The consideration of the bill about organization of cascade hydroelectric power stations on the mainstream of the river Multa was adopted in 2010. Environmentalists predict the terrible consequences to both the river and its basin, and, ultimately, it will come to total destruction of untouched nature for the sake of human greed. Currently, activists collected signatures to assign status of reserved area for the valley of Multa River. The confrontation result is not yet clear, but we hope the River will be able to safely carry its crystal water, as if the memory of the fact that humanity has almost lost.
