The dust bowl started in the 1930's and lasted till the end of 1938. Winds kicked dust up which made a wall of dust. The dust made crops fall apart and die. When you had to go outside and take care of chores or the animals, you would breathe in sand which is bad for your health. It was hard to drive because the walls of sand/dust. That led to shortages in food and supplies needed. Also with the shortage of food being grown the prices of food went up.
