Monday, July 11, is World Population Day, a day set aside by the United Nations Development Programme since 1989 to focus on the urgency and importance of population issues globally. In the last 300 years, especially, the world’s population has exploded. According to available records, the world’s population hit the one billion mark for the first time in 1804. It took about 123 years for the world to double its population to two billion. By 1959, however, it increased to three billion, four billion 1974, five billion 1987, six billion 1999 and it hit seven billion by October 2011. It is expected to hit eight billion by 2025.
