Ecotourism, or 'green tourism' is environmentally friendly tourism.
Ecotourism caters for a small but growing niche market of environmentally aware tourists - it is the fastest expanding tourism sector.
Inevitably, these holidays cost more, which means they only attract people with enough money. Less well-off people may understand the need for sustainable tourism, but not afford it.
Ecotourism is sustainable, has some educational or interpretive value and is nature based.
Ecotourist facilities and activities should not cause an environment to radically change.
Waster is recycled, and waste is treated through reverse osmosis.
Ecotourists prefer small-scale accommodation in lodges that may not even have electricity.
Local people are guides as their knowledge and experience is seen to be more valuable.
