12. GoJelly, an EU-funded project, discovers that jellyfish might provide a solution to the pollution. It started the research when seeing jellyfish mucus, a sticky substance emitted by a jellyfish, used in an experiment nanoparticles successfully. The subsequent tests suggest that the mucus also has the potential to absorb microplastics. This way to use jellyfish to produce microplastic filters is innovative. The inspiration, 13 comes from another environmental threat-jellyfish bloom. Jellyfish block pipes at power plants and overwhelm fisheries and therefore are often considered 14 . Global warming worsens the problem and the number of jellyfish is on the rise. GoJelly sensibly takes “advantage” of this threat to combat the man-made threat. It also hopes to 15 people's stereotype about jellyfish and use the potential of the huge biomass drifting right before our front door," said the initiator of GoJelly.
