Answer 1

Population growth can have both positive and negative effects on sustainable development.

- Positive impacts: a larger population can expand the labor force and domestic markets, spur innovation and entrepreneurship, create economies of scale for infrastructure and services, and increase the fiscal base for public investment.

- Negative impacts: it raises demand for goods and services (food, water, energy, housing, healthcare, education, transport), puts pressure on natural resources and ecosystems, increases waste and pollution, and can push up costs for housing, food and public services. Rapid growth can also create obstacles such as higher unemployment, inadequate public services, slums and informal settlements, and greater vulnerability to climate and environmental shocks.

Which effect dominates depends largely on policy and institutions. Policies that help steer population growth toward sustainable outcomes include investing in education (especially for women and girls), accessible reproductive and health services, green and resilient infrastructure, efficient resource use and waste management, inclusive economic opportunities, and smart urban planning. These measures help capture the economic benefits of a larger population while reducing environmental and social costs.
