ROCHESTER, MN—Hailing it as the best-tasting and most satisfying such product on the market, vegetarian food manufacturer Greenwood Farms unveiled a more realistic meat substitute Friday made from soy raised in brutally cruel conditions.
Now I'm curious if plants have enough complexity to their internal experience for it to be possible to be cruel to them or not. One is used to thinking of them as basically inanimate apart from that they grow, but some of them can sort of communicate with other plants in certain ways can't they?
There is not really strong evidence of plant sentience. Here's one paper looking at it:
A. Plants do not show proactive behavior.
B. Classical learning does not indicate consciousness, so reports of such learning in plants are irrelevant.
C. The considerable differences between the electrical signals in plants and the animal nervous system speak against a functional equivalence. Unlike in animals, the action potentials of plants have many physiological roles that involve Ca2+ signaling and osmotic control; and plants’ variable potentials have properties that preclude any conscious perception of wounding as pain.
D. In plants, no evidence exists of reciprocal (recurrent) electrical signaling for integrating information, which is a prerequisite for consciousness.
E. Most proponents of plant consciousness also say that all cells are conscious, a speculative theory plagued with counterevidence.
Though something interesting and perhaps counter intuitive to note is that even if we realized plants were sentient, a plant-based diet actually involved killing fewer plants due to the lessened need to grow feed (of which most of the energy is lost)
Let's say that plants do have some kind of sentience, which is probably very limited due to the evidence we do have. Animals still have more advanced sentience that is closer to our own so it would still be the lesser evil to eat plants. Like why would you eat other people or chimps when there are other options available?
It takes a lot of mental gymnastics to be able to say that plants suffer the same way as animals. I know you're not saying this, but you do hear stuff like this based on this premise.
You can't eat anything in the modern world without killing animals. A combine harvester harvests wheat and mice. A hundred meat eaters are responsible for a single cow death, and the cow lived on marginal land, drinking from streams - you couldn't grow other food on the land (sure some are grown on perfect fertile land, they don't need to be)
Not saying I'm a meat eater, I don't care about mice, but there's blood on all our hands
Statistically, that cow had a short and miserable life in a factory farm before being killed at a small fraction of their potential lifespan. They were fed a grain-based diet that caused far more mice deaths than it would have to use the land to grow crops to feed humans directly.
Even in the situation you've presented, which again is an exceedingly small percentage (<10% globally, <1% in the US), land is being used which could be rewilded to promote biodiversity. The cow in question is still contributing to GHG emissions and will again be killed around 16 months of age.
Of course, but livestock require even more agriculture to maintain than the same caloric/protein intake of plant based. So if the choice is 50 animals or 100 animals then the choice is easy.
They can detect tissue damage and grow away from the source. So being physically cruel to a plant would definitely affect its growth. And yes, they can also share some types of information and resources with their neighbours.
They are living things. We shouldn't seek to deliberately cause pain if possible. While I like how stuff like bonsai trees look, I also feel a bit bad for them, wired and snipped in so many places and forced to be grown unnaturally small.
Or people who deliberately carve graffiti into trees with a knife.
Plants and trees have interestingly complex communication networks. We barely understand their microfauna and underground microbiomes that allow forests to grow much healthier and disease-resistant than our backyards. I have a funny feeling we know a lot less than we think we know, like when scientists discovered that babies can actually feel pain, or that dogs realize when they are treated unfairly. Stuff discovered within our lifetimes, lol.
