The quality of the environment, both natural and man-made, is essential to tourism. However, tourism's relationship with the environment is complex. It involves many activities that can have adverse environmental effects.
Many of these impacts are linked with the construction of general infrastructure such as roads and airports, and of tourism facilities, including resorts, hotels, restaurants, shops, golf courses and marinas.
The negative impacts of tourism development can gradually destroy the environmental resources on which it depends. Source: United Nations Environment Programme (UNEP), 2001
