The modern ratio of gases in the atmosphere of Earth is not something primitive. Its considerable, but extremely slow changes happened and before emergence of a technosphere. Only 100-150 years ago the person started introducing the defined amendments in natural tendencies of development of the atmosphere. Enormous reserves of air and the seeming boundlessness of the atmosphere generated conviction in inexhaustibility of the air basin. The modern amount of intervention of the person in atmospheric processes (withdrawal of gases, technical emissions, etc.) is measured by astronomical sizes. Natural and technogenic processes in the atmosphere become threateningly comparable.
The main pollutant of the seas which value quickly increases, oil is. This type of a pollutant gets to the sea in the different ways: during descent of water after washing of tanks from under oil, at crash of vessels, in particular oil-carriers, during the drilling of a seabed and accidents on sea oil fields, etc.
The industrial enterprises dumping thermal waste in the air or reservoirs releasing into the atmosphere liquid gaseous or firm (pollution pyleva, can change local climate. If air pollutions continue to grow, they will start affecting and global climate.
The atmosphere as natural system is essential for functioning of all live organisms occupying our planet. However human society, making deliberate and inadvertent impacts on the atmosphere, changes its properties in the adverse direction. These influences especially increased in present period.
Land, water and air transport, throwing out exhaust gases, dust and thermal waste, can also influence local climate. The continuous building weakening or stopping air circulation, and outflow of local congestions of cold air affects climate also. Pollution of the sea, for example, oil influences climate of extensive spaces.
It is necessary to understand change of its structure at intake of impurity of a natural or anthropogenous origin as pollution of the atmosphere. Eruptions of ashes and gases volcanoes, the forest and steppe fires sated with salts sea splashes and fogs, dust from bald-headed soils and thin sand of deserts, vegetable pollen, microorganisms, allocations of animals, and also space dust concern to the first.
