This document discusses some of the negative impacts of urban sprawl such as increased cost of living, resource consumption, water pollution from agriculture and waste, and air pollution from reliance on automobiles and industry. It notes that pollution can come from point sources like factories or non-point sources like runoff. Urban sprawl is also linked to health issues like respiratory illnesses that disproportionately impact the elderly and young. Some proposed solutions include promoting smart growth to reduce car dependency, creating sustainable cities that allow walking and transit, and educating communities to encourage sustainable development.
