The Dust Bowl was a huge thing many years ago. There was actually a huge circle on many maps that were drawn showing where exactly the Dust Bowl was located. Many farmers/ civilians moved away from this location due to the fact that it was very hard to grow crops and it was a very miserable life style for all who lived within the circle. Anyways, it impacts farmers by causing them to lose many, if not all their crops. If they had any crops, they were very low quality. I hope this helped! :)
