This document discusses population explosion as a threat to national security in Pakistan. It notes that Pakistan's population has grown rapidly from 45.9 million in 1960 to 178.9 million in 2012. This high population growth rate puts pressure on resources and can contribute to issues like poverty, unemployment, and social problems. If not addressed, an overpopulated country like Pakistan may face threats to national security and economic instability. The document advocates for family planning programs and increasing education and awareness to help control the population growth rate.
