Do you think it worth the money and effort to develop an Elephant dictionary?

Last night on 60 minutes they had a story about a lady named, Andrea Turkalo and her observations of elephant sounds, as she has spent 20 years of her life studying the sounds of Elephants in Africa. Ms Turkalo believes elephants actually talk too each other. One part of the story was very compeling. A baby elephant had died from natural causes. The elephants made a funeral procession and they went by the baby elephant one by one making sounds as to express their feelings about the death of the baby elephant.

Ms Turkalo and her Cornell University associates are developing an elephant dictionary based on observations and sounds of elephants . Ms Turkalo stated it will take 15 more years to develop this dictionary.

My question, do you see any practical application to developing an elephant dictionary?
