When a city expands, more houses and buildings are built to meet the demands of new residents and business that are moving into a location. In order to construct new building, heavy vehicles are needed to clear land and begin construction. These heavy vehicles emit CO2 into the atmosphere. CO2 is a greenhouse gas which is part of the greenhouse effect that causes Global Warming. The greenhouse effect is the process by which absorption and emission of infrared radiation by gases in the atmosphere warm a planet's lower atmosphere and surface ("Global Warming", 2013). In addition, new buildings cause indoor pollutants that are released through air vents, open doors, and open windows. These pollutants include formaldehyde (H2CO) from carpet and plywood, as well as, volatile organic compounds (VOCs) from paint and solvents...
