The food business is far and away the most important business in the world. Everything else is luxury. Food is what you need to sustain life every day. You can't run a tractor without fuel, and you can't run a human being without it either.
Food is the absolute beginning.
In the 18th century, Thomas Malthus's population theory linked the potential for population increase to the availability of subsistence through access to fertile, agricultural lands. Second, the highly centralized consolidation of the global marketplace which concentrates the ownership and control of the world's food system in the hands of a few powerful players in the global economic marketplace. Third, the politicization and secrecy of access to the food system at the global-national levels. The concentration of ownership and control of the national-global food system impacts human survival and agricultural productivity, offsets national agricultural legislation, and affects the long term sustainability of the world's food system. The changes which brought this about have not occurred as a result of the public dialogue normally associated with the democratic process, nor is the information relating to this concentration of interests readily available.
