You are one in 8.1 billion. World Population Day

In 1987, the world population reached the five-billion mark, a milestone so significant that it spawned an international observance: Five Billion Day. Back then, the United Nations recognised the need to address the burgeoning issues tied to our global footprint. Thus, World Population Day was established in 1989. Today, it's not just a day—it's a call to action. Overpopulation stretches our planet's resources thin, urging us to confront urgent matters like family planning, an increase in waste and pollution or a lack of infrastructure. While metropolitan areas struggle with overcrowding, smaller places face the problem of decreasing population, leading to an imbalance. One such example is the Italian town of Gangi, Sicily, seen in today's image. This village had about 16,000 residents in the 1950s, but today, it is home to a little more than 6,000. Keen on revitalisation, Gangi attracts attention by gifting abandoned houses to those committed to their restoration.
