The green massifs of one or another functional purpose are an organic part of the city both within the boundaries of the building and beyond its borders.The history of the existence of cities goes back thousands of years In one of the oldest written monuments that have come down to us – “The Epic of the mythological hero Gilgemesh”, a peculiar plan of the territory of the city is presented. A part of the plan of the city of Nipuru, which existed in 1500 BC, has survived to our time. er A large part of it was occupied by parks and gardens.
Similar information is contained in the plans and descriptions of the cities of ancient India and ancient China.The role of green space in environmental protection• Features of urban environmental conditionsIn the cities, a specific and largely unfavorable for human activitylogical setting. The city’s air basin is constantly polluted by industrial waste, car exhaust gases and dust. If we compare the urban air with the air atmosphere of the suburban area, then it contains much less oxygen, there is an increased number of bacteria and microbes.The degree of atmospheric pollution depends on the following natural factors: wind direction and speed, air temperature and humidity, terrain relief and vegetation character.In large industrial cities in calm weather, so-called smog is often formed, or thick fog containing a high concentration of industrial emissions. Smog often causes serious diseases in people.

Solid particles of dust, being suspended and interacting with water vapor, which also saturates the atmosphere, are compounds that are harmful to the respiratory organs of a person. Strong dustiness of air reduces the illumination of the earth’s surface and thereby reduces the amount of ultraviolet rays of the sun useful for humans.The temperature regime in the city and the humidity of the urban air are subject to stronger fluctuations than in non-urban areas.
This often creates uncomfortable conditions for the urban population, especially on hot or cold days.The most serious negative factor for human life in urban environments is urban noise. Often the level of city noise is much higher than permissible norms, which adversely affects the health of people. Recently, the noise level in large cities has increased significantly, and the process of increasing noise continues. The rapid growth of cities is increasingly characterized by individual methods of construction and as a result of this, the massive construction of urban and suburban areas by typical houses and structures.
