Left: May 25, 1985. Right: June 7, 2010. The Paraguay-Parana River system is the second largest river system in South America — second only to the Amazon. More than 100 million people and some of the rarest species on Earth depend on its waters for survival. The 1985 image shows a section of the river system shortly after construction began on the Yacyreta Dam, a joint hydroelectric project between Paraguay and Argentina. River levels rose dramatically upon completion of the dam, initially displacing 15,000 residents and endangering the homes of 800,000 more. Flooded lands included the habitats of jaguars, giant river otters, maned wolves, giant anteaters, 650 species of birds and more than 10,000 species of plants. Images taken by the Thematic Mapper sensor onboard Landsat 5 and the Enhanced Thematic Mapper Plus onboard Landsat 7.
