Study suggests hydroelectric dams causing greater impact on Amazon basin than thought

A team of researchers from the U.S. and multiple countries in South America has found that hydroelectric dams built in the Amazon river basin, which were built to meet the growing electricity demands in the region, are making more of an impact on the natural geography than previously thought. In their paper published on the open access site Science Advances, the group describes using data from satellites to learn more about the true impact of modern dam building.
