16. What challenges did they face? Name at least one major impact the Natufians had on the environment.

The early humans, the natufians, were challenged with climate change. The ice age limited their supply of food and made them search for a new supply of food. Because of the ice age, the earth became more fertilizable that provided more resources. So the Natufians didn’t only adapt by making new tools – they also instead of travling around all the time now settled down in one place. They no longer had to follow the food. They then had more permanant homes and didn't really have to worry about starvation.The new food they discovered was called grain. Now in 3 weeks one person could harvest enough food for a family for an entire year. The natufians positivly affected the enviromemt by planting seeds in the ground. The natufian people were known as the first farmers.
