Most people in Southeast Asia live near river deltas and on volcanic islands because these areas provide fertile land for agriculture and access to water for transportation and irrigation. The river deltas in Southeast Asia are rich in nutrients and often have fertile soils, which make them ideal locations for growing crops. Additionally, volcanic islands typically have rich soils and a warm, humid climate that is perfect for growing a wide variety of crops. The proximity to water also makes these areas ideal for transportation, trade, and fishing. Furthermore, volcanic islands often have natural harbors and protected bays that make them ideal locations for ports and naval bases. As a result, these areas have become centers of economic activity and human settlement for centuries.
