The United Nations' (UN) World Population Day is annually observed on July 11 to reaffirm the human right to plan for a family. It encourages activities, events and information to help make this right a reality throughout the world. The primary concern with observing a day entirely as World Population Day was to center attention on the immediacy and consequence of population issues in the context of overall development plans and programs and the need to find solutions for these issues of the effects of growing population. The greatest identifiable threat caused due to over population is the alarmingly fast depletion of natural resources and threat to sustainability. But albeit being a threat to life itself, the World Population is also an opportunity to celebrate the spirit of brotherhood and to realize the responsibility we have towards another in this great big world we call our family.
