Eco tourism, responsible tourism, and sustainable development have become prevalent concepts since the late 1980s, and eco-tourism has experienced arguably the fastest growth of all sub sectors in the tourism industry. The popularity represents a change in tourist perceptions, increased environmental awareness, and a desire to explore natural environments. Such changes have become a statement affirming one’s social identity, education, sophistication, and disposable income as they are about preserving the Amazon rainforest or the Caribbean coral reef for posterity.
With its great potential for environmental protection, the United Nations celebrated the International Year of Eco-tourism in 2002.
