By the end of next year, India will surpass China as the world's most populous nation. According to a projection from the UN, India will surpass China as the country with the largest population. The world population will surpass the 800 crore mark by the second half of November this year. Antonio Guterres, secretary general of the UN, emphasised that everyone has a responsibility to safeguard the environment while noting that life expectancy is rising and maternal mortality is down. According to the World Population Prospects 2022 report by the Population Division of the UN Department of Economic and Social Affairs, the world's population will be eight billion by mid-November, 8.5 billion in 2030, and 9.7 billion in 2050. It is anticipated that the world population will reach a peak of roughly 10.4 billion people during the 2080s and then remain there until 2100, expanding at its slowest rate since World War II.
