Russia is home to the largest number of reindeer in the world, but soon it may decrease considerably. Why are environmentalists so concerned? If there is no deer, there is no Dolgans, Evenks and other peoples. Indigenous and small-numbered peoples of the North make one with the environment because of their lifestyle. The loss of this element will destroy the traditional lifestyle of many indigenous and small-numbered peoples of the North, which has developed for centuries in the North of Yakutia.
