Hi Richard, took a look at this so a few thoughts, just my opinion of course...
1) The language of the kids seems very advanced for 12/13 year olds, facilitator, concensus, buy in... seems more like a management meeting.
2) No food or water when they are trekking with a teacher, sorry that doesn't seem right or believable, surely they'd stop for lunch at some point. And the water all being polluted, seemed a little convenient.
3) None of them have their own phones?
Having said that, there was a lot I liked in the 'process' and the way the goup frctured... BUT it didn't ring tru for me in the way it's currently set up, but I think with a little more work this could be fixed.
