Why is global supply chain resilience a major economic concern now?

Global supply chain resilience is like having a strong backpack for your trip to the park, you want it to hold up even if something goes wrong.

Imagine you're making your favorite sandwich: bread, peanut butter, and jelly. You get the bread from one store, the peanut butter from another, and the jelly from a third. Now imagine all those stores suddenly close or can't send their stuff on time, poof, no sandwich! That's what happens when supply chains break.

A supply chain is like a team of friends passing around toys during recess. Each friend has a job: one gets the toy, another fixes it, and the last one gives it to you. If one friend can't do their job, maybe they're sick or lost their shoes, the whole game slows down.

Today, many of these "friends" are far away, like in different countries. When problems happen, like a storm, a fire, or even a virus, it's harder for them to send their toys (or bread, peanut butter, and jelly) on time. That makes things more expensive and harder to find.

So, supply chain resilience is about making sure those friends can still pass around the toys, even when something goes wrong, keeping your sandwich (and economy) strong!
