From the Amazon Rainforest of Brazil, to the Pantanal Wetlands, to the Gran Chanco plains of Paraguay and Argentina, hundreds of fires were burning across South America on 18 August 2005. This image of the heart of the continent was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASAs Terra satellite shows fires marked in red and a cloud of smoke hanging over a large swath of the heart of the continent.

Along the southeastern margin of the Amazon Rainforest, people are creating islands of rainforest surrounded by farms and ranches. Fire is a common land-clearing or land-management tool in the region, and numerous fires were detected by MODIS in the image and are marked with red dots.
