The Eco Incredible Incas

Making their home in the South American Andes mountains, the Incas were incredible.
The Andes are, without a doubt, some of the most beautiful mountains in the world. But for all their glory, they are also some of the most stark and barren. Yet, the Inca were able to cultivate and reap immense harvests from the Andean sharp slopes and scattered waterways. They developed hearty varieties of crops, such as potatoes, quinoa, maize and corn. They built irrigation canals that wound around the mountains. They carved out terraces into the hillsides, so that no matter how much it rained (and it does rain A LOT here), each growing bed never flooded while maintaining the perfect amount of moisture.
