People tend to define things in terms that are beneficial to themselves, hence the variety of definitions. There are however several workable definitions currently in wide use. Most serious studies of ecotourism including several University programs now use this as the working definition. These destinations are often remote areas, whether inhabited or uninhabited, and are usually under some kind of environmental protection at the national, international, communal or private level.
Tourism causes damage.
Ecotourism strives to minimize the adverse affects of hotels, trails, and other infrastructure by using either recycled materials or plentyfully available local building materials, renewable sources of energy, recycling and safe disposal of waste and garbage, and environmentally and culturally sensitive architectural design. Minimization of impact also requires that the numbers and mode of behavior of tourists be regulated to ensure limited damage to the ecosystem. Ecotourism means education, for both tourists and residents of nearby communities. Well before departure tour operators should supply travelers with reading material about the country, environment and local people, as well as a code of conduct for both the traveler and the industry itself. Essential to good ecotourism are well-trained, multilingual naturalist guides with skills in natural and cultural history, environmental interpretation, ethical principles and effective communication.
