Being a homesteader and living off the land often means being subjected to natural conditions beyond our control, sometimes predictable changes of seasons and temperatures, other times curve balls such as unseen pest pressure, hard frosts in late May or heavy snow in early November. A lifestyle where these natural circumstances is the main determining factor for what gets done when is getting increasingly rarer – humans have gained what some consider an advantage by manipulating the world into a state where we, in many ways, can remain unaffected from the forces of nature.
