What we eat, and the methods by which our food is produced, are of greater personal importance than many of the other issues described in this book. Environment, culture,religion and personal values influence our diet, including vegetarianism and which, if any,meat can be consumed. Personal beliefs also influence views on the acceptability of food production methods (animal rights, use of agri-chemicals, and especially genetic modification), as well as working conditions and the pay of those producing food, e.g. fair trade,and our relationship with food producers, e.g. local or distant, individuals or corporate. Our values, personal relationship with the environment, and cultural filters (Pepper, 1986) influence what we will buy to feed ourselves. They also influence our views on which potential food production methods are acceptable. The average supermarket shopping trolley in the western world contains both national and imported foods. As we go around a supermarket,we make choices which affect individuals, regional and national economies, international trade and transnational corporations. Our choices also affect biodiversity, land cover, travel,energy use, working conditions and cultures.
