Becoming a Sumbiovore in the Symbiocene

Food in the Symbiocene


It’s time to include plants in the realm of sentient creatures. Sentience is defined as “… possession of sensory organs, the ability to feel or perceive, not necessarily including the faculty of self-awareness.” (Animal Liberation Front). A creature does not need a brain to be sentient.

We now understand that plants have at least 20 different sensory capabilities, can learn, store information, use memory to react to stimuli and share resources via symbiotic fungal and root community networks.

The hard-headed conclusion, based on this information, is that if it is wrong to eat sentient animals because they feel pain and suffer, it is wrong to eat plants because they too, as sentient living beings, can experience suffering in some form.

We cannot judge animal suffering to be more ‘serious’ than plant suffering because that would be ‘sentientism’ or the unjustified elevation of animal sentience over plant sentience.

As the philosopher Daniel Dennett put it, ‘cerebrocentric’ thinking is but one form of intelligence. Chlorocentric thinking and the ‘wood-wide-web’ are plant-based forms of the acquisition of knowledge and its use (intelligence).

Does this mean we  violate sentience even when we make vegetarian/vegan food consumption choices? The answer is yes. Do we then stop eating on the basis that all forms of food consumption are unethical? The answer is no.

The taking of life to give life is a universal feature of life. It is how  life is produced and taken that is the key ethical issue, now that sentience has been removed from the menu of primary ethical choice.

Industrial Agriculture

Modern industrial forms of agriculture (plant and animal) maximise an unethical relationship to those things we eat because they violate the very foundations of all life.

By polluting the local environment with excess nutrients, introducing toxins and carcinogens (cides) into the food chain, using genetically modified organisms that present an irreversible risk to human and ecosystem health, removing biodiversity and being fossil fuel dependent, industrial agriculture is a short-term food production system but a longer-term life-destroyer.

The overcrowding of animals and the unnatural conditions within which they live are also features of industrial forms of agriculture. Keeping life confined in ways that violate natural instincts to move, fly, bathe, dust bath and be part of a community of beings is ethically repugnant.

Killing animals after they are herded, transported long distances and placed in stress-maximising facilities (industrial abattoirs) is also ethically unjustifiable. However, death in the abattoir is likely to be more humane than death in a natural setting.

When the killing of farmed animals is local and regional, respect for life can be maximised. At the very least, mobile abattoirs make it possible to eliminate the transport component of the slaughter of animals for meat.

Climate Chaos

The pollution from intensive meat eating production includes substantial greenhouse gas emissions (GHG), depending on the types of system used to raise the animal. However, livestock production, at less than 20% of global greenhouse gas emissions compared to global emissions of up to 90% for cement production and fossil fuel use for use for transport and energy, means that abandoning fossil fuels has higher ethical priority than giving up meat eating because a stable and life supporting climate trumps all other considerations in the ethics of how we live.

Becoming a Sumbiovore 

Sumbiovores understand that health is a delicate balance of the parts (harmony) within living systems at various scales. From the microbiome of the gut to the role of the mycorrhiza of fungi, symbiotic interconnection between and within species is critical. In addition, grazing, manure, compost and bioturbation at local and regional scales, all assist in maintaining ecosystem health. Predation of herbivores by carnivores also has a vital role in maintaining ecosystem health.

Humans have already created agricultural systems that respect many forms of life and maintain the fertility of places that produce food sustenance over the long term. Sumbioculture in the form of permaculture, agroecology, some organic and biodynamic farming are consistent with the health of whole, complex ecosystems. They are viable alternatives to industrial agriculture.

Sumbiosic food is food produced by humans that enhances mutual interdependence between the non-living foundations of life (biogeochemical systems) and all species as living beings. In doing so such food production will conserve and maximise the living systems that constitute communities of life. Sumbiosic food celebrates the interconnectedness of life (living together) and the unique characteristics of place and culture (terroir).

The consumption of sumbiosic food from sumbiosic agriculture will entail a tougher ‘standard’ for food than ‘organic’ as organic systems can currently be monocultures and have no necessary connection to the foundations of life in bio-regional contexts.

If you eat sumbiosic food you are a sumbiovore and being a sumbiovore requires a value system that overrides all other forms of ‘food-vore’ in the Symbiocene.

  1. Congratulations on understanding the food chain. Have you ever grown food? It might be a good idea to meet some people who do it full-time, before re-discovering basic biology [rolls eyes]

    All the same, it’s nice to see someone connecting with the facts of life.

    1. Hi, I live on 5 acres and grow as much of our own food as possible. I also keep chickens and practice permaculture. When an academic, I was a professor of sustainability (I am a philosopher) and would take my students to real farms so that they could experience the way agriculture works … both intensive and organic. I am amazed that most people have no idea about basic biology but it does not surprise me that most people do not know about symbiotic fungal networks and plant physiology. Many of the discoveries are recent so they open the eyes of many who do not have access to such material.


  2. Please read a introductory book on neuroscience or even just general biology before writing blog posts like this which may confuse uninformed readers. Reacting to the environment =/= sentience. 100+ years of neuroscience research has confirmed over and over that conscious awareness ie. sentience is only possible with a functional central nervous system, meaning it’s impossible for a plant to being sentient. Botanists are discovering that plants can react to the environment and process information in much more complex ways than previously thought, but there is no brain in the plant making conscious choices. Conscious thought evolved as a way to plan movements in order to evade predators and search for food, both things that plants are incapable of doing.


    1. Dogulas, the science is changing in this area on a yearly basis. Also, many of the interpretations of issues like consciousness and sentience are philosophical, not strictly scientific. I used the Animal Liberation definition of sentience in my article and on that definition, the latest plant science says that plants are sentient. I know it is a popular article, but have a look at this summary of contemporary plant science literature that features the work of my friend Dr Monica Gagliano. You might find that the science and the biology have moved on in the last few decades:
