Using the idea of sustainability in terms of not having any alternative forms of modern town planning gives a false image of the only chance humanity has to overcome the problem of urban withering. The paper in to show the idea of urban biom as a form of redeveloping cities in non- formal and non- technical way, which is nowadays associated mostly with the idea of sustainability – energy and water efficiency, green technologies of the future and so on. Biom is a new form of identifying green areas, not only as passive, but mostly active form of urban development basing not only on flora but also urban fauna, differing and depending on geographic region in which the city is located.By leaving the idea of programmed zoning of eco- cities a new kind of urban utility zoning basing on the idea of biom is to be created. The beginning of change can be defined by technological, cultural, industrial, communication progress, which "liberated" large city areas or supported them for the inhabitants. A significant reduction of restricted zone area, excluded from use, but also occurring rapidly transformations of socio - political form, which are often the next stage of the industrial revolution resulted in the need to formulate a new development policy of those empty spaces that remain in the place of former functions. Simultaneously one can observe differences in the modern approach towards animals as a part of urban nature and the independence of modern man from immediate animal work, but also lack of having daily contact with them in various forms of humans' separation from nature.
