If Russia continues to make progress in reducing mortality and if not increasingfertility then at least preventing it from declining, it will likely be able to maintain its current population.
And while the extra water from the melting glacier may be increasing the fertility of adjacent lowland areas in the short-term, water supplies would become critically low if it disappears.
