According to Tanja Mihalic, tourism theory has recognised the fundamental importanceof environmental quality for ensuring the future existence of most types of tourist destinations. Tourism managers have been willing to incorporate environmental measures into current management strategies and methods if they resulted in lower costs and/or higher revenues and profits (Stabler & Goodal, 1997, p. 19).Increasing environmental consciousness, tourist demand for better quality and the increased competition among destinations have changed the situation; environmental quality has become a current issue. Environmental quality of a destination is a prevailing issue in making travel related decision; it is a competitiveness factor among different tourist destinations with varying environmental quality. In many cases, environmental objectives and practice must be incorporated into the current attitudes management strategies and methods in order to stay competitive on the tourist market, e.g. in order to prevent a decrease in sales and prices, revenues and profits. The environmental debate in tourism recognises the(negative) impacts of the travel and tourism industry on the environment. Therefore, many environmental projects that minimise those impacts have been developed and marketed under the name of sustainability, ecotourism and other green brands and trademarks. In practice,much less attention has been devoted to the problem that other industries can erode the quality of the environmentthat attract visitors. Consideration of overall environmental quality includes not only control over the environmental impacts of the travel and tourism industry,but also minimises all kinds of environmental problems and includes investments in environmental protection and reinstation of already degraded environment.
