How did the Inca change their environment?

The Inca significantly altered their environment through advanced agricultural practices, including the creation of terraced farming on steep mountainsides, which maximized arable land and minimized soil erosion. They also constructed an extensive irrigation system to manage water resources effectively, allowing them to cultivate a variety of crops at different elevations. Additionally, the Inca built roads and bridges that connected their vast empire, facilitating trade and communication while reshaping the landscape. These changes enabled the Inca to sustain a large population and thrive in diverse ecological zones.
