    “Know” is a stretch. Plants respond to attack by releasing chemicals (e.g. nettles and grasses), curling or retracting their leaves (e.g. acacia), or by changing their morphology (e.g. holly); but they have no nervous system - let alone a brain - so it’s not like you’re killing an animal.

      We don’t know how consciousness works enough to say they don’t. Having a brain and/or nervous system might not be necessary.

      They don’t have muscles either, but some plants are known to uproot themselves and fucking move.

        Yeah, plants aren’t stationary. All plants move, just very, very slowly compared to animals. Looking at time lapse videos of vines growing, reaching out for something to grab on to and stuff is pretty neat. They kind of whip around in circles until they feel they’ve hit something worth grabbing onto.

        Hmm sorry but no, there are traits exhibited by conscious entities which we don’t observe in those which lack consciousness. This is a nice explainer on consciousness, note that it’s not saying anything about needing a brain to exhibit those traits

        Some of them eat oysters, or so I’m told. They lack a brain and centralised nervous system.

          One of my exes is very strictly vegetarian and will eat oysters. Oysters lack the capacity to consciously be aware of themselves or the environment, effectively they’re a water pump made out of meat, and they’re one of the most sustainable foods we can make leading to less planetary harm than a lot of plant crops even. It’s definitely a controversial opinion though

      Plants having no nervous system is being challenged with the idea that the plant itself is its central nervous system.

      They react to stimulus, they emit sounds (different ones when in “pain”), and communicate with each other.

      They don’t have consciousness in a way we understand

      I dont mean this as a “dunk” but more of a how neat is that

        It’s always funny to me how people eat up the concept of a distrubuted neural network in tech but scoff at the same idea applying to something like a tree or a fungus.

        Pando is the largest organism by area, and the Humungous Fungus is the largest by mass. The idea that those organisms don’t “think” in some way is laughable.

          It always seems lime some excuse in a counter response by vеgаns

          The number of times I’ve responded to them telling them that plants probably process pain in a different way to us has always been shot down by them

          Tell them that brains extremely simplified are just on and off responses to certain stimuli / information just like plants have specific reponsonses to stimuli and computers having 1’s and 0’s that respond to information

          A mycelium network could be counted as a brain

          because humans invent things from scratch that nature has already created and optimzed, it’s why we’re seeing a lot of optimizations on current tech that comes from nature itself.

          It’s a really weird problem to have.

      They have the knowledge and are doing something about it. If other plants can send out this chemical by observing it themselves, that sounds like a reaction from a communication. It may not be cognition like we expect but it is behaving like cognition would. Hard to argue that plants don’t know or care of their friends start dying.

        I’d argue that knowledge is more than that, otherwise books or state machines could also be said to know things.

      by this logic do people even truly exist. Maybe you’re just the only real person in the world, maybe im the only real person in the world, we have no way of proving this.
