Answers
The price of gas today is very low. Which one of the following is a
potential unfavorable environmental outcome that could result
from today's low gas prices. Ans: Lower prices could encourage
drivers to take more frequent and-or longer road trips.
This is not a consequence of urban sprawl: Ans: Lower incidence
of obesity and high blood pressure
How might coral bleaching in the ocean be caused by urban
sprawl? Ans: Cutting down trees-->Decreased removal of CO2
from atmosphere-->increased CO2 in atmosphere-->increased CO2
