My dear reader surely knows that dinosaurs disappeared from Earth at the end of the Cretaceous period, after which the Cenozoic and subsequently the Quaternary period began. The last epoch of the Quaternary is the Holocene, which is officially ongoing in our time.
However, many researchers would like to name a new geological era for the time dominated by humanity. This era has been proposed to be called the Anthropocene. There has been some disagreement about when exactly this era began, although it is generally thought to represent the time when the cumulative impact of human activity began to significantly affect Earth's systems.
The problem lies specifically in the fact that the spatial and temporal variations of human impact are quite significant. That is why it was interesting to read an article by the Japanese researcher Michinobu Kuwae and colleagues, published in the Proceedings of the National Academy of Sciences of the USA, in which they compiled data on human impacts from 137 locations around the world over the past 7,700 years.
The researchers identified three periods during which human influence increased significantly. The first period occurred between 1855 and 1890, when significant changes related to the Industrial Revolution took place, such as increases in soil lead concentrations and shifts in the nutrient balances of lakes.
Between 1909 and 1944, changes were observed in pollen compositions, increases in black carbon concentrations, and widespread changes in stable isotopes. The third shift identified by the researchers occurred between 1948 and 1953, which saw a significant increase in organic pollutants and microplastics, as well as the emergence of plutonium and modern carbon-14 from nuclear explosions.
According to the researchers, the period between 1948 and 1953 represents the most significant global increase in human impact, leading to rapid changes in natural systems and important geochemical indicators. Therefore, they propose that the beginning of the Anthropocene should be placed in 1952.
I myself support this year, as many other significant events happened then beyond those mentioned in the study. I am, of course, referring to the fact that the Helsinki Olympics were held that year, and Finnish beauty, Armi Kuusela, was crowned Miss Universe.
Additionally, the beginning of the Anthropocene in 1952 is strongly supported by the fact that it was the year when Finland made its final war reparations payment to the Soviet Union, and Coca-Cola began to be imported and sold in the country. Unfortunately, Finland's first jet fighter was introduced only the following year, but it was still on January 22nd, so let's count that too as a sign of the beginning of a new era in world history.

If i remember right EU also set 1952 as the year which is the base mark for the European nature renewal . This is very unfortunate and also expected, because Germany destroyed it's forests on the 15th century Meanwhile, Finland with a lot of forests, begun some land clearing for the cultivation of crops. For this Finland will be punished.
