Druidic Farming

[flumphy]

Well, we have to keep in mind what this is going to do to the soil. Presumably the druid doesn't have access to modern fertilizers, and while she may know about crop rotation techniques, too fast of a harvesting cycle won't leave time for the land to lie fallow or maybe even allow the previous crop to decompose. The plants she forces to grow with magic will probably still grow, but after she's done...

Are we assuming the druid cares about doing this ethically in regard to the environment? And if so, how do we get around this issue?
