Today tourism is an important component of development, not only in economic terms but also for knowledge and human welfare. Tourism today is an activity accessible to a growing number of people. The tourism industry has nevertheless given rise to some serious concerns, including social costs and ecological impacts. Many ancient local cultures have practically lost their identity. Their societies have oriented their economy only to this industry. Both the natural and cultural – rural or urban – landscapes have also paid a high price for certain forms of tourism. These problems will persist if the economic benefit is the only target, leading to economic gains that eventually become ruinous. It is also important to consider that visitors nowadays are increasingly demanding in cultural and environmental terms.
