Hi Onifire,
Only a financial value, like with Disneys Animal Kingdom. The Disney family would stand to gain an enormous amount of money if they can build a park exibiting extinct animals. Then the occational tourist can visit the park, see the extinct animal alive and walk away never take any interest in it again. What value can that have in a moral or ethical sense? If we don't care about the animal or its environment when it's alive, why try to pretend we care about them when they're extinct?
Jurassic Park the movie makes a good case study of the ethics or lack thereof of resurrecting exinct animals through cloning. This also is a good treatise on the unfortunate dilemna in which scientists and researchers are subject to the financial whims of for-profit finanicial institutions and corporations. Without money the world will not go round, even for science and medicine.
