Here is my assignment: Give an example of a left-shift in a supply curve for a real market (not a textbook example) with a source. Attach a picture of a hand-drawn supply and demand diagram with the effect of your example on a market.

I am not as concerned how I can personally achieve this as much as o finding the numbers to complete this problem. I thought of using the baby formula shortage as an example but I cannot find the numbers on that to make the diagram.
