Four of the five most polluted cities in the world are in US

 EcoWatch -  Hundreds of wildfires have been burning in nearly all of Canada’s provinces for almost a month, the smoke from them drifting down into the midwestern and eastern United States. Major U.S. cities from Minneapolis to Charlotte have been affected by the eerie orange-tinged wildfire smoke, but last week four out of the five most polluted cities in the world — New York, Toronto, Montréal and Washington, DC — were in North America, according to Swiss technology company IQAir. “This is not something that we’re talking about future generations dealing with,” said New York Governor Kathy Hochul during a press conference last week, as CNBC reported. “We are truly the first generation to feel the real effects of climate change.”
