I have seen it in French (see here-under comments specific to the broadcasting in France, in French, I guess it would have been even better in English), but the main point is here : just watch it, it's absolutely magnificent, with a high density of rare views from far above and sumptuous images and well selected stories and subjects ! One just want to go there and see more of it ! And of course, first of all, one want to see the other episodes of the series, if not seen yet !
seen on the French TV channel France 2, series "Grandeur Nature", sat. Nov 4th, 2017, 3pm local time, with the familiar voice of Mathieu Vidard, well known science show runner, famous on France Inter radio channel
however, as usual on French TV channels, there was little or no proper reference to the original source of their documentaries - often, for the best ones, it's BBC-, luckily we have IMDb, for this link http://www.bbc.co.uk/programmes/b093xhxm/episodes/guide
