What combination of factors could cause another dust bowl in the future

1. Dry conditions caused by global warming.

2. The decrease in value of current forms of currency.

3. A stock market crash, which is when too many people want to sell stocks in companies, and not enough people want to buy them. This results in the devaluation of currency. In simpler terms, no one has any money, because no one has any money to pay the people who don't have any. In addition, no one is buying products, because they can't pay, so businesses have to close.
