WORLDCHANGING:

"The Culture of Extinction: Tattoos for Dodoes"

On page 493 of the Worldchanging book I found an interesting suggestion concerning a method to spread awareness on animal extinction. The suggestion made was that people "adopt" an extinct species, the price of "membership" being a tattoo of that species on a visible part of the body. The thought process behind this was to create a tangible voice for these animals that are no longer around. By tattooing this animal on your body and "adopting" to be its voice, you then become a vessel to spread the legacy of this animal as well as to make people aware of the seriousness of animal extinction.
Although this suggestion was intended to make something taboo more personable, I really think this is just silly. To me, tattoos are something that should be personal and really sacred to the person who has them.
Do you think this is a good way to spread awareness on the topic of extinction? Furthermore, do you think tattoos have lost their sacred quality? Is it just something to do and be "cool" now?
