Chicago River in US dyed bright shade of green; here's why

Chicago River in the US has been dyed a bright shade of green. Why? Read to find out.

The Chicago River was dyed a bright shade of green Saturday after Mayor Lori Lightfoot reversed an earlier decision not to tint the waterway for second year because of the coronavirus pandemic. Crews on boats began dumping green dye into the riverfront about 7 a.m. after Lightfoot authorized the dyeing ahead of St. Patrick's Day, delighting pedestrians with the vivid scene. Chicago residents Lori Jones and Mike Smith surveyed the green waters, saying they were glad the tradition that dates to 1962 was resumed this year.
