The United Nations World Tourism Organisation defines sustainable tourism as tourism that meets the needs of present tourists and host regions while protecting and enhancing opportunity for the future. Rather than being a type of product, it is an ethos that underpins all tourism activities. As such, it is integral to all aspects of tourism development and management rather than being an add-on component. The objective of sustainable tourism is to retain the economic and social advantages of tourism development while reducing or mitigating any undesirable impacts on the natural, historic, cultural or social environment. This is achieved by balancing the needs of tourists with those of the destination.

This definition matches perfectly with my feeling about tourism, in fact I work with some local, national and international organizations to develop a sustainable tourism here in Sardinia. I run courses of sustainable tourism for future operators.
