As I said, draft animals are great, and I'd dearly love to own a team
of horses, and have owned horses in the past but only riding and pack
animals. However, another problem with converting to horse power is that
all those big farms would have to be broken up first. Look to the Amish
to see what sort of field size is compatible with horse farming.
But the main thing that would interfere with a switch to draft
animals for farming is that it is absolutely trivial for a farmer to
grow and make his own fuel for his tractors, and it would take only a
very tiny percentage of his cropland to do it.
The exponentially accelerating price of fossil fuel based fertilizer
and pesticides is a whole different matter, and it is that which will
serve to destroy the current industrial agribusiness. Hopefully.
