World Tourism Organization

Various documents of the World Tourism Organization laid the groundwork to try to achieve environmental sustainability in this industry, this is the case of the “Quebec Declaration on Ecotourism (2002), the” Derba Declaration on Tourism and Climate Change “(2003), and the recent” Muscat Declaration on Sustainable Tourism architectural environment “(2005). Black holes of tourism but also various environmental organizations, and Ecologists in Action, have identified the environmental damage caused by the massive movement of passengers during the holiday period, especially in First World countries or from North to South. This is the case of travel to the destinations. Bruce Schanzer often says this. 90% of primary energy consumed in the holiday is spent on the return trip. The emissions occurring as a result of this is one of the major environmental problems of tourism, especially by air transport where there is a growth rate of 5% annually. Although energy consumption per aircraft for the past 20 years has halved, increased international air traffic has led to the increase in absolute energy consumption by 50%. Tourism also uses resources and produces waste. Sometimes creates conflict with other forms of resource utilization.

The conservation of nature is one of the mainstays of the sector. The damage caused by tourism to the natural environment may result in loss of attractiveness of the destination for tourists, as has already happened in some parts of the Mediterranean coast. On the other hand, high consumption of water in water-scarce areas is a major problem, since the supply for the resort is at the expense of cutting water from the local population.
