Vegan Book of Permaculture by Graham Burnett (page 12)
A vegan diet, that removes animal products off the table and yet includes non-organic produces, products that are manufactured in an unfair manner, or simply depends on the consumption of products coming from the other part of the world, might satisfy the animal liberation criteria, but falls short on other ethical aspects: it exploits land and people.
Building a Better World in Your Backyard, a book by Paul Wheaton and Shawn Klassen-Koop, demonstrates a chart of diets and their carbon footprint. The authors use the term SAD, referring to the Standard American Diet, and their invention VORP, that is Virgin, strictly Organic, Rich soil, and Polyculture/Permaculture. The VORP diet naturally means “low processing, low packaging, foods are grown in aged soil with a high organic matter level, […] seasonal foods, […] no pesticides”.
In their chart, you can recognise the same dimensions as in Garett’s Food Wheel. However the VORP model puts more emphasize on the food production aspect. According to Paul’s calculation, a VORP omnivore forest garden doesn’t only significantly decrease your carbon footprint but it actually removes carbon from the environment.
“Rather than saying that everyone needs to be vegan for the sake of the environment, I think that, by advocating for VORP food, we can have a much larger impact. Then each person can decide whether or not to eat animal products, depending on what works best for them.”
Masanobu Fukuoka is known to be the figure who did permaculture before it was called so. “He was a proponent of no-till, no-herbicide grain cultivation farming methods traditional to many indigenous cultures, from which he created a particular method of farming, commonly referred to as «natural farming» or «do-nothing farming».” (Wikipedia)
In his book, The One-Straw Revolution (1975), Fukuoka explains the four main classifications of diet (page 78):
"Human life is not sustained by its own power. Nature gives birth to human beings and keeps them alive. This is the relation in which people stand to nature. Food is a gift of heaven. People do not create foods from nature; heaven bestows them. Food is food and food is not food. It is a part of man and is apart from man. When food, the body, the heart, and the mind become perfectly united within nature, a natural diet becomes possible. The body as it is, following its own instinct, eating if something tastes good, abstaining if it does not, is free.”
Fukuoka’s natural food farming philosophy incorporates all previous considerations and talks about none of them at the same time.
"Unless people become natural people, there can be neither natural farming nor natural food. In one of the huts on the mountain I left the words, «Right Food, Right Action, Right Awareness» […] inscribed on a pinewood plaque above the fireplace. The three cannot be separated from one another. If one is missing, none can be realized. If one is realized, all are realized."
When choosing what you eat, you also choose the impact you leave on the environment. Realize your relationship to nature. It is you and it is apart from you at the same time. Therefore, your impact on nature is per se the relationship to yourself. Stop exploiting the environment. Stop exploiting yourself.
"Exploitative nature of who we are exists in all aspects of life. […] Fundamentally what needs to go is this urge to exploit anything and everything that’s little weaker than me. That should go. If that doesn’t go, people will find devious ways to do the same damn thing.”
