De-extinction means an artificial restoration of an extinct species! Although it may seems a laudable goal from an environmental and scientific perspective, in reality there are many drawbacks and detractors to an experiment of this type.

Ricardo Garcia and Antoni Margalida, scientists from the Pyrenean Institute of Ecology (CSIC) and the University of Lleida, have recently published a letter in the journal Conservation Biology, exposing the arguments that militate against the cloning of Pyrenean wild goat and exposed, among others, the following arguments:
- The genetic material for cloning belongs to a single old and sterile female highly inbreeded and with congenital heart disease which leads to pathological problems and lack of genetic variability.
- The technique of cloning is an expensive method, with uncertain results and an extremely low success rate. Animals born by this procedure are often malformed and exposed to the problems of premature aging.
- In the past it has invested considerable sums of public money on this project. This reduces the budgets allocated to environmental monitoring and other conservation projects with higher priority.
- From a more general point of view, scientists argue that the “de-extinction” of extinct species, reduce worldwide interest in the conservation of nature and relaxation of species recovery programs.
- In addition, the revitalization of dead species raises a number of ethical problems or even religious (think for example in revitalizing humans)…
