It is estimated that in the year 2015, 55 percent of the worlds population will live in urban areas. In some regions, such as Europe, North America and Latin America, over three-quarters of the population is already urban . As cities have developed, they have pushed agricultural land further and further from their boundaries. Agricultural systems are increasingly owned by open-loop agribusiness corporations who are focused more on the bottom line than on planetary or individual health, and rely on the use of fossil fuels, chemical solutions to land driven infertile through overproduction, genetically engineered crops, and undocumented and unprotected migrant laborers. Small-scale farms are diminishing leaving communities struggling to develop local economies, and those who remain on the land often need to work off the farm to keep the farm alive.
