Agriculture

Most agriculture is done intensively in closed, hydroponic systems. You find hydroponic farms either in multiple layers underground, or in glass highrises, acting as greenhouses, with mirror systems bringing in the maximum amount of sunlight.

Hydroponics are chosen in order not to damage the natural environment. Traditional farming is really much, much too expensive, when one takes the overall system into consideration. Hydroponic farms are closed systems where many of the resources are recycled indefinitely, and where yields are maximized per unit of space. No natural environments are destroyed to make space for them; they are constructed in addition to the natural environments.

Individuals and small communities might well do more traditional cultivation of open land adjacent to their living space. However, this is always in quite small scale and for personal consumption. Typically communities will prefer to surround themselves with relatively unspoiled nature, rather than with farmed land.

Inventive solutions to the production of agricultural products might appear. Think about floating farmland in the oceans or airborne zeppeliner greenhouses floating above the clouds.

It will be quite common for single family homes to have facilities for growing most of the food they need. Or maybe they will specialize in a couple of kinds of vegetables or fruits or grains and will exchange with their neighbors in the community.

Biodynamic agriculture is naturally the norm. The task in agriculture is to construct a system that is as self-sustaining as possible, as well as producing the crops that are desired. If there are significant amounts of supplements needed from the outside, or waste that needs to be led away, then it is a badly designed system.
