English: The fires are outlined in red. Most of the fires are concentrated in Bolivia, where the governments of two states had declared a state of emergency because of widespread fires three days earlier. Scores of fires also burn in Brazil, Paraguay, and Argentina. The fires cloak the heart of South America in gray-white smoke. Spreading north and south along the east side of the Andes Mountains, the smoke extends over the entire 2,500-kilometre length of the image. While some fires do occur naturally in Bolivia, most of these fires were probably set deliberately to clear land for crops or pasture.
