The Day of 8 Billion, officially marked on Tuesday, is a milestone moment for human longevity, according to the UN Population Fund (UNFPA), “signalling major improvements in public health”, but 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 protect people and the planet - starting with the most vulnerable.
