Currently, the Black Sea is an important part of the Atlantic Ocean and occupies an area of 420,325 km2.There are more than three thousand species of flora and fauna.A notable feature is the fact that all of the above diversity is found only at a depth of no more than 150 meters. Furthermore, falling below that mark, down to the very bottom, you can watch the complete absence of life forms with a few exceptions in the form of anaerobic bacteria.This is because the deep layers of water is a saturated solution of hydrogen sulphide.This destructive environment for all creatures, which is necessary for normal life of oxygen.
Black Sea: environmental problems
Like any other modern body of water, the sea is subject to the negative influence of anthropogenic factors.Every year hundreds of tons of hazardous substances discharged into his pool.Examples of these pollutants can be safely attributed all organic and mineral fertilizers, which generously fertilized the soil for better yield.It is they,
Environmental problems of the Black Sea are also determined by the following negative factors:
1. pollution of rivers flowing into it, waste rainwater.This entails not only a decrease in water transparency and flowering sea, but also the destruction of multicellular algae.
2. Contamination of water masses of oil.Such environmental problems of the Black Sea are most common in the western part of the area, where there are many ports and a large number of tanker shipments.The result is the death of many species of flora and fauna, a violation of their normal life, as well as the deterioration of the atmosphere due to evaporation of oil and its derivatives.
3. Contamination of water weight of the product of human activity.Such environmental problems of the Black Sea are the result of untreated and poorly treated sewage.The main burden falls on the north-western part of the region.There are the main fish spawning and breeding of different species of animals and birds.Another significant factor is the active building shoreline.As a result, the bottom surface of the Black Sea shelf is contaminated cement dust and residues of chemicals used in construction.
4. The negative factors may also include mass-fishing, which entails an inevitable and the global restructuring of marine ecosystems.
These are the main environmental problems of the Black Sea.
