An ecosystem metaphor is often used to describe an industry as a whole, like a cluster, but having a more “lively” aspect. Montreal’s videogame industry promoters I met while doing my master thesis used the expression to describe the industry’s nature nowadays. It carries a strong living aspect as all parts make a whole organism, appearing to be one of the most valued industry in Montreal. However, as I argued in my master thesis: «We should not limit the ecosystem metaphor to its vivacity; ecosystem can easily be unbalanced and even destroyed by an external change.» (Pineault, 2014: 69) Anthropology’s Functionalists made an extensive use of the organic analogy in their attempts to explain culture and critics have showed its limit. In this short article, I would like to explain why we must be cautious about using the ecosystem to describe an industrial or creative cluster.
