No one would starve... the impact that fast food has is on what is grown and harvested.
McDonaldβs mandates a particular type of potato for thier fries with no blemishes, so the company mandates a certain insecticide that the farmers have learned to stay inside when it is applied.
Coffee growth and harvesting is a brutal business but I am not sure if that can be pinned just on Starbucks.
If the fast food places where denied product I think the long term impact might be on prices..
