Darwin would have called us armchair conservationists, but this is even worse. While he was an armchair theorist (compared to Wallace), we may begin to spend our time and money trying to correct past extinctions. Tinkering is unlikely to be an answer to the continuing loss of biodiversity from every single habitat on land and water. Conservation of what we have is going to be much more difficult than some fairly basic genetic engineering.
Climate change is about to become the issue that many accept as even more important than wars and finances. We are being physically forced into action, despite the fact that almost nobody lives around the Barents Sea or even the Bering Strait.
When dolphins are 'rescued' in various countries, the car given seems to be ill-considered. We are simply looking at the success rate which is reported to be low, in most places. They could even end up in commercial aquarium shows, but they certainly rarely make it back to the sea.
