Why have global supply chains become so fragile in recent years?

Global supply chains are like big toy trains that move toys from one place to another, but lately, they've been getting stuck more often.

Imagine you and your friend have a game where you pass blocks back and forth across the room. You both need the same block to build something cool. But if your friend drops the block on the way, or the floor gets messy and you can’t see it, the game stops, just like supply chains when things go wrong.

1. Too many people playing at once: There are more trains (companies) trying to move toys (products) than before. If too many trains try to use the same track at once, they get backed up, that’s like more factories making things but not enough trucks or ships to carry them.

1. The tracks got broken: Some parts of the world had big problems, like a really cold winter or a fire in a warehouse, it's like someone knocked over your tower, and now everything has to be rebuilt from the bottom up.

1. Some trains are going too fast: Companies try to move toys as quickly as possible, but if they go too fast without checking the tracks, they might crash, just like when a truck breaks down on a busy highway.
