While we are on Farm Mod topic:
As I mentioned to Afforess in another thread, there is a possibility to make food resources disappear due to real bad weather/global warming. Since this mod won't make it into AND 1.6, we can sit down and discuss this new twist to food resources with global warming/desertifications/massive storms destroying food resources.
However, I may add this: if we are to use Resource Refinements with food resources, this would be a lot more realistic. We just need to figure out how to re-seed the food that we refined in a building and transfer that resource from the building to the tile
