What is trade, and why do countries buy and sell things to each other?

Here's a small mystery hiding in your kitchen. The banana came from one country, the chocolate from another, and the little sticker on your apple might have crossed an ocean to reach your hand. None of these things were grown by you, yet here they all are. That quiet daily magic has a name: trade.
Trade is just swapping. You have something I want, I have something you want, so we make a deal and both walk away happier. It's the oldest trick humans know. Long before money existed, a fisherman with too many fish and a farmer with too much wheat looked at each other and thought, "Why don't we trade?"
