Today, July 11, is World Population Day. Established by the Governing Council of the United Nation Development Program in 1989, to commemorate the day global population reached five billion two years earlier, World Population Day strives to raise awareness about the issues created by the growing number of people in the world. Twenty-four years later, five billion seems like a distant memory. The global population was estimated at 7,025,071,966 this day last year.
