Since the 1990s ecotourism has exploded, especially in developing nations in Latin America, Africa and Asia where there are rain forests. These nations have established numerous nature preserves and national parks, and their outstanding natural resources and unique cultures have attracted growing numbers of tourists from the developed world.
