No, the statement “plants have feelings too” is not a scientifically sound argument against veganism. So far, there is no convincing evidence that plants are sentient. While plants are living beings and react to their environment, such biological reactions are not equivalent to conscious experience.

Are plants living beings?

Yes, plants are living beings. They grow, metabolize, and reproduce. However, plants and animals differ in their biological organization. Most animals possess a nervous system with which they process information. In contrast, plants have neither nerve cells nor a brain or any comparable central nervous system.

Nevertheless, plants can register and respond to stimuli such as light, touch, or injury. For example, they can change their direction of growth, produce chemical defenses, or emit warning signals to neighboring plants. This shows that plants can carry out complex biological reactions. However, it does not prove that they consciously experience these stimuli.

Do plants have feelings and can they feel pain?

A reaction to a stimulus is not the same as the sensation of pain. Pain in the subjective sense refers to an unpleasant conscious experience. In animals, there is ample evidence that they can feel pain. This includes, among other things, their nervous systems, their behavior, and their reactions to pain-relieving substances.

In plants, on the other hand, there is no sufficient evidence of sentience according to the current state of scientific knowledge. Even the ultrasound noises emitted by stressed plants, often referred to as "screams," are no evidence of pain sensation (study on ultrasound sounds).

Plants are living beings - does that speak against veganism?

No - the central distinction is: Being a living being is not the same as being sentient. What is decisive for ethical consideration is not just whether a being is biologically alive, but also whether it can have its own interests and, for example, experience suffering or well-being. For many animal species, there is scientific evidence of sentience. For plants, there is no convincing evidence to date.

What if plants were sentient?

Let us engage in this thought experiment: Currently, large quantities of plants are fed to so-called "livestock." If humans were to consume more suitable plants directly instead of feeding them to animals first, a significant portion of cultivation could be eliminated.

Studies on global land use show that a more plant-based diet could significantly reduce the demand for agricultural land. Even under the hypothetical assumption that plants were sentient and plant suffering should be avoided, there would be strong arguments for consuming plants directly rather than feeding them to animals first.

Conclusion: Do plants have feelings?

Plants are living beings and react to their environment. However, according to the current state of scientific knowledge, there is no convincing evidence that they consciously experience feelings or pain. The statement “plants have feelings too” is therefore not a scientifically sound argument against veganism or a plant-based diet.
