Detailed explanation-1: -Hunter-gatherers had a powerful effect on their environment. Over-gathering of certain plants and seeds caused those plants to become more scarce. This negatively impacted the animals who fed on those plants as they would have had much less food to eat.

Detailed explanation-2: -One way they adapted their diets was by enriching meals with fat. To protect themselves from the harsh environment, they learned to build sturdier shelters. They also learned to make warm clothing using animal furs. Paleolithic people used fire to help them stay warm in this icy environment.

Detailed explanation-3: -In search of new resources: If they stayed at one place for a long time, they would have eaten up all the plant and animal resources available at that place. In search of animals: As animals move from place to place in search of food, hunters also move to chase them for hunting.
