Answer:
The land is poorly suited for farming--most people living on the steppe survive by herding animals.
Step-by-step explanation:
The Mongols began their nomad journey because of the unavailability to settle in a fertile region where they could promote agriculture. In this way, most of the population suffered from grazing animals and lived migrating from region to region looking for water for themselves and animals, as well as looking for pastures so that animals could eat. This established a very difficult and precarious life, where people and animals suffered from the lack of resources necessary for their survival.
