//webbo: But that was her JOB//
No it isn't. She's an actor. She need not roam the globe making documentaries for TV. If she was really worried about the effect air travel has on the environment she would have the filming done by local crews and she could voice it over or if this was unsuitable then not made the programmes at all. She's advocating that people adopt "sackcloth and ashes" and return to conditions similar to that experienced in the wake of WW2. Well at that time they didn't have a telly, let alone be able to watch actors strutting about the globe.
Similarly with politicians, there is no need for them to galivant around the world, shaking hands and having agreeable dinners. The "G7" leaders met in Cornwall in the summer, causing havoc in a totally unsuitable location (and as an aside caused a huge spike in Covid cases in that area). The "G20" is meeting in Rome even as I write. The "COP26" begins its month long jamboree on Monday. The President of the USA alone causes his own emissions explosion every time he moves. At least four huge aircraft are involved and his equipment and entourage cause havoc and pollution wherever they go.
These are hypocrites. They pontificate and preach to the "ordinary" people they purport to represent, urging them to adopt all sorts of measures and restrictions that they have no intention of adopting themselves. Personally I don't care what they do, where they go and what they burn in order to get there. But I don't want them telling me that my taking a return flight to Mallorca once a year (which is far more important to me than their endless but pointless jollies) is "destroying the planet" or any other such catchphrase their lackies come up with.
