Canadian wildfires prompt air-quality alerts across five US states

Smoke from wildfires in Canada has triggered air-quality alerts across the US as multiple states brace for poor air quality. At least 25,000 residents in three Canadian provinces have been evacuated due to the fires, which are burning rapidly, fueled by both human activity and natural causes. In response, New York issued an air-quality advisory affecting parts of the state, while New Jersey declared a code orange alert. Iowa issued a statewide warning, and Maine announced an action day for dealing with thick smoke.
