Recent evidence indicates the presence of diverse eukaryotic organisms, including both protozoans and metazoans, in these extreme environments. These findings challenge long-held notions about the biological limitations of such habitats and highlight the adaptability of life, suggesting that similar ecosystems worldwide may also harbor undiscovered biodiversity.
This paper reflects the importance of cooperation and treaties of good proximity in order to solve the environmental problems occurred in the Black Sea. Ten years ago, an accident discharged a major amount of oil in the coastal area of Turkey.
The attempts of remediation changed the local water chemical composition. This led to the emergence and overgrowth of some invasive species. Many European studies and specially created commissions analyze the possible solutions to solve the problem affecting Romania, Bulgaria, Turkey, Ukraine, and Russian seaside.
The present paper structured into five parts presents some aspects registered along the Black Sea coastal shore into the south part of Romania, near the Bulgarian border. There are mentioned some major physical modifications, appeared in the last decade, due to uncontrolled erosion and several collapses of the cliffs.
Further, there are presented some measurements and samples collected, during three consecutive years. The Black Sea represents a key interface between the European Union and the former Soviet countries and a direct connection by the Turkish Channel with the Mediterranean Sea. Thus, a healthy environment of the Black Sea represents a priority for the entire Europe. A special paragraph shows the endangered species because of the different modifications of the water quality and the new environmental conditions.
