Ecotourism is a new trend in the tourism industry that focuses on questions of sustainability for the area being traveled to. The concept of ecotourism appeared in the 1950s, first being introduced in Africa with the legalization of hunting. However, it was not until the 1980s that ecotourism became widely accepted as travelers and host communities have become more educated and sensitive to the need to preserve the environment. In 2010, ecotourism represents the fastest growing subsector of the tourism industry.
