The Republic of Botswana made a strategic decision a decade or two ago to get into the eco-tourism business, however they only accept tourism on their own terms. They recognized that their ecology could only support a limited number of travel operations without sustaining damage, so they decided to go for the "high end" safari market.  I applaud them on this decision.  Their continuing efforts to keep control of tourism and promote responsible tour operators appears to ensure eco-tourism is a significant component of any development plan proposed for a particular area by a tour operator.  I find it reassuring that even the camp staff who I had contact with all understood the connection between low impact operations and a continuing healthy tourism industry.
