World Population Day 2021 is being observed today. This year's theme is, “Rights and Choices are the Answer: Whether baby boom or bust, the solution to shifting fertility rates lies in prioritising all people’s reproductive health and rights." On July 11, 1987, the population of the world crossed the 5 billion mark. This inspired the Governing Council of the United Nations Development Programme to designate July 11 as World Population Day in 1989. The day is observed to spread awareness among people about the population explosion. According to the latest report released by the United Nations, the world’s population is expected to increase by 2 billion people in the next 30 years, to 9.7 billion in 2050 from 7.7 billion currently.
