What environmental pollution do you know?
Environmental pollution is an undesirable change in its properties, which leads or can lead to harmful effects on humans or natural complexes. The most famous type of pollution is chemical (the release of harmful substances and compounds into the environment), but such types of pollution as radioactive, thermal (uncontrolled release of heat into the environment can lead to global changes in nature’s climate) pose a no lesser potential threat. Basically, environmental pollution is associated with human activities (anthropogenic environmental pollution), however, pollution is possible as a result of natural phenomena, such as volcanic eruptions, earthquakes, meteorites, etc. All the Earth’s shells are polluted.
The lithosphere (as well as the soil cover) is contaminated as a result of the ingress of heavy metal compounds, fertilizers, and pesticides. Only garbage from big cities annually takes out up to 12 billion tons. Mining leads to the destruction of natural soil cover in vast areas.
The hydrosphere is polluted by the effluents of industrial enterprises (especially chemical and metallurgical), effluents from fields and livestock farms, domestic wastewater from cities. Oil pollution is especially dangerous – up to 15 million tons of oil and oil products fall into the waters of the World Ocean every year.
The atmosphere is polluted mainly as a result of the annual burning of a huge amount of mineral fuel, emissions from the metallurgical and chemical industries. The main pollutants are carbon dioxide, oxides of sulfur, nitrogen, radioactive compounds.
As a result of growing environmental pollution, many environmental problems arise, both at the local and regional levels (in large industrial areas and urban agglomerations), and at the global level (global climate warming, reduction of the ozone layer of the atmosphere, depletion of natural resources).
The main ways to solve environmental problems can be not only the construction of various wastewater treatment plants and devices, but also the introduction of new low-waste technologies, re-profiling, transferring them to a new place in order to reduce the “concentration” of pressure on nature.
