Ethical factors in food choices

As production has increased to feed a growing population, production of food can have some harmful effects, with impact on:

Environments (habitats, biodiversity, pollution)
People (mistreatment of workers, displacement of populations, inequities if food availability)
Animals that are slaughtered for meat

Along with health-value, convenience, and cost, many are increasingly considering ethical factors as they select or reject specific items. Some options include:

Organic
Free range
Fair trade
Kosher
Vegetarian/vegan
Buy local
Harvest your own
Independent (vs. corporate)
Packaging (plastic, paper, refillable, etc.)
