你是81亿人口中的一员 You are one in 8.1 billion

世界人口日

1987年，世界人口达到50亿大关，这是一个意义非凡的里程碑，由此产生了一个国际性的纪念日：五十亿人口日。伴随着急速增长的人口，一些相关的问题也亟待解决。因此，在1989年，联合国设立了世界人口日。如今，这不仅仅是一个纪念日，更是一个行动的呼吁。人口过剩导致地球的资源越来越少，敦促人类去正视那些紧迫的问题，如计划生育、垃圾和污染的增加、基础设施的缺失等等。当大都市里的人在和“过度拥挤”做斗争时，小地方的人口却在不断流失，导致人口分布失衡。一个典型的案例就是意大利西西里岛的甘吉镇，即今天图片展示的地方。在20世纪50年代，这个村庄大约有1.6万居民，如今，其人口只有6000多一点。为了振兴小镇，吸引人们的关注，甘吉镇将废弃的房屋赠送给那些有需要且愿意修复房屋的人。

World Population Day

In 1987, sometime around July 11, the world population reached the 5-billion mark. The United Nations recognized the need to address issues like family planning, infrastructure, waste, and pollution and established World Population Day in 1989. It is estimated that we hit 8 billion people in November 2022 and the UN expects the world to reach 9.7 billion people in 2050. But not everywhere faces the same challenges. While some areas struggle with overcrowding, others grapple with decreasing populations. The Italian town of Gangi, Sicily, seen in today's image, had about 16,000 residents in the 1950s. Today, it is home to little more than 6,000. Keen on revitalization, Gangi attracts new residents by giving away abandoned houses, on the condition that the properties are then restored.
