Economic vegetarianism
[1] Economic vegetarians believe that nutrition can be acquired more efficiently and at a lower price through vegetables, grains, etc., rather than from meat.For example, in the United Kingdom, necessity changed dietary habits during the period around World War II and the early 1950s, as animal products were strictly rationed and allotment or home-grown fruit and vegetables were readily available.[5] In developing countries people sometimes follow a mainly vegetarian diet simply because meat resources are scarce or expensive compared to alternative food sources.[6] These price increases make it hard for low-income households to continue to include meat as a part of their diet.Many economic vegetarians also promote the idea that advanced agricultural techniques have made the production of meat outdated and inefficient.
