I give this book 10 out of 10 acorns. It has stood the test of time; Peter was already writing as tho climate megacrisis is a current reality. which it was but few people saw it. It covers the ground of designing a homestead, as he says from .5 to 20 acres. I myself followed this pattern language in preparing my 20 acre homestead, Old 99 Farm, Dundas ON Canada.
I have not found anyone else with Peter's approach, what I call paint by numbers permaculture. After reviewing the background, principles and a design checklist, he describes about 70 elements that should be considered in one's design, depending on one's vision and goals. These can be played with dynamically in how they relate to each other, spatially and functionally. In the end, the designer is not likely to miss any major options for functions or elements.

Here in Ontario we have local cold pressed sunflower, hemp and flax oils produced organically near Port Burwell.
But why not use lard and tallow for most cooking where you don't need the oil to be liquid at room temp?
It's known for a long time that animal fats have been mischaracterized as bad for  health. Check out Weston A Price Foundation for details.
