Protesters from the Extinction Rebellion group were branded “eco vandals” by Venice’s Mayor Luigi Brugnaro after pouring green dye into the city’s Grand Canal on December 9.Similar protests were seen along waterways in Rome, Milan, Turin and Bologna, as the group criticized what it said was the inaction of governments at COP28.The dye used was “a simple fluorescein. A harmless salt used by plumbers as a tracer and even to signal the position of divers lost at sea,” a spokeswoman for the group said.“In a few hours, these waters will return to how they were before. The color of our seas and rivers, however, will continue to change as temperatures continue to rise," the statement continued. Credit: Extinction Rebellion Italy via Storyful
