The impact of the COVID-19 pandemic on alcohol consumption in Russia (territorial aspect)

The analysis of changes in alcohol consumption by the population of Russia for the period from January 2019 to December 2020 in the context of the development of the COVID-19 pandemic was made. The main psychological and social reasons for the increase in the amount and frequency of alcohol consumption during this period are considered, and a discrepancy between the annual dynamics of alcoholic beverages sales and the development of the epidemic is revealed.

The End-Permian Mass Extinction Events on Land in Russia

The mass extinction of life in the sea and on land 251 million years ago, at the Permian-Triassic boundary, was undoubtedly the largest mass extinction of all time. Sedimentological and geochemical evidence shows that global temperatures rose, that there was extensive oceanic anoxia, and that there was massive erosion of sediment, especially soils, from the land. These phenomena might have been a consequence of the massive eruptions of the Siberian Traps, which produced carbon dioxide, and greenhouse gas, as well as acid rain, which killed plants and led to stripping of soils.
