Beats me on that. All I know about their farming is what I learned living in a small town their for 4 years. Everything was penned up in small areas. They used a lot, a lot of plastic to cover crops. Rice, obviously. Not much wild life at all. I bet their are
books. I also bet a lot of those rice patties I saw had been there for centuries. They didn't seem big on change there. Lots of people with bowed backs.
