What do you know about Ecotourism?

ecotourism
Am asked:

Do you think videos such as this http://www.islandreefjob.com/applicants/watch/HWgngkvYHK8 not only serve to get the best candidate a job position with Queensland Tourism, but also serves to promote ecotrourism at no cost to Queensland Tourism? Other then this video stating that tourism can be equated to environmentalism, do you think most video applications will be about Ecotourism? If so how much do you know about “Ecotourism” and how do you think it’ll serve Australia in this case?
