" But they can also be the most horribly intrusive devices devised by humans "
I certainly agree with that point, but since the times of Jacques Cousteau in the 1960's taking his underwater cameras to the Reefs of the Pacific and later, film makers like Sir David Attenborough filming places like the Serengeti, people in general have been able to see those places and appreciate their beauty and the need for protection and preservation.
It's fairly obvious that if you ask someone to preserve and protect something and they haven't a clue what it is they are being asked to protect, then interest and money contributions will be hard to collect.
Show them a film of a Coral reef, Patagonia, Migrating Wildebeest or even a Scottish Mountain and you will find that interest in preserving and protecting those things and places will increase,.
Clean Ocean Movements grew when people who would otherwise never have known what a Tropical Reef looked like, took an interest after seeing colour film of life on a Reef and how fragile it could be. Not everybody is rich enough or physically able to get to wild places, so in my opinion a good way of recruiting them to help preserve those places is to show them a film..even one taken by a Drone.
However, as always controls would have to be introduced but as to an outright ban I think it would be a mistake.
Brilliant. They picked one of the better times of year - late winter - but also visited places few visit. Very few go up Canal Magdalena, fewer still down Seno Agostini.
And 66 days to Faro Fairway! 66 days out and still quite a way to Puerto Natales.
Impressed.
I wouldn't worry about drones in Patagonia - I would be more worried about the cruise liners. They are a true blight.
