THE HUMAN IMPACT OF MAJOR JELLYFISH BLOOM

Sweden’s Oskarshamn nuclear power plant, which supplies 10% of the country’s energy, had to shut down one of its three reactors after a jellyfish invasion clogged the piping of its cooling system. The invader, a creature called a moon jellyfish, is 95% water and has no brain. Not what you might call menacing if you only had to deal with one or two. … 

Research of 45 major marine ecosystems shows that 62% saw an uptick in blooms (pdf) since 1950. In those areas, surging jellyfish numbers have caused power plant outages, destroyed fisheries and cluttered the beaches of holiday destinations.

The toll we take on the seas may augur a new world order of jellyfish disasters, which, in turn, could devastate the global economy. .. http://qz.com/133251/jellyfish-are-taking-over-the-seas-and-it-might-be-too-late-to-stop-them/
