A section of the Grand Canal in Venice (Italy) turned fluorescent green on Sunday. The color change was reported by locals, according to the president of the Veneto region, Luca Zaia.
The prefect of Venice ordered an intensification of surveillance in the lagoon to monitor any critical problems and prevent similar episodes in the future. Police are looking into whether climate change activists may be behind the phenomenon. In 1968, the Argentine artist Nicolas Garcia Uriburu dyed his waters green with a fluorescent dye during the 34th Venice Biennale.
