Yep... Every serious discussion. All sorts of eccentricity on the less serious end. Technically though, there are a lot of animals most wouldn't see as native to Britain which went extinct at some point in the last 60ky.

Lynx and more raptors are the two on the immediate agenda. Wokf and moose (elk) may be at some point relatively soon. Wolves would likely be big game changers for red deer population dynamics, and livestock farming.
