The study looked at how population growth and urbanization impact the environment and economy in South Asian countries from 2000 to 2018. The researchers found that environmental degradation hurts economic growth, while urban population growth helps it. They also discovered that there is a two-way relationship between population, urbanization, environment, and economic growth. Additionally, population, urbanization, and economic growth contribute to environmental degradation in these countries. The study suggests that collaborative efforts among these countries are needed to boost economic growth and address environmental issues.
