Is de-extinction a good idea?
The possibility of bringing back extinct life has long held a certain
fascination for people. How many of us saw Jurassic Park and wondered
if, one day, it would really be possible to bring species back from the
dead? While we'll never resurrect the dinosaurs, technology is reaching
the point where we can soon bring back some of the species that went
extinct within the past few tens of thousands of years. But should we?
Though dinosaurs are absent (we have none of their DNA to work with),
the list of candidates for de-extinction does include some iconic
species. Among more unknown species like the Cuban red macaw, passenger
pigeon and Xerces blue butterfly are famous beasts like the woolly
mammoth, sabre-tooth cat and the Tasmanian tiger (or thylacine).
Proponents state there are great benefits to de-extinction. They argue
it will restore diminished ecosystems and help recreate fertile
environments such as the "Mammoth steppes" of Siberia. The techniques
developed for de-extinction will also aid the conservation of endangered
species. As well as this, they argue we have a moral duty to bring
species back if we can - especially if we helped drive them extinct.
However, others have severe concerns. De-extinction could take emphasis
off conservation, depriving endangered species of much-needed
attention. The moral argument might make sense, but as Brian Switek
argues we could be repeating our mistakes in bringing a species back
without thinking about its future. Another issue is where these animals
are going to live, as well as how we will protect them. There may be
little sense trying to bring back mammoths when we're failing to protect
the elephant species we already have.
