I would like to know how long the seals have been doing this? Is this a natural thing for them to do or did they just take up this activity in the last few years. If this is common behaviour - and I know it sounds like I'm answering my own question, but if they are like other seals in the wild, I would assume that this is their way of feeding themselves. What could be more natural than this? So therefore what right does this group have to cull/murder them?
