How does scarcity affect your life? provide several examples of items you had to do without because of limited resources. explain how you adjusted to this situation. for example were you able to substitute other items for those you could not have?

Just an idea for you to work with - but depending where you live certain fruits and vegetables may be scare enough that the price would rise because what is there has to be imported. IE., tomatos are least expensive in the summer and expensive in the winter and also don't taste as good as homegrown.  

Here's another - during hurricane season the price of plywood rises because it is scarce (depends on where you live) The trickle down economy of this in the case of an active hurricane season means that all lumber products become scarce and more expensive - even that wooden 24" shelf at Home Depot will cost you more $.

the answer would be in this answer. someone already asked the question.  

using the scientific method.
