A large component of the commercial tourism industry relies on biodiversity as a primary attraction, either through scenery, national parks and reserves, or individual icon plant and animal species. Tourism and recreation produce a wide range of negative environmental impacts on biodiversity. A small number of commercial tourism operations, however, do make successful net positive contributions to conserving biodiversity. Ecotourism is widely promoted as a tool for community development in developing countries, and this can have either positive or negative local consequences on biodiversity. It also relies on long haul international travel, which contributes to climate change and associated negative impacts on biodiversity.
