BAD IDEA: Korea's plan to crack down on jellyfish backfires
Korea's jellyfish overpopulation recently clogged up a nuclear plant and forced it to shut down. The country's plan to eliminate their jellyfish epidemic involves using robots to shred thousands of them per hour, but the idea could create even more jellyfish, according to a noted biologist.
Created by researchers at the Korea Science Academy, the robots are called JEROS, which stands for Jellyfish Elimination Robotic Swarm. They work by catching jellyfish in a net and then shredding them in what looks like a rotating fan.
But jellyfish biologist, Rebecca Helm says that shredding them actually creates a jellyfish fertilizer that would only increase the chances of more being born. Helm says, "Assuming you rip through 6,000 jellies per hour for 12 hours, you’ve now released SEVENTY TWO THOUSAND jellies worth of eggs and sperm into the water all at once, rather than slowly over time. And where are those embryos going to go?" Check out this quick video of JEROS at work.

The country is now looking into other ways to get rid of the jellies, such as catching or harvesting them.
