ethical consideration.
even if we learn how to reproduce an example of an extinct species, that individual could never have a normal life.
it is natural environment is most likely gone and it would have no parents to show it how to be have as a member of it's species.
So the animal would remain a curiosity and probably live out it's life in a zoo.
people question whether it would be ethical to revive one of nature's creatures for such a purpose.
only time will tell if scientists manage to carry out their ambitious plans.
even if they manage to overcome the scientific problem, they may face opposition from government or society.
some even feel it might be more worthwhile for us to focus our efforts on conservation and take care of existing species
so they don't also go the way of the woolly mammoth
