Why are global supply chains so fragile and what causes disruptions?

Global supply chains are like a long train that carries all your favorite toys from one place to another, but if just one car breaks down, the whole train can get stuck.

Supply chains are how things move from where they’re made to where they’re sold. Think of it like a relay race, each person (or country) passes the baton (the product) along until it reaches you.

Imagine you're waiting for your favorite toy, but the train has to go through many stations: first it leaves the factory, then it goes on a big truck, then on a ship, and finally into a store near you. If one of those steps gets delayed, like a storm stops the ship or a truck breaks down, your toy might be late.

Sometimes, things get really messy. A lot of people might want the same toy at once, so there aren’t enough trains to carry them all. Or maybe someone in another country has a problem, like a big fire in the factory, and suddenly no one can make that toy anymore.

It’s like when your friend forgets their lunch, it causes a small delay for them, but if everyone forgets theirs at once, it makes a big mess!
