and even more money is put into public relation campaigns to dilute the effects of criticism. Ecotourism channels resources away from other projects that could contribute more sustainable and realistic solutions to pressing social and environmental problems. "The money tourism can generate often ties parks and managements to eco-tourism" (Walpole et al. 2001). But there is a tension in this relationship because ecotourism often causes conflict and changes in land-use rights, fails to deliver promises of community-level benefits, damages environments, and has plenty of other social impacts. Indeed, many argue repeatedly that ecotourism is neither ecologically nor socially beneficial, yet it persists as a strategy for conservation and development (West, 2006). While several studies are being done on ways to improve the ecotourism structure, some argue that these examples provide rationale for stopping it altogether. However, there are some positive examples, among them the Kavango-Zambezi Transfrontier Conservation Area (KAZA) and the Virunga National Park, as jugded by WWF.[32]
