It flows into the Black Sea through the Danube Delta, the River is a river seen through 10 countries (Austria, Bulgaria, Croatia, Germany, Hungary, Moldova, Slovakia, Romania, Ukraine and Serbia), and during or receives numerous tributaries. It is the only river in Europe whose ecosystem is threatened due to human interventions harm reconciliation projects, drainage, dams, sewage and without a thorough and well documented, the infrastructure works on the Danube should be applied immediately to eliminate the existing thresholds and improve navigation. Natural Islands over the Danube should be protected. Inter-island water areas are important areas for fish (spawning area for sturgeon). River care requires careful maintenance of fisheries resources correctly. Water quality is important for obtaining drinking water of more than 20mil people in the Danube basin. Continued destruction of wetlands leads to major problems in terms of flood management and reduce the amount of nutrients that naturally filter avoiding additional costs for wastewater treatment. Affected by global warming and overfishing are massive damming the Danube to lose with little incutul fauna and flora. International Commission for the Protection of the Danube River Vienna-based planning a careful evaluation of the Danube water quality by:

-Protecting the Black Sea against pollution;

-Protection against river pollution;

-Maintenance of normal flora and fauna and implementation by all countries share a liberal flood maps for the whole course of the Danube.

The importance of hydropower, navigation and fish an important source of water for agriculture, industry and population. Delta an exotic land with many trees and plants, species of mollusks insects, reptiles, amphibians, birds and mammals are declared monuments of nature and unique species. Important source of food as well as important scientific and economic resource. The economic man pushed the Danube to dig its fauna and flora destroying civilization through tourism and mining have destroyed the world built in the image of heaven that will go out soon.
