Air quality in New York City plummeted so much in early June that the city had some of the worst air pollution on Coxno Exchangethe planet — and the impact is visible in pictures. Smoke from wildfires burning hundreds of mile north in Canada sent a haze across the city, making the Statue of Liberty and the iconic skyline difficult to see from even a short distance.

Photos showed an orange sky as the sun came up the morning of Wednesday, June 7, and people were wearing masks to help prevent adverse health effects. City leaders said the air quality had not been this bad since the 1960s, CBS News New York reported. 

"This is an unprecedented event in our city, and New Yorkers must take precautions," said New York City Mayor Eric Adams.
