevity and that it is signalling major improvements in public health.
UNFPA, however, said that it also comes with warnings of worsening economic inequality and environmental damage.
While fewer risks and increased life expectancy are to be lauded, the moment is also a clarion call to look beyond the numbers, and for governments to share responsibility for protecting people and the planet – starting with the most vulnerable.
As the world’s population will continue to grow to around 10.4 billion in the 2080s, overall growth rate is slowing down, according to UNFPA.
However, the planet is more demographically diverse than ever before, with individual countries and regions facing starkly different population trends in growth and decline.
For example, two-thirds of today’s global population live where lifetime fertility is below 2.1 births per woman, while at the same time, population growth continues to surge in the world’s poorest countries – most of which are in sub-Saharan Africa.
“A world of 8 billion is a milestone for humanity – the result of longer lifespans, reductions in poverty, and declining maternal and childhood mortality.
“Yet, focusing on numbers alone distracts us from the real challenge we face: Securing a world in which progress can be enjoyed equally and sustainably,” UNFPA chief Natalia Kanem said.
Whether populations are growing or shrinking, every country must be equipped to provide its citizens with a good quality of life and lift up the most marginalised.
“We cannot rely on one-size-fits-all solutions in a world in which the median age is 41 in Europe, compared to 17 in sub-Saharan Africa.
“To succeed, all population policies must have reproductive rights at their core, invest in people and planet, and be based on solid data,” Kanem.
While the day represents a success story for humanity, it also raises concerns over links between population growth, poverty, climate change and achieving the Sustainable Development Goals (SDGs).
Rapid population growth makes eradicating poverty, combatting hunger and malnutrition, and increasing the coverage of health and education systems, more difficult.
Conversely, meeting the SDGs, especially those related to health, education and gender equality, will contribute to slowing global population growth.
And while several decades of slower population growth could help to mitigate environmental degradation, conflating population growth with a rise in greenhouse gas emissions, ignores the fact that countries with the highest consumption and emissions rates are those where population growth is already slow or even negative.
