植物也能感受疼痛吗？
植物没有神经系统和伤害感受器，无法有意识地感受疼痛。即便假设植物有某种感知，维根饮食消耗的植物总量也远少于畜牧业。 Plants lack a nervous system and nociceptors — they cannot consciously experience pain. Even if plants had some form of sentience, a vegan diet consumes far fewer plants than animal agriculture does.
This is one of the most common challenges to veganism. The scientific consensus is clear: plants do not possess the neurological structures required for conscious pain experience. They lack a central nervous system, a brain, and nociceptors (pain receptors). While plants can respond to stimuli, this is fundamentally different from the subjective experience of suffering that animals possess.
Furthermore, even if one were to grant plants some form of sentience, the argument still supports veganism: animal agriculture requires vastly more plant crops (for feed) than direct human consumption of plants. Going vegan reduces total plant “deaths” as well.
