Scientists have for the first time developed a method for assessing the impact of human presence on the planet on its condition.
Thus, it turned out that the Earth experienced its first man-made influence almost four thousand years ago. Already in those days, humanity began to leave an indelible mark.
These conclusions were reached after analyzing cores that were extracted from the bottom of lakes and swamps.
Until this time, it was believed that humanity began to leave its first indelible traces only a couple of centuries ago.
As an example, researchers cite periods when man learned to change the natural landscape, which significantly accelerated the achievements of the industrial revolution.
After obtaining samples of the solid layers of the Earth located at the bottom of lakes and swamps, it turned out that man intervened in the natural course of events at least four thousand years ago.
It has been noted that over the past 10 thousand years the Earth’s climate has been relatively stable.
After analyzing the cores, it was possible to track even the most minor changes to which humans contributed.
Scientists include the first periods of active destruction of wild forests in order to increase the areas intended for agriculture and livestock breeding.
Gradually, the weak influence turned into a real process of transformation, which finally changed the face of the planet.
