Climate activist Greta Thunberg banned from Venice after Grand Canal dyed green

Climate activist Greta Thunberg was temporarily banned from Venice after the Italian city's Grand Canal was dyed green in an act of protest. Thunberg, 22, joined environmental group Extinction Rebellion over the weekend when they poured dye into the iconic water corridors that outline the historic city, The Telegraph reported. The dye, a non-toxic tracer often used in environmental studies, transformed the waters of the Grand Canal into a bright green color. The group, in an effort to highlight "the massive effects of climate collapse," hung a banner that read "stop ecocide" from the Rialto Bridge and sent protesters dressed in red veils to walk through crowds of tourists. Dye was also thrown into waterways and fountains in several other Italian cities, including Milan, Palermo and Bologna
