Identify a green infrastructure example.

• A. Wetlands and green roofs
• B. Concrete canals
• C. Asphalt roads
• D. Steel culverts

Answer: (A)

Green infrastructure uses natural systems or nature-based approaches to manage water, reduce flood risk, and provide ecological and social co-benefits in urban areas. Wetlands and green roofs fit this idea well: wetlands store and slowly release floodwaters, naturally filter pollutants, and support biodiversity, while green roofs absorb rainfall, reduce runoff, insulate buildings, and create habitat in cities. Together, they show how built environments can work with nature to manage stormwater and enhance resilience. The other options rely on traditional gray infrastructure that moves water through concrete and metal without delivering those ecosystem services. Concrete canals channel water but don’t offer storage or filtration; asphalt roads are impervious and increase runoff and heat; steel culverts mainly serve as conduits without providing habitats or water quality benefits.
