Japan is still facing a jellyfish problem that is impacting its fishing industry, power plants, and tourism. The increase in jellyfish blooms is caused by overfishing, climate change, and pollution. Measures being taken to combat the problem include using jellyfish as a food source and using robots to remove them from the water. However, their effectiveness is still unclear. Preventing future jellyfish blooms will require reducing pollution, enforcing fishing regulations, and researching ways to control the population. Individuals can also play a role in preventing the problem by reducing plastic waste and supporting sustainable fishing practices.
