And see where I said for person use? I conveniently ignored that and all those crops, those crops are also grown on a commercial level as well, and assumed I'm being evasive when I answered honestly. This is showing that you're introducing personal biases. This indicates that you might be working towards the answer you wish to be , rather than being interested in the truth.
And I didn't grow up on his farm, you assumed by family unit. I have helped castrate pig a full grown pig (took around 6 adults) as well as young piglets and remember helping his get cows to get into a new area he opened up moving the electric fence.
I remember the well in the back that had little filter feeders that purity the water and how they died when an idiot left the top off so leaves could fall in.
