The second geographical feature is the mountains. Greece is a mountainous society. Almost 70 to 80 percent of Greece is covered and dominated with mountains (Aquino & Badilles, 2006). The advantage of the mountains is that they contributed to the preservation of the purity of Greek culture. Because of the mountains, inhabitants of ancient Greek civilization were secluded to their area resulting to rare interactions with other cultures. One bad effect of this geographical feature is that it served as a natural barrier which acted like walls separating different communities. It hindered communication among communities and slowed down the introduction of new ideas and technology. It also obstructed the development of a unified system of government. The Greeks ingenious solution to this problem is to developed the polis or the city-state. The creation of the city-states indicates the start of Greek's classical age because the emergence of the polis started the numerous great achievements of the civilization (Willis, 1985). It also proved that democratic government works better in smaller states (Willis, 1985). Every polis has its own government and laws and it helped promote people's participation in political affairs. It also provided protection and security to the inhabitants. Because states are smaller, the demands and needs of the people were easily reflected in the laws and policies that the government established. Another disadvantage of this geographical feature is that only few lands were dedicated to farming. Few small valleys and plains of ancient Greece provided farm land for the people. Adding to the disadvantage is the the rocky lands and poor soil which are not suitable for the domestication of plants. Although they experienced such disadvantages in farming, they still tried to cultivate olives and grapes. They also domesticated sheeps and cattles as an alternative to farming. The development of the polis also helped in their dilemma because it allowed them to supply enough food for the smaller population.
