I'll explain more about low external inputs and things we've learned mainly from third-world countries by example. We don't use a tractor, and we lower petroleum input to almost nothing. It's very much more labour-intensive. And everything on the farm tends to have a dual purpose. Our goats provide manure for our rare-breed vegetable plot. In turn, the byproducts in the vegetable plot will feed our goats. We do zero-till planting, so we don't need that tractor. It's very labour-intensive. Everything is done by hand. Basically, we're reducing things coming into the farm to almost nothing.
