A wooded area is converted to a housing development and strip mall. Predict and briefly describe three (3) ways this change in land use could affect atmospheric carbon dioxide levels.
What will be an ideal response?
Burning tree limbs or stumps to clear the land releases carbon dioxide. The lack of trees and other plants would cause a decrease in atmospheric oxygen and an increase in carbon dioxide. Fossil fuel combustion would increase from vehicles and store energy use, which would also increase carbon dioxide emissions. With a decrease in the number of trees in a particular area, one might expect a decrease in O2 and subsequently, and increase in CO2. CO2 levels are also associated with rising air pollution. Finally, CO2 is a “Greenhouse” gas that is hypothesized as leading to Global Warming.
