Read the Following Scenario and Answer the Questions Below

Read the following scenario and answer the questions below.
Northeast of Australia and northwest of Fiji lies the isolated tropical island of Tikopia. Less than two square miles in length, it supports 1,200 people and has been continuously occupied for nearly 3,000 years, with the population holding steady for much of that time. It has a two-month dry season every year and lies in the Pacific's cyclone belt, which destroys homes and gardens on an unpredictable but regular basis. Tikopia is too far away from other islands to have any regular contact; the islanders must be self-sufficient.
-Tikopians should be particularly concerned about sustainable land management because ____________.

A) the population is threatened by global climate change
B) the nearby islands have likely already been overharvested
C) the annual dry season could kill the tropical plants if they are not well maintained
D) tourists would not want to visit an island that has been decimated by human activities
E) tropical cyclones could permanently harm the island's ability to sustain the local population
