Venice's Central Waterway Turns Fluorescent Green, Prompting Investigation

Venetians woke up to an unusual sight as a patch of water in the city's central waterway appeared bright green. Local authorities have collected water samples and launched an urgent investigation to determine the cause.

Speculation ranges from the release of dye to a potential environmental protest. Comparisons are being made to a 1968 ecological stunt when the Grand Canal was dyed green.

What do you think is the most likely explanation for the sudden green color of the water in Venice's central waterway?
