The smoke from unusually large number of fires in Brazil is causing breathing difficulties and concern among residents and authorities.
According to the article, the smoke has reached record levels and has affected air quality in several cities in Brazil, including Sao Paulo.
The smoke is causing a thick haze and reducing visibility, leading to the cancellation of flights.
The fires are mostly happening in the Amazon rainforest and are attributed to deforestation for agriculture and cattle ranching.
The situation has led to international concern and calls for action to protect the rainforest and combat climate change.
