I have a more “dictionary” definition of sentience, as meaning the capacity to feel, and have a degree of consciousness. Even Michael Crichton (in his book, Jurassic Park) argued that the lowest kind of plant, say a potato, has a mean degree of sentience.

And there have been many documentaries about the organization of plant communication around their root systems - many of them. So it’s not really considered pseudo-science, it may just be an idea that is beginning to be understood.

And according to those very same documentaries, plants do possess the ability to process information. In human brains, which are much like a tangled root system, chemical processes are what create what we call “thoughts.” It’s the same in plant systems, chemical processes exist that enable plants to let nearby plants know if pests are chewing on them, if fire is near, and/or when they are ready to reproduce.

So I’m not really proposing anything that is unscientific here. And when did I EVER state that “veganism is unnatural?” You said that, I didn’t. I said we’re “omnivores,” which means were are physiologically designed to eat and grind up meat AND plant materials, both.
