Топик: Ecological problems in big cities, particular in Moscow. How can a contradiction between the technological progress and ecology be solved from my point of view?

2 Condition of flora and fauna.

A major component of urban terrain is the green massive (parks, urban forests and gardens), birds and animals inhabiting them. The greenery as well as the environmental system, provide comfort of living conditions for people in the city, adjusts to definite limits the gas composition of air and the degree of its pollution, climatic characteristics of urban territories, reduces the influence of noise factor and is a source of aesthetic perception.

Urban forests .

In the territory of Moscow there are not less than 36 wood missives. The largest woods massive of Moscow are Лосиный остров – in the city limits, Узкое and Измайлово . In old part of the city, within the boundaries of the Moscow Circular rail road, kept only two relevantly large woods massive: Сокольники and Останкино . The condition of forests as a whole can be described as loosened, that first of all determined by the site of the city limits and, accordingly, level of techno genetic loads.

Kept within the Moscow boundary other natural components (moors and rivers) are also in a bad condition, as well as forests they have undergone definite changes as a result of effect of the complex of anthropogenic factors and have lost those or divers qualities and properties, characteristic for natural eco system. These natural components more than woods are subjecting to threat to a full degradation because of their unattended development.

The city of Moscow includes green plantations parks (urban specialized), districts and children’s parks, squares and boulevard. The gardening of the streets takes the special place in improvement of an ecological condition of the city. The green plantations should execute one more function protection of terrains of a housing estate against a transport noise.

Fauna .

Since 1961 from a structure of a fauna of Moscow 23 kinds have vanished, first of all, by availability in borders of the city large forests and park of missives, bound with forests and parks by a protective belt.

Thermal pollution .

The analysis of thermal anomalies has shown, that the areas with positive highly and medium contrast by thermal anomalies (temperature rise above background more than 10ºC) are connected to industrial objects and intensive thermal outflow from underground of the water carrying communications.

Out come of outflow of ardent water from underground water carryings of the communications, in particular, is the change of a temperature schedule of underground waters.
