Rapid population growth is a significant obstacle to development in many poor countries. It leads to problems like environmental degradation as population and consumption levels rise, as well as economic stagnation as infrastructure and social services struggle to keep up with high birth rates. High fertility also contributes to issues like maternal mortality, youth unemployment, and political instability. While population growth alone does not cause poverty, it exacerbates development challenges. Reducing population growth through access to education and family planning is crucial for improving living standards in developing nations.
