I feel like in educating children it is something we overlook: wonder & curiosity come from an attitude of gratitude. When we work with nature, when we grow our own food, when we save seed & when we cope with difficult situations (usually outside our control), we grow in fundamental ways. All our ancestors learned the lessons we (collectively) lack by living day to day life, but we are disconnected from our food, the earth's cycles & our history. Using permaculture we can reconnect to those forgotten patterns of living and reconnect with our baseline of gratitude.
Here's an example: we all used to express real gratitude over each meal because we planted it, tended it, raised it, harvested it, processed it, cooked it &/or baked it; we have ownership. Self reliance = taking responsibility = ownership = maturity & gratitude. It's difficult to be more than fleetingly grateful for a frozen instant dinner. Some might say it's extra work, but the holistic yield is peace, gratitude, & satisfaction which are some things our society struggles with.
Plus on the pragmatic side, children should be growing most of the food we all eat, learning the science of it, & gaining real skills, gratitude & humility. The sitting they do for 12 years in public school is a slow motion crime. It's time to set them free & let them learn something real & vital, not an abstraction.
You touch on two things that is lacking in our society. 1) Growing our own food. Starting out with Non-GMO seed, planting, growing, harvesting, then saving seed for next planting. Enjoying the wonderful flavor of a Tomato, or any other thing that has been grown in the garden, doing it yourself, one cannot help but be grateful. Not to mention how wholesome it is for anyone eating organic.
2) The schools are teaching the children how to be dependent on governments, power utilities, and of course they must go to College. Higher learning is always achieved by doing. When, and not if the electric grid goes down because someone hacked into it and shut it down, our society will be demanding that our government provide for them in time of need, and of course that will not happen. Knowing basic skills and being less dependent on others is always peace of mind, and being Grateful for the peace of mind.
