Can a tree be “strategically responsive, and exhibit kinship, or
a sense of self? Is a tree intelligent?”
– Rebecca Giggs, “The Trees Are Talking,”
The Atlantic, July / August 2021.
This intriguing article in The Atlantic recounts modern discoveries
of behavioral complexity in plants and the implications of this
complexity. Reading it, I was reminded of my conversations with two
different people about the possibility of plant consciousness. If
plants can be scientifically shown to experience themselves and
their surroundings with their own forms of biological consciousness
and sensitivity, how does this discovery affect the case for animal
rights, based on animal sentience?
My first conversation was with animal rights activist and author,
Norm Phelps (1939-2014) who, while believing that the world is
informed with a Buddhist-like spirituality, did not believe that
plants – trees, bushes, vines, grasses, etc. – possess consciousness
or sentience of any kind. Yes, like animals, they have DNA and are
organic like animals, but unlike animals they cannot run away from
predators and they lack a brain and a central nervous system. As
Giggs writes in “The Trees Are Talking”: “The notion that plants
‘do’ anything, outside of surging toward the light and siphoning
water, would imply threshold competencies that have long been
regarded as mental, or at the very least sensory.”
There’s an understandable concern among animal advocates that if
plants can be shown to be conscious, sentient beings, the case for
animal rights collapses into a welter of universal pain and
pleasure, making it hard to argue that we should not harm and kill
other animals since they, like us and unlike plants, have
well-developed central nervous systems, pain receptors and pleasure
centers. Like us, birds, fish, and our fellow mammals show evidence
of fear and wellbeing. Land animals – mammals and birds – cry out in
pain; birds, fish, and mammals nurse wounded body parts, and seek to
avoid those who have hurt them in the past. Thus, whatever sensory
experience plants may or may not have, there is no question about
the sensory experience of animals, be they chickens or chimpanzees,
underwater dwellers or insects, whose sentience is increasingly
recognized.
Vegetarian peace activist and coauthor with her husband Scott of
Living the Good Life, Helen Nearing (1904-1995) said that we may
assume a degree of sentience in plants and still recognize that
there’s “clearly a distinction between a new-born baby lamb and a
newly ripened tomato.”
My second conversation, more recently, was with a person who cares
about animals, though not about animal “rights” per se. Our
conversation began by his saying he looked forward to visiting a
friend with a fishing business, and to fishing with his friend. I
asked how he felt about hooking a fish painfully in the mouth and
yanking the fish out of the water that a fish needs in order to
breathe. For the fish, fishing is a mental and physical trauma
involving pain, fear, injury, and a slow and terrifying asphyxiation
comparable to our being hooked in the mouth and drowned.
He replied that pretty soon plants will probably be shown to feel
pain and suffering similar to pain and suffering in animals; if this
is so, we will be just as guilty for hurting and killing plants as
for hurting and killing animals, including fish.
I said I agree that we should refrain from assuming that plants have
no experiential equivalent of what we know in our own lives as
feelings. Even if plants don’t experience pain and pleasure in our
sense. this does not necessarily exclude experiences particular to
plants that involve their sense of themselves and the relevant parts
of their environment. “Experience” may comprise more than we know.
Surely all organic beings, be they plants or animals, have an
experiential component that distinguishes all of us from inanimate
objects.
The fishing discussed in our conversation was not “survival”
fishing, but rather “recreational” fishing, including “catch and
release” fishing, which is profoundly cruel to the victim whose
trauma is maximized by being returned to the water with mouth and
facial injuries as well as brain damage from the lack of oxygen the
fish endured when swung at the end of a pole into the air. Back in
the water, the injured fish is no longer fit to defend herself or
himself from predators and other dangers, as before. A lingering
injury to the body and mind of the fish, inviting infection, may
follow. The damaged fish may have an aquatic family that he or she
can no longer protect or participate with.

The premier advocacy organization for aquatic animals, Fish Feel,
cites the following:
In his book Pleasurable Kingdom: Animals and the Nature of Feeling
Good, world-renowned animal behaviorist Jonathan Balcombe, PhD,
explains how fish are falsely, yet "commonly denied feeling" perhaps
because of "their relative lack of facial expression." He states:
When they are impaled on a hook, fish don't scream or grimace,
though their gaping mouths may evoke a look of shock or horror to
the empathetic witness. Using facial expression as a guide for
sentience is hardly valid when one considers that some of the most
intelligent and highly sentient marine vertebrates – namely the
dolphins and whales – also lack facial expression, at least any that
most of us can readily detect. However, animals have many other ways
of visually signaling their feelings. Crests, dewlaps, pupil
dilation and contraction, color changes, and body postures and
movements are among the many visual ways fish and other animals
convey emotions. Water is also a potent medium for communicating via
chemicals and sounds.
The idea that if plants have feelings we may therefore harm and kill
animals for our appetites and amusement, since sentience is no
longer considered a feature unique to animals, but a trait inherent
in life itself, is morally untenable and devoid of empathy for
either plants or animals. People who argue against animal rights by
invoking the “suffering” of a carrot in being pulled from the ground
and eaten tend to be less concerned about plant sensitivity than
they are about asserting their right to exploit animals, armed with
the notion that if all living things have feelings, then “All is
permitted.”
For those of us who truly care about not harming plants needlessly,
it helps to remember that when we eat animal products, we consume
many more plants indirectly than when we eat plants directly,
because farmed animals are fed huge quantities of grasses, grains,
and seeds to be converted into meat, milk, and eggs. An animal-free
diet causes fewer beings to suffer and die for us.
Surely, we should treat trees and other forms of plant life with
respect, and not wantonly, whether or not they are conscious and
sentient as we experience these attributes. In “The Trees Are
Talking,” we are introduced to “a new vision of tree life. . . .
This newfound tree is networked, sensitive, companionate, and
communicative; it matters as part of a conjoined whole. . . . Such
findings make trees seem capable of so much more than we once
imagined.”
Similarly, oysters, clams, and insects are being shown to be capable
of much more than we once imagined [aee
Animal Rights Vegan Guilt]. Like fishes, they are members of
the animal kingdom. As such, they deserve the benefit of the doubt.
Their behavior indicates sentience and awareness even if the sources
of their feelings are elusive to science, which apparently is not
even the case anymore. Neuroscientist Lori Marino points out, for
example, that there are “close to one million neurons in an ant or
bee brain.” All insects, she writes, “possess a complex central
nervous system . . . and many insects show very complex learning
capacities. . . . [and] we found that fish and crustaceans feel pain
when it was assumed that was just not possible for ‘simple’
organisms.”
We are reminded that there may be ways of feeling being alive in the
flesh, even in wooden “flesh,” that we will never fathom. Nor is the
perception of pain per se the only proof or sine qua non – an
indispensable condition – of sentience. Conscious perception of
nonpainful but highly distressing stimuli includes gagging,
inability to breathe (dyspnea), smell of blood, apprehension, fear
and more. Throughout history, various groups of humans, birds and
others have been dismissed as mindless and insentient or “low on the
scale of evolution” as was once assumed about ground-nesting birds
such as chickens, until the truth showed otherwise.
Thus, even if Buddhism does not regard plants as sentient or
possessed of awareness, and therefore in no need of the compassion
we owe to animals “not to kill or injure any human, animal, bird,
fish, or insect,” we can no longer rely on this assumption, any more
than on the Biblical claim in Matthew 6:28 that the lilies of the
field “neither toil nor spin.” With our newer insights into plant
life and ecology, it appears that in their own evolved ways, this is
precisely what “the lilies” do, just like animals, just like us.
Taken together, we, the plants and our animal kin are the conjoined
family of life on earth.
