Abstract
The travel industry is the first industry on earth with 1.6 billion tourists as estimated in 2020. Tourism presents at the same time opportunities and threats for biodiversity conservation. That is why it is important to promote new forms of tourism and to apply new principles for the actors of tourism as well as tourists. According to Goetschmann, tourism is 'the activity of travelling for pleasure.' This definition gives us the reason for travelling which is mainly pleasure. Tourism is evolving because our century is not any more a quantitative one, which means that mass tourism will not exist anymore. We need today, to protect our environment and cultures and the tourists are definitely aware of this problem. That is why sustainable tourism is an emergent market today.
