Should EXTINCT animals be brought BACK?

TASMANIAN TIGER

National Geographic published today an article about bringing back from the tomb extinct animals through genes manipulation.

Can it be done?

Scientist have made huge advances with cloning technologies and new methods of reading and writing DNA may lead to a genetic proximity of the extinct species whenever DNA can be retrieved from a preserved specimen.

But there are some controversial issues which have been discussed concerning the advantages, or not, of bringing back extinct species.

Isn't it true that, at the present moment, there are so many species in risk of disappearing in the next decade? Shouldn't all efforts and resources be focuses on those species which can still be saved instead of trying to produce miracles on reviving those which haven't their specific environment anymore?

The idea of reviving a specie looks tempting but shouldn't we look straight forward the future?

The discussion is open among scientists and in my opinion it would be interesting to have a Tasmanian Tiger on Earth again, although Indian Tigers are collapsing, as well as Siberian or Sumatrian. 

I remember posting here about the last 3.200 Tigers in the Wild. 

Can we do something NOW in order to prevent cloning these beautiful animals in the near future?

Lets worry about the future and not about the past.
