“According to the non-governmental organization Heritage Watch, Angkor saw 7600 visitors in 1993; by 2006, the number was 1.6 million; by the time 2010 is up, the complex will likely draw 3 million. Tourists of course bring in money for the developing country, as well as help assure a certain degree of protection for cultural sites. But they also walk everywhere. They touch things.”
