Modern business agriculture isn't really sustainable due to its heavy reliance on petroleum, a non-renewable resource of the power utilized in farming, and due to pollutants brought on by petroleum items corresponding to fertilizers and insecticides. A structures research of farming means that agriculture can be extra sustainable while prone of nature, akin to nutrient recycling by means of soil micro-organisms and ordinary controls of bugs, exchange the providers now supplied via power from petroleum. Examples are drawn from the Southeastern united states, yet classes realized may be utilized around the globe.

Rice paddies are flooded to control weeds, and also to allow the growth of the water fern azolla, which has a symbiotic relationship with cyanobacteria that fix nitrogen from the atmosphere. It is the weed control and the nitrogen availability that makes paddy rice so energy efficient. Energy yield efficiency for meat and poultry is low because energy has to travel an extra step through the food chain.
