In my humble opinion, if you are talking about a forest school where people can learn about foraging and different plants that they can source and take home to their little cottage and rustle up on a wood fire using appropriately sourced and cut wood... then I reckon that is achievable - I'm not sure if that is what is being carried out? But I don't think that has anything to do with well roundedness or resilience (for the most part).
I don't believe resilience or roundedness can be taught in "safe" environments.
Don't get me wrong, my mum is in her 70's and I want her to be able to be safe walking around the town etc... but for the most part, in my view, you have to work at getting yourself killed these days.
Visiting some of lesser H&S parts of S.E Asia last year really made me aware of my surroundings, aware of the fact that I really DID have to take some responsibility for my safety... of course things out of ones control can always go wrong, inc in the UK, but over here we have a man with high viz, standing behind a cone, in front of a sign, in front of a barrier, in front of flashing lights, in front of a bunch of other guys in high viz, in front of a big hole.... in other parts of the world, it's pitch black and there is an open works hole... top tip is to avoid falling into it.
My point? How can one learn to be resilient when there is very little to no risk? You can run through basics, theories and all that in safe environments, but mettle won't be tested unless someone is at risk of being cold, wet, miserable or potentially in a mild degree of danger..
Then we also live in a very fast world. Entertainment (at TV level) is no longer a case of waiting until next monday at 6pm when your favourite show is on, on that 1 channel and thats it... it's at your fingertips... so 'trapsing about a woodland doing things at a slow pace? Who wants to do that? I want an instant instagram campfire camping set up, with some instant instagram food, a great nights sleep and all without really thinking too hard about anything and I also don't want it to take hours...'
It's not a thought that is applicable to all people, adults or kids. But its my theory based on what I see in the world... is it the fault of the children/young adults? Or have they been pacified by parents who saw an easy way to raise children, digital devices... Or is it marketing and the worlds fault? I'm tech savvy enough to use devices at their user level (not beneath the device), but I feel like I have slipped in this world and been a little left behind...perhaps I should learn more to keep up with the world for employment prospects. Next day off, should I enjoy life outside? or spend my time playing with tech?
