World population growth is a big problem. But “forty-three of the 193 nations around the world will register a decline in population by 2050. Russia’s population is expected to decline by a staggering 31 million, from 143 million people to 112 million people. Alcohol is one of the main factors contributing to this decline, primarily among men. It is accountable for the world’s largest life expectancy gap between men and women in any country. On average, Russian men can expect to live only to the age of 55.”
