Satellite image shows fires (red dots) in southern Mexico, the Yucatan Peninsula, and Central America. From space, we've learned how common fires are around the world; about 90 percent are started by people. Fires may be a cheap way to prepare ground for planting, but burning a forest may set in on the road to desertification. Each year, people burn 750,000 to 8.2 million square kilometers of forest and grassland. As global warming proceeds, experts expect more fires. Photo from NASA Earth Observatory.
