Demitarian

As the human population increases and more of the world develops, consumption of animal products increases and the associated nitrogen pollution poses substantial threats to the environment. Nitrogen compounds have been used in synthetic fertilizers since the 1900s, causing significant alterations to the global nitrogen cycle. Since then, humans have more than doubled the amount of simple nitrogen compounds in the biosphere, contributing more nitrogen compounds released into the environment than all other natural processes combined. This overabundance of nitrogen compounds flows freely through the globe causing many environmental effects before becoming neutralized. Conversion of nitrogen into (N₂) gas, or incorporating it into stable molecules, can neutralize the ecological harm of nitrogen.

Approximately 85% of crops produced are used for feed for food animals, which is significantly less efficient than if the crops were used to feed humans directly. Animal wastes and nitrogen-containing fertilisers are used to fertilize the pasture and crops they consume, thus intensifying concentrations of simple nitrogen compounds. Cereal crops are often excessively fertilized with nitrogen compounds, which greatly increases leaching of simple nitrogen compounds into air and water, and increases the rate that soil organic matter decays. Leached nitrogen compounds find their way into aquatic systems causing algal blooms, acidification and eutrophication, leading to fish kills and further losses in biodiversity. Nitrogen oxides that finds their way into the air combine with other greenhouse gases to form ozone, which is harmful to human health and contributes to climate change.

According to the European Nitrogen Assessment (ENA), the single most important thing we can do to minimize these effects is reduce per capita meat consumption.[4]

Demitarians consider meat to be an important source of protein and other key nutrients as well as an important dietary tradition and societal norm. However, it is recognized that primarily in developed countries meat consumption has gone beyond the healthy requirement and has entered into the realms of excess and overindulgence.

The average North American consumes 121 kg of meat per year or 331 g of meat per day. The average European consumes 91 kg of meat per year or 249 g of meat per day. In China, 54 kg per year of meat is consumed per year or 147 g per day. Africans consume 14 kg of meat per year or 38 g per day. Average global consumption is 39 kg per year denoting North Americans consume over three times the global average.[5] Not considering any other sources of protein a person would typically eat in the same day, the average North American eats enough meat to support a 223 lb person and Europeans eat enough meat to support 168 lbs. Whereas Chinese people eat enough to support 99 lbs of body weight and Africans eat only enough meat to support 25 lbs.[6][7]

Meat has been linked to the development of colorectal cancer and increased tumor development in patients with pancreatic cancer. There are correlations between lung cancer and consumption of sausage and ham in female non-smokers. The consumption of fried or well done meat has been shown to increase the risk of breast cancer, ovarian cancer and endometrial cancer. The additional saturated fats from meats have been proven to increase incidences of heart disease, stroke, diabetes and hypertension.[8]

A diet rich in fruits and vegetables not only reduces the risk of cardiovascular diseases and cancers but also helps to maintain healthy blood pressure and proper bowel function. Diets high in vegetable consumption are associated with lower body weights than diets high in saturated fat and excess protein. Eating fruits and vegetables also helps prevent bone loss and the developing of kidney stones. A well balanced diet also contributes to healthy hair, skin, nails and improved mood.[9]

Reduction of meat consumption and an increase in the consumption of whole and natural foods helps to support a healthy immune system and reduces the risk of disease.

For many, the choice to eat meat is a matter of ethics, religion and personal responsibility and for some it's a right. Vegetarians contend that any argument to cut back on meat is an argument to quit meat altogether. Demitarians can be seen as “sitting on the fence” and not being fully invested in the environmental cause. However, any effort to reduce consumption of animal products should be viewed as a step in the right direction.

Meat has been an important aspect of the modern way of life for many people in developed countries and many are reluctant to give it up “cold turkey”. The Demitarian Diet is an effort to bring conscious awareness to where meat comes from and how it is produced. The ability to purchase meat is a luxury, Demitarian diet is a way to bring awareness to the effect that luxury has on the planet and our ability to negate that effect through our habits and personal choices.[10]
