The rotation/organic/etc argument is that properly managed soil & fields sustain their yields indefinitely with significantly less fertilizer, water, etc input, whereas the traditional industrial ag model achieves higher yields initially but the soil quality & yields decline rapidly & require ever more fertilizer, water, etc input. In short, the first model has lower peak yields but is more sustainable; the second has higher peak yields but "uses up" the land, and within only 1-3 decades at that. A related example of the consequences of "using up" land can be seen with bananas. In that case, a deadly banana fungus is slowly, inexorably spread through the soil by human activity. Eventually a plot of land becomes unusable for growing bananas due to the spread of the fungus. No matter, the banana company just cuts down more rainforest for new land and abandons the old plot. Later, in perhaps ten years, the new plot will be contaminated & unusable, and the cycle continues.
