Slum Tours: Ecotourism or Exploitation? In Kenya's capital, one of the most lucrative -- and controversial -- effects of ecotourism has been the proliferation of tours through Kibera slum, home to more than 1 million people, almost a third of Nairobi's population.
The purpose of this paper is to explore these questions, to go below the surface and take a deeper look at ecotourism in Costa Rica, thereby facilitating a clearer understanding of the complexity of this phenomenon. Specifically, this paper examines ecotourisms impact on the economy and environment of the country. For that purpose, tourism, environmental, and economic transitions are critically researched, with an emphasis on how these transitions interrelate.
