A larger population requires more resources (food, water, energy), more land for housing and agriculture, and generates more waste. This increased demand and activity lead to the clearing of forests (for agriculture, logging, and urbanization), expansion of urban areas (urbanization), and increased generation of pollutants from industrial activities, transportation, and waste. While greenhouse effect, global warming, and ozone depletion are serious environmental problems, they are largely consequences of human activities driven by population growth and consumption patterns, not the primary causes of forest loss, urbanization, and pollution increases themselves.
