They have lost the knowledge they had, and what has replaced it is neither relevant nor useful. In a lot of ways, it is just like the loss of genetic diversity. High-yield hybrid seeds have replaced a rich variety of local cereals across the world, improving harvests but also making the crops more susceptible to disease and dependent on costly inputs of agrochemicals.
