2. How did South American begin to build a more stable food supply?

Answer 1

South America began to build a more stable food supply through practices such as agriculture, animal husbandry, and trade. Indigenous peoples in South America, such as the Inca, Maya, and Aztec, developed advanced agricultural techniques such as terracing, irrigation systems, and crop rotation to increase the productivity of their land. They also domesticated animals such as llamas, alpacas, and guinea pigs for food and other resources.

Additionally, South American civilizations engaged in trade networks to exchange goods and resources, allowing them to access a wider variety of foods and secure their food supply. This diversification of food sources helped stabilize their food supply and prevent shortages during times of scarcity.

Overall, through a combination of agricultural innovation, animal husbandry, and trade, South America was able to build a more stable food supply and sustain its populations over time.
