Answer 2

I can't say the biggest cause, but the causes are drought, strong winds, stock market crash, and e.t.c.
If I will say what caused it, It would be the stock market crash or drought.
It depends on the person. If it was a farmer or rural person they will most likely be affected the most by the drought. If it was a business person they will be most likely most affected by the crash of the stock market.
