The Dust Bowl occurred because of many factors, not just one. Most of these factors were caused mainly by the human race. Farmers didn’t plan very well, and they just kept uprooting dirt in the same spots. By tearing up the ground, there was dry dirt on top of the fertile soil. On top of that, there was not much rain in the Great Plains, where the soil was being dug up. Then the wind started to speed up, pick up the dirt to massive heights and spread 1,800 miles wide. Houses, farms, cities, etc. where covered in dust from the dust storms. A lot of people suffered from what was called dust pneumonia. In 1939, rain began to fall and conservation techniques were put into play to prevent Dust Bowls to happen again.
