Precisely, merlotgran.
Could proffer the same argument about David Attenborough and any of the other naturalists who bring us fantastic films and information of our wonderful world. They also bring to our attention many of the plights our wildlife faces. How else would they get to these places, Telly?
Thank goodness, too, that they are bringing to our attention the harm plastic does, but without travelling to different places, we wouldn't be aware of the extent of the damage, would we?
Air travel isn't going to go away any time soon, either. Too many people love their package holidays...
