The Murzinka River turned red in St. Petersburg, Russia on May 12, 2018. The strange phenomenon was shot from a residential house. You clearly see that the river has turned brown-red:
According to social network discussions, the river constantly changes color, “like a chameleon, from poisonous-yellow to blood-red, it flows into the Neva.”
“Murzinka River: today it is red and foams, tomorrow it has a deep greenish to black color” says a publication of one of the users of the social network.
I would not eat a fish coming from this highly polluted river (… And neither from the NEVA actually). Pollution is all around. Let’s try to fight against it!
