Human Impact on World's Rivers 'Threatens Water Security of 5 Billion'

"The world's rivers are so badly affected by human activity that the water security of almost 5 billion people, and the survival of thousands of aquatic species, are threatened, scientists warned.

The study, conducted by institutions across the globe, is the first to simultaneously look at all types of human intervention on freshwater – from dams and reservoirs to irrigation and pollution. It paints a devastating picture of a world whose rivers are in serious decline.

While developing countries are suffering from threats to both water security and biodiversity, particularly in Africa and central Asia, the authors were surprised by the level of threat posed to wildlife in rich countries."
