Covered bike racks at Fabrica La Estrella
Parras transportation gallery. There appear to be hundreds of bicycles hung on a series of covered bike racks at Fabrica La Estrella, just inside the entrance to the fabrica (factory). The bicycles are unlocked. The racks were manufactured in Torreón. Active non-motorized transportation offers benefits to its users' health, the community at large, and earth's climate. Covered bike racks, specifically, offer bicyclists greater status (as people worthy of finding a dry seat when they go to use their bike), and make bicycle parking a more emphasized part of the landscape. Improving the status of bicyclists is particularly important in Parras, as the bicycle is identified as a poor person's vehicle, and they are afforded little respect on the road. Drunk driving is rampant on weekends. It happens that on the morning of 4 June 2006, a bicyclist was run over early in the morning. In such accidents, as in this case, the driver most frequently does not stop. If covered bike racks are to truly improve the status of bicycles, however, they must be installed outside of the factory, as in this location they are intended to serve the the lower-class labor force of the factory exclusively, and are invisible to the greater community. Issues include the factory labor practices, waste water, etc. Long distance travel using bikes can be difficult. Also, bikes require frequent maintenance, whereas cars require less frequent but more costly maintenance.

Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells in an effort to produce energy, maintain life, and/or stimulate growth. Historically, people secured food through two methods: hunting and gathering, and agriculture.

Agriculture is the cultivation of animals, plants, fungi and other life forms for food, fiber, and other products used to sustain life. Agriculture was the key implement in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that nurtured the development of civilization. In the developed world, industrial agriculture based on large-scale monoculture has become the dominant system of modern farming, although there is growing support for sustainable agriculture (e.g. permaculture or organic agriculture).

Sustainable agriculture is the practice of farming using principles of ecology, the study of relationships between organisms and their environment. It has been defined as "an integrated system of plant and animal production practices having a site-specific application that will last over the long term: satisfy human food and fiber needs; make the most efficient use of non-renewable resources and on-farm resources and integrate, where appropriate, natural biological cycles and controls; sustain the economic viability of farm operations; and enhance the quality of life for farmers and society as a whole.”
