Abstract
While having a look through pages of the press, one becomes aware, for so many times, of the incontestable fact that in certain regions of the Danube there are attested damages caused by the human harmful interference in the environment. It consists in the overexploitation of fish resources, in illegal hunting, etc. Another challenge consists as well in the climate changes that constitute a threat to thousands of species of plants and animals. There raises involuntary the question: what measures is it necessary to be taken in order to protect the Danube that has had a lot of sufference from the end of the last century up to nowadays after having undergone the human interference? That is, for exemple, alongside the river there have been built hydroelectric dams, dikes, turbines etc. So the problem of the environment protection has been concerning as well the writers from all periods of time.
