Impact of a vegan agricultural system on health and society

Health and other social impacts

This section will be based on the following questions.

  • What would be the impact of a vegan diet on population health and health care costs? This incidence of diseases such as diabetes 2, heart disease, some cancers, etc, are known to reduce when on a vegan diet. This should result in less demand for medical services.
  • What would the impact be of the reduced risk of antibiotic-resistant infections, caused by the elimination of giving antibiotics to farmed animals?
  • How would the changes in agriculture impact food security?
  • How would a vegan agricultural system produce adequate nutrients for the Australian population, including calories, protein, fats, iron and calcium?
  • What impact would a vegan agricultural system in Australia have on exports of food to other countries?


    - "society may wish to recognise food products with lower
        environmental impact, including those with lower embodied
        greenhouse emissions." (LU p167)
    - "Across Australian society, red meat consumption per capita has
        reduced by about 46% since the late 1930s." (LU p168)
    - "There is increasing recognition that excessive consumption of
        meat and meat products is a contributing factor to poor human
        health outcomes.  A reduced meat consumption would benefit
        individuals and populations.  13 Friel et al.  (2009 14 )
        modelled the population health effects of a 30% reduction in
        red meat production and consumption for the United Kingdom, in
        view of a proposed reduction in agricultural greenhouse
        emissions of 50%.  This study found that the burden of
        ischaemic heart disease could be reduced by 15% in the UK.
        Meat production, whether pasture or feedlot-finished, produces
        less food per unit of resource invested than non-meat options.
