Multiple fires are visible in in this image of the Para and Mato Grosso states of Brazil. Many of these were most likely intentionally set in order to deforest the land. Deforestation is the removal of a forest or stand of trees where the land is thereafter converted to a nonforest use. Examples of deforestation include conversion of forestland to farms, ranches, or urban use. The herringbone-patterned tan lines cutting through the dark green of the Amazon Rainforest in the middle of the image are evidence of deforestation in the Brazilian state of Pará. The deforestation in Pará follows the Brazialian national motorway BR 163, passing by cities such as Novo Progresso. The lower half of the image shows the state of Mato Grosso.
