The international group of scientists calculated the lump of the artificial constructions created by the person.
The technosphere represents set of objects which are made and used by the person. Buildings, roads, tools, power stations, electronic devices, in particular, concern to them. The managed woods, agricultural holdings and waste also enter a technosphere. At the same time, without watching prevalence of such objects, their general size was unknown.
In new work scientists from Leicester University and other organizations calculated the space which is occupied by the territories transformed by the person. Then they estimated density and thickness of objects, using data of archaeological and geophysical surveys. The amount of constructions wasn’t considered as it required creation of detailed three-dimensional maps for each site.
The analysis showed that the mass of a technosphere reaches 30 trillion tons that on 29,9 trillion tons it is more, than all adult population of Earth. According to authors, assessment is simplified, but isn’t deprived of a sense. So, if to count the technosphere layer thickness which contains in itself(himself) 27,7 trillion tons of material on square meter of the planet about 50 kilograms of products of a technosphere is necessary.
