Impacts of Urbanization - AP Environmental Science

Carbon dioxide (CO₂). Vehicles, industry, and reduced vegetation increase emissions.

Vehicle emissions. Cars and trucks release particulates and toxic gases.

Reduces vegetation cover, lowering sequestration. Concrete replaces forests and grasslands that store carbon.

Light pollution. Artificial illumination disrupts natural day-night cycles.

Increased respiratory problems. Poor air quality from emissions causes lung-related illnesses.

Cycling infrastructure. Bike lanes reduce vehicle dependency and emissions.

Creates microclimates. Buildings and surfaces alter temperature and wind patterns.

Infrastructure expansion. Rapid population growth strains roads, utilities, and services.

Transportation systems. Cars, buses, and trains generate significant sound pollution.

Reduces urban heat effects. Trees and parks provide cooling through shade and evapotranspiration.

Increased housing demand and shortages. Population growth outpaces housing construction capacity.

Reduces air pollution and heat. Plants absorb pollutants and provide evaporative cooling.

Increases pollution and runoff contamination. More impervious surfaces create contaminated stormwater runoff.

Paved surfaces and buildings. Dark surfaces absorb solar radiation and reduce cooling winds.

Enforcing emissions standards. Regulations limit vehicle and industrial pollution levels.

Promoting public transportation. Mass transit reduces individual vehicle emissions per person.

Increases exposure to pollutants. Higher concentrations of air and water contaminants affect residents.

Air pollution. Higher vehicle density and industrial activity increase emissions.

Urban area significantly warmer than its surroundings. Concrete and asphalt absorb and retain more heat than vegetation.

Leads to habitat fragmentation. Development divides ecosystems into smaller, isolated patches.

Reduction in species diversity. Habitat loss and fragmentation reduce wildlife populations.

Constructing retention ponds. Artificial basins collect and slowly release excess rainfall.

The process of increasing population in urban areas. Driven by economic opportunities and better services in cities.

Traffic congestion. Insufficient roads and transit systems create vehicle bottlenecks.

Improves food security. Local food production reduces transport costs and emissions.

Loss of agricultural land. Cities expand outward, converting farmland to development.

Displaces native species. Development destroys nesting sites and food sources.

Mixed-use developments. Combines residential, commercial, and office spaces efficiently.

Decreases soil permeability. Compaction and sealing prevent water absorption and root growth.
