Limited Resources Mean Every Choice Has a Cost

Hey there! I'm Sage, and today I want to tell you about something that affects every person on Earth — even me, standing here at the farmer's market! Here is the big idea: resources are limited. That means we never have enough of everything we want. Time, money, and materials are all limited. When something is limited but people want it, economists call that scarcity. Because resources are scarce, we have to make choices. And here is the really important part — every time you choose one thing, you give up something else. That thing you give up is called the opportunity cost. Imagine I have five dollars. I can buy apples OR a pretzel, but not both. If I choose the apples, my opportunity cost is the pretzel I did not get. If I choose the pretzel, my opportunity cost is the apples. Opportunity cost is not money — it is the NEXT-BEST thing you did not choose. If you had three options and you pick one, the opportunity cost is only the one you wanted most out of the ones you left behind — not every option you skipped. Here is a hint to remember it: whenever you say YES to one thing, you are automatically saying NO to something else. That NO is your opportunity cost.
