Why are global supply chains still experiencing disruptions today?

Global supply chains are still having problems today because they're like a long train that needs every car to move smoothly.

Supply chains are the paths goods take from where they’re made to where they’re sold, kind of like how your lunch travels from the kitchen to your table at school. But sometimes, parts of this “train” get stuck or delayed, and the whole trip gets slower or even stops for a while.

Imagine you're on a train that goes through many towns. If one town’s track is blocked by a big rock (like a disruption), the train can't move past it, so everyone behind has to wait until the rock is removed. This is similar to how supply chains work when something goes wrong in one place, like factories not making enough toys or ships being delayed at sea.

Sometimes, these delays happen more than once. Like if a train gets stuck, and then another part of the track has a problem too, it’s like having two rocks to move! That makes everything take longer, which is why we still feel the effects today, even after things started getting better.
