An urban planner is designing a new urban housing development. It will have five apartment buildings, two basketball courts, a playground with permeable foam pavers, a 10-acre green space with a small man-made pond, one 5-story parking deck, and direct access to the mass transit train line. Which of the following will best help to reduce the amount of carbon dioxide released into the atmosphere? 1. The land cleared to build the new development occurs in a rural area rather than within the city limits. 2. Access to the mass transit train line will provide inhabitants an alternative to driving personal vehicles. 3. The playground is made with permeable foam pavers rather than with impervious concrete. 4. Food and other resources must be transported to the development from up to 200 miles away.
