Why are rivers in Alaska turning orange?

Dozens of rivers and streams in the US state of Alaska are turning rusty orange. Scientists believe that permafrost, or frozen land, is what is causing the hue change. They claim that when the environment warmed, minerals kept in permafrost were released into glistening, clean water. Researchers are also concerned, as this change could threaten fisheries and drinking water quality
