People all over the world rely on modes of production, distribution, and consumption in order to provide food and other commodities necessary in life. These modes differ based on culture in the ways that humans relate to and make use of the natural environment, how humans relate to each other, and how the institutions of society and federal states cause change. Production is the various forms of transformation of nature's raw materials into a form more suitable for human use. Distribution is the transport of produced goods whether that be by land, air, or sea to the consumer. Consumption is the buying or use of a good, food, material or service that has been previously produced and distributed. This section discusses specific aspects of the different strategies for these concepts that have been used over time and that continue to be used in different cultures worldwide.
