There is much hype around the idea of bringing the Passenger Pigeon back from extinction. However, ‘de-extinction’ is a fantasy that is not grounded in science. The proposed plans for ‘de-extinction’ would create a new organism that is not likely to be viable in the wild. Thus, ‘de-extinction’ as proposed is unethical both because it could lead into the release in nature of a new genetically created organism and because it is not honest to claim that it would reverse the (...) extinction of the Passenger Pigeon.
