Definition request

  1. Apr 13, 2005 #1
    I am looking for a definition. I know the word but I forgot it. This topic came up when a friend of mine were talking today.
    What is it called when an outsider comes into a primitive society (or observing a pride of lions, ect) and the presence of the observers contaminates the environment they are trying to capture "naturally"?
    Thanks Rad
