In the industrial agriculture of today lot of energy work is inserted in the system to produce food. About 10 calories per calorie of food of additional work on top of what is needed to the crops to grow (sun, land, water, etc) that would be needed anyway.
Most of the current improvements of this kind of agriculture are directed on technological development to increase the production and reduce the energy consumption. The use of fossil fuels provide most of this energy, and allow a single farmer to produce food for many peoples. In US, farmers account for about 1% of the population.
However, we have many reasons for not using fossil fuels at all. "How are we going to feed an extra two billion people without destroying what’s left of the natural world, especially under the stress of climate change"? I like this answer: regeneratively intensify food production on the same amount of acreage
It is not enough to change at a local scale, global trade alternatives are necessary to put humans first, then markets and profit.
