Dwindled Giant

South America’s once- mighty Paraná River is now at its lowest level since 1941, causing thousands of acres of wetlands to dry up as well as threatening public water supplies and the livelihoods of fishermen and farmers.

Experts say they don’t know if this is part of a natural cycle or climate change. But there has been a three-year period of below-normal rainfall at the river’s source in southern Brazil. Low water levels have also created a 50% drop in hydroelectric power at generating plants along the Argentina-Paraguay border.
