We all cut down plants, for varying reasons. Like all living beings they have potential to feel pain. But when harmed, do they feel pain?
You would probobly be better off posting a question like this in the philosophy forums but I will give it a shot. Pain, as you and I see it, is not just a physical reaction to outside stimulus. While plants do in fact react to outside stimulus they have no brains to process the consequences of that stimulus. Therefore, they are not "feeling" anything they are simply reacting to an outside stimulus. In other words, plants are not "living beings" they are living but they are not beings.
