Jellyfish swarm northward in warming world!

This year’s jellyfish swarm is one of the worst seen. Once considered a rarity occurring every 40 years, they are now an almost annual occurrence along several thousand kilometers (miles) of Japanese coast, and far beyond Japan.
The venom of the Nomura, the world’s largest jellyfish, a creature up to 6 feet in diameter, can ruin a whole day’s catch by tainting or killing fish stung when ensnared with them in the maze of nets.
Addressing the surge in jellyfish blooms in most places will require long-term fixes, such as introducing fishing quotas and pollution controls, as well as capping greenhouse gas emissions to control global warming.
What do you think should be done?
