Life in nature as alternative to city life is far more demanding than life in cities - qualifications much higher than what most city population could offer.
Many consider alternate lifestyle an easy life. Easy work in your own garden or fields or farm. However living countryside is far more demanding than simple office jobs. The range of professional experience and knowledge far above office or IT employees and finally the work nearly infinitely harder than most office or factory jobs!
A typical farmer in small farming, organic vegetarian farming needs to know how to grow crop, vegetables, fruits and forests. He needs to have knowledge about different qualities of soil, water and other nature factors
In addition a farmer's earning is much lower, hence typical farmers do all repair on their own. Construction and repair of housing, carpentar work, mechanical work to repair and maintain all tools and machinery is normal. Hence a typical farmer needs extensive knowledge, experience and skills in mechanics, electrics, carpentar and construction work and its material used as well as forestry and other farm related work.
To be farmer - even a modern alternate lifestyle farmer - usually is born into that situation. It may take several decades to be fully qualified - to have sufficient expertise to avoid major mistakes and thus to avoid major losses. The prices paid in modern times for any and all kind of farming products or farming services never allow for any mistakes or losses due to mistakes to be made.
Children learn from fathers - ever since - and after decades of working together with father and mother, one day children are experienced enough to start their own independent alternate life style project - a home amidst nature.
