To add a little more to Rowanwithch, vegetarianism and veganism is really a rationalisation. And nothing terribly wrong with that belief. Atheist makes a claim of sentience (or in his post non-sentient). What does that mean in reality. Take some examples, plants take decisive actions against stress and danger. Your roses and clematis, fruit trees etc., don’t produce more flowers and fruits to please you, they think they might die and therefore produce more pollen and seeds to continue its life through progeny. If you are lucky enough to own a nut tree like a walnut, take a cricket bat to it for 20-30 minutes in the spring. Its nut production will increase. Perceived stress and danger.Let’s add a bit more to Rowanwitch and fungi communicating. Plants first. An example is the Acacia, a tree although a relative of the pea. In Africa, a target of giraffes for food. The Acacia tree, under attack by a giraffe will produce tannins to stop the hungry giraffe feasting. But so will every other Acacia tree within 50 -70 yards even if nothing is eating it. That demonstrates an inter species communication. Flowers of many species have been found to communicate with pollinators, like bees and insects. First, by sight. Outside of the human sight frequencies, flower petals display landing areas in ultra violet and infra red colourings, directing pollinators to the correct position. Further recent investigation shows plants sending electric pulses to pollinators. So proving intra species and extra species communication. But one more thing, Rowanwitch is absolutely right in the fungi communication system is absolutely right, and in local areas like copses and forests, provides an internet like communication capability for plant species to communicate in times of need. So, what is sentience. If your food decisions are based on a lack of pain, and loss of progeny, then plants clearly react adversly to both. You might like to do a little more investigation and put your rationalisation up for discussion.
