The region is beautifully varied orographically, pedologically, climatically and of course hydrographically. The diversity of the physical conditions brought about a wonderful biological diversity, including naturally the algal flora. The worthiest natural inheritance, the biological diversity is subjected, as everywhere, to the human impact. The Some? collects all waters from its area, meanwhile it has to endure and transport a huge amount of garbage poured in it by nearly 3 million people and by factories. Here and there the river purifies itself for a while only to become more loaded again and brings this polluted water into the Tisza. ER -
