A swarm of jellyfish forces three nuclear reactors to shut down in France: Here's why

Why are jellyfish becoming a concern? Experts say overfishing, plastic pollution and warming seas linked to climate change have created conditions that allow jellyfish to thrive and reproduce. France’s nuclear output has also been disrupted this year by heatwaves and droughts. Before the latest closures, nuclear production was 15.6% below normal on Sunday, according to AFP calculations based on EDF data. (Image: AFP)
