I disagree with this argument. For keeping extant species alive, we are
trying to maintain existing ecosystems. Bringing back extinct species
would be to modify ecosystems. Understandably, there is a fine line
as to recently lost species.
As far as bringing back a mammoth is concerned, I believe the goal there
is different. I can't imagine that anyone really expects to restore a
species in this manner, I doubt they will succeed any further than
creating an interesting zoo animal. From a scientific perspective, I
find it very intriguing, and would be dying to follow any results of the
work. If nothing else, it will give us an idea of how well we can read
the fossil record, at least the recent fossil record.
Does anyone know who is pursuing this venture? Is it purely scientific
or is some economic enterest involved?
