Explain how the Aryans modified their environment to create fields for planting.

There are three main components that need to exist to create an operational agricultural field:

- Water

- Nutritious soil

- Sun light.

Aryan citizens possess all three of this factors, but some part of Aryan region is located far away from the water source.

So, the Aryan modified the environment by creating an irrigation system.

They build pathway from clay and stones to distribute the water from the river to the field that's located far away from the field. This widen the area of Aryan agricultural operation that led to an increase in overall crops production.
