Because of the Great Depression it caused many problems. One of the many problems is hunger.
This hunger was caused by people not having enough money to buy food.
The Stock Market had crashed which lead to banks failing. The banks failing left people with no money and no jobs.
Since people were living in poverty, they were forced to build small houses that weren't too expensive so they could also buy food and necssesities..
A good solution for helping out would to have the government step in and set up things such as soup kitchens to help cut down the numbers of those in hunger.
