All of those are reactive. Lets say you cut yourself with a knife. That your blood clots and the wound heals is a reactive response. You don’t choose it, it just happens. That you then probably choose a less risky approach the next time you cut is you learning. I don’t have the time to watch the video unfortunately, but I read this article (do not plug that link into sci-hub.ee that would be pirating) which delves into the topic of plant’s having sensory membranes, conditional experiments etc.

Regardless, even if we assume that

a. Plants have consciousness
b. Killing consciousness is immoral/unethical/bad or whatever

then being vegan is still the more moral option since the amount of plants that need to be “murdered” to feed an animal until it’s ready for slaughter is orders of magnitude higher than the nutritional value we get out of the animal when we murder it.

I also think the notion that harvesting peas is the same as ramming a bolt through a pigs head is not really something people actually believe, but rather antivegan cope. But that’s subjective of course.
