Answer:
D. to expose the environmental threats posed by ridgetop development
Explanation:
The essay that is presented has the purpose to expose the threats that come in with the development of the ridgetops. The ridgetops are very attractive for development because they have very nice locations, are very beautiful naturally, and have excellent view. Unfortunately, the ridgetops are not safe for development, as very often the soil and rocks are not suitable for supporting heavy buildings. They are also risky after they are cleared from vegetation because of the intense erosion and danger of landslides. The environment is heavily affected by the ridgtop development as whole communities are destroyed, and the ridgetops are totally reshaped forever.
