The study of plants and other lifeforms on the planet is shedding light on concepts that were already known in our ancient world. Everything on our planet is alive. Just because it is living in a different form than we are, and has different biological processes than we do, does not mean that these lifeforms do not possess consciousness or that they cannot think, feel, and react.
If you told somebody that plants can feel pain, you might think they are nuts, but the truth is – an enormous amount of research has been conducted by plant scientists, and much of it clearly shows how plants have some remarkable abilities to react to and sense the world around them. Some plant scientists insist that yes, plants are intelligent, they learn, remember, and again, react. So, it’s not far off to suggest that they might even feel pain. There are also studies suggesting that plants can learn from experience.
“They have ways of taking all the sensory data they gather in their everyday lives… integrate it and then behave in an appropriate way in response. And they do this without brains, which, in a way, is what’s incredible about it, because we automatically assume you need a brain to process information.” – Michael Pollan author of “The Omnivore’s Dilemma” and “The Botany of Desire” (source)
