Agriculture was also poor many farmers left the farmland to find work in the city. As new people emerged, new demands also appeared. Instead of fresh fruits and vegetables, Americans preferred cereals and bread which lead to the decrease of demands in fruits.
In the 1920s, Argentina and Canada began to supply the world crops which lead to the drops of demands from USA directly.
