Blue Planet II

I was about to say how interesting it was and how frightening the amount of bleaching of the Great Barrier Reef.  But unfortunately ruined by the fact they feel necessary to subtitle the French diver who is speaking in excellent but accented English.  What Next subtitles for anyone who doesn’t speak RP, like me?

One interesting fact was that parrot fish excrete the waste coral as sand. Next time you are lounging on that idyllic beach remember it's a pile of fish poo. 

This 'rock' of ours, and by ours I mean all forms of life living here, is unique. We individuals can only hope for a minute first hand experience of this most complex planet. We are here only once and then only for the briefest of encounters. Programmes like this provide spell binding and wonderful insights for the majority of us visitors, the likes of which we can only dream of.
