[00:00:00]At first glance, this zigzag waterway in South Korea looks like a weird design flaw, but it's actually a [music] lifesaver. This isn't for decoration, and it's not to slow down the river.

[00:00:11]This structure is called [music] a fish ladder. During spawning season, thousands of fish need to swim upstream in the Han River to lay their eggs, but the strong currents and massive water drops act like an invisible wall. That's where [music] this brilliant engineering comes in. These mini pools act like a highway rest stop, allowing the fish [music] to rest, recharge, and jump step. Without it, their entire life cycle would be broken. [music] Genius engineering meeting nature. Would you like to see this in your country?
