Human Population Grows Up    

Answer:

A model answer has been provided for students' reference. It is strongly recommended that students prepare the answer on their own.   The study of human population as a phenomenon yields many interesting trends and patterns. Human population has never been static but dynamic. Malthus, the famous classical economist observed that human population grows at geometric proportion whereas food grows at arithmetic proportion. The dynamics of human population is influenced by many factors-social, cultural, economic, environmental and technological factors.   According to demographers, between 1965 to 1970 human population growth rate was 2.1 percent per annum which is recorded as the highest. The coming generation will look back at the event as the most significant event in the history of human population. Human population never grew with such speed before 20th century and is never again likely to grow in future.   It will be relevant to present another interesting dimension of the dynamics of human population. Before 2000, young people always out numbered old people but from 2000 onwards old people will have been outnumbering young people. Demographers point out that until 2007 rural people have been out numbering urban people but from 2007 onwards the urban people will be outnumbering the rural people.   Demographers like astronomers keep on observing interesting trends and patterns in human population. As of now human population has been showing inflationary trend, that is, it is growing in size.
