PPPick-up a Penguin?

Quite a fuss has developed about the Attenborough 'Dynasty series' filming crew in the Antarctic digging an escape route from a ravine for some trapped penguins (https://www.theguardian.com/tv-and-radio/2018/nov/19/top-filmmakers-back-penguin-intervention-on-attenborough-show). Arguments seem to revolve around the issue of the natural history film maker's code requiring them to not normally interfere with the lives of the animals they are studying (e.g. they would not be expected to intervene, on either side, in a predator versus prey encounter). The camera folk argue (not unreasonably) that no animal was probably directly disadvantaged by digging the escape slope (picking the penguins out of the ravine would have been different). Having said that, it could be the case that some, as yet unarrived, scavengers missed out as a result of the film-makers actions. I suspect, however, that I would have done the same under these circumstances.
