The article presents the main assumptions concerning the functioning of Natura 2000 sites in Europe, with particular emphasis on Polish regulations. These areas of high natural value directly influence the shape of nature conservation and the state of the climate. In this latter context, legal norms and legislators face the challenge of finding such a legal framework to prevent the progressive degradation of the climate. The functioning Natura 2000 sites in Poland as one of the forms of nature protection may be helpful in this respect, provided that the plans of protection tasks are adapted to the changing environmental conditions. ; W artykule przedstawiono główne założenia dotyczące funkcjonowania obszarów Natura 2000 w Europie, ze szczególnym uwzględnieniem regulacji polskich. Tereny te, cenne przyrodniczo, bezpośrednio wpływają na kształt ochrony przyrody oraz stan klimatu. W tym ostatnim kontekście przed normami prawnymi i legislatorami stają wyzwania znalezienia takich ram prawnych, aby zapobiec postępującemu degradowaniu klimatu. Funkcjonujące obszary Natura 2000 w Polsce jako jedna z form ochrony przyrody mogą w tym zakresie okazać się pomocne, o ile plany zadań ochronnych zostaną dostosowane do zmieniających się uwarunkowań środowiskowych.

This paper presents a possible application of fuzzy logic systems to control vehicles in computer games. A new architecture of a fuzzy logic system is here proposed: Hierarchical Fuzzy Controller, that is composed of several fuzzy controllers in their classic meaning. "Hierarchical" means that fuzzy sets produced as output of one of fuzzy controllers are then processed as input of another fuzzy controller. The use of such a controller significantly enhances the possibilities of computational intelligence methods in singleplayer games, i.e. where the enemy is controlled by an agent simulating real behaviour (movement, decisions, etc.). The proposal of an original architecture of Hierarchical Fuzzy Controller, built with fuzzy controllers (in the sense of Mamdani), and discussing advantages of using this architecture to control military vehicles in a 2D single-player game, in comparison to classic fuzzy controllers, are the main scope of the paper.
