Which action is explicitly listed as improving urban sustainability?

• A. Drive alone to work.
• B. Convert parks to parking lots.
• C. Build more highways.
• D. Use public transportation.

Answer: (D)

Promoting urban sustainability often hinges on reducing reliance on private cars and expanding efficient transit. Using public transportation directly lowers the number of vehicles on the road, which cuts fossil fuel use, reduces greenhouse gas emissions, and eases traffic congestion. It also tends to use land more efficiently and supports healthier, more livable neighborhoods when paired with good infrastructure and green spaces. Driving alone increases fuel use and emissions and adds to congestion. Converting parks to parking lots removes valuable green space, worsens heat island effects, and harms urban biodiversity. Building more highways can encourage more car travel, expand land use for roads, and often undermines sustainability goals by increasing emissions and dependence on motorized transport. So, using public transportation is the action that improves urban sustainability.
