Tens of millions of people in Canada and the United States have been living an apocalyptic scenario since yesterday. The blue sky of the past few days has turned into a kind of grayish or even reddish haze.
The sun has disappeared. In cities like New York it is impossible to see the other side of the famous bridges that cross the East River because visibility has been reduced to 500 meters. In New York and Washington, authorities have asked people to try to spend as little time as possible on the street, and when they do, wear masks.
