The social priorities of literature are the tribune of environmental idiology. Today, in the Mongolian literature, the direction of ecocriticism has been established. This article makes an analysis in traditional Mongolian poetry and modern poetry on the topic of nature conservation and ecology. In Mongolian folklore praise the purity of nature and the motherland. His idol of pure nature is praise and praise. But each species has its own color. The topic of nature protection in Mongolian folklore (Orthodoxy, Magtaal-praise, Tuul-epic, du-folk songs and myth) is that a person should not control and control nature but understand and convert to nature as a living creature; means that people will have a natural relationship, a balanced and safe life. Probably, there is not a single poet of Mongolia who does not address the topic of “man and nature”. Each in its own way perceives nature, and each in its own way revealing to the reader the world of nature and himself in this world. The space of the “Mongolian spirit” created by the poet is filled with natural landscapes, people, and historical memory. His ancestors and descendants, the dead and living, are called upon to preserve this space and believing that nature and civilization can exist in equal harmony, he would like to reconcile them among themselves. Therefore, the poems of Mongolian poets writing about nature sound like a distress signal, like a cry for help to nature. This is a feature. That is why Mongolian writers have initiated environmental protection measures. They stopped the construction of a chemical plant on Lake Hubsgul. The lake is the main freshwater reservoir in the world. Mongolian writers also warned that the pine forest “Tuzin Nars” was destroyed in nature every year billions of tons of waste. With such an attitude of man to nature on Earth there will soon be nothing left. There are examples of the writer C. Galsan, who planted 360 thousand trees. In this article we propose that we do not limit the observation and conclusions about the mastery of writers to the nature of the writings, but take into account personal, mental and social changes in the environment.

AbstractUst’-Polui is one of the most extensively studied archaeological sites in the western Siberian Arctic. New radiocarbon (14C) dates for charcoal, faunal remains, bark, hide, and human bone from this site are presented. When modeled, the charcoal dates span from ~260 BC to 140 AD, overlapping with the dendrochronology dates from the site. These dates also overlap with the expected age of the site based on artefact typology. 14C dates on reindeer bone have a slightly younger modeled age range, from ~110 BC to 350 AD. In contrast, dates on the site’s numerous dog remains, and on human and fish bone, all predate these modeled age ranges by over 500 years, despite being from the same deposits. Several sets of paired dates demonstrate significant age differences. Bone dates with lower δ13C values tend to be over 500 years older than those with higher δ13C values. Stable isotope data for the humans, dogs, and other faunal remains are also presented. These data suggest the dogs and the humans were regularly consuming freshwater fish. The dogs were probably fed fish by their human counterparts. Overall, the dog and human dietary patterns at Ust’-Polui created 14C dates biased with major freshwater reservoir effects.

ABSTRACTRecent studies have shown that faunal assemblages from Mesolithic sites in inland Northern Europe contain more fish remains than previously thought, but the archaeological and archaeozoological record does not reveal the dietary importance of aquatic species to hunter-gatherer-fishers, even at a societal level. For example, the function of bone points, as hunting weapons or fishing equipment, has long been debated. Moreover, traditional methods provide no indication of variable subsistence practices within a population. For these reasons, paleodietary studies using stable isotope analyses of human remains have become routine. We present radiocarbon (14C) and stable isotope data from nine prehistoric human bones from the Early Mesolithic-Early Neolithic site of Friesack 4, and isotopic data for local terrestrial mammals (elk, red deer, roe deer, wild boar, aurochs, beaver) and freshwater fish (European eel, European perch). The reference data allow individual paleodiets to be reconstructed. Using paleodiet estimates of fish consumption, and modern values for local freshwater reservoir effects, we also calibrate human 14C ages taking into account dietary reservoir effects. Although the number of individuals is small, it is possible to infer a decline in the dietary importance of fish from the Preboreal to the Boreal Mesolithic, and an increase in aquatic resource consumption in the Early Neolithic.
