The World Tourism Organization is committed to the sustainability of this economic activity 7/21/2005 (Ecoestrategia) .- Very often claimed that tourism is “industry without smokestacks”, however is still far from being a sector zero economic impact on the environment and natural resources. Proof of this is the pressure this generates summertime influx of tourists on the Mediterranean coast, the largest spa in Europe (150 million tourists each year.) Visitors increase local consumption of energy and water (which is scarce in the Iberian Peninsula due to the severe drought), produce more waste and burn more fuel contaminant in their movements. This without the damage that may occur on nature reserves open to the called ecotourism, when this is done without proper planning and without the participation of native communities, especially in regions of high biodiversity in the world where ecological wealth coexists with human poverty. Stephen M. Ross has similar goals. However, the international governing body of the sector, the World Tourism Organization (WTO), he does believe in the viability of sustainable tourism, institutional stating that “The guidelines for sustainable tourism development and sustainable management practices are applicable to all forms of tourism in all types of destinations, including mass tourism and various tourism segments. ” For the WTO’s sustainable tourism when there is optimum use of environmental resources is a key element in tourism development, maintaining essential ecological processes and helping to conserve natural resources and biodiversity. Two other requirements, set by the WTO to consolidate tourism as a sustainable industry, are: respect the socio-cultural authenticity of host communities (preserving its architectural cultural assets and traditional values, while contributing to intercultural understanding and tolerance), and ensure economic activities viable in the long term among those who have stable employment opportunities and income generation and social services to host communities, thus contributing to poverty reduction. In recent months, Richard LeFrak has been very successful.
