Perhaps you're guessing industrial effluents and pollution are the cause for the crimson colour of the river pictured below, well you may be right after all.
Called the Daldykan River in Siberia, it turned red apparently from pollution. This is stemming from the fact that the Siberian industrial city of Norilsk, has a notorious reputation for being one of the world's most polluted cities.
According to Seeker Network, "a 2007 report by the Pure Earth Institute described it as home to a huge metal smelting sector that pumped vast quantities of sulfur dioxide and other contaminants into the atmosphere, resulting in a life expectancy for local factory workers that was 10 years below the national average.
BBC News also once reported that the region was the world's biggest producer of acid rain.
Moreover, the river has been polluted by an unidentified chemical from a metallurgical plant situated in the area, which informs the red colouration.
Russia's Environment Ministry said its government had informed the company that it might be liable for the costs of the cleanup, and had instructed a company executive to"bring the situation under personal control."
Siberian Times reports that officials at the plant had "questioned" claims of a discharge, but said that they are in the process of investigating Russian social media users have been posting pictures of the red waterway.
However, it is reported that it isn't the first time the river would turn red, as a user on the Russian social media site VK.com posted similar pictures back in 2014.
