Seven rivers in the north of the Urals carry death to people, animals and forests. Who poisoned them? Photo: Ivan Zhilin / "New Gazeta" Ivdel and Severouralsk are the alarm. Rivers in the vicinity of these small Ural cities changed color. Instead of transparent they became green, and their bottom was covered with thick white mucus. The forest growing along Olkhovka, Tamsher, Banna, Taltius, Black, Ivdel and Shegultan, died. On the shores, the locals began to find the corpses of animals.
