Today Marshmallow reviews The Light Eaters: How the Unseen World of Plant Intelligence Offers a New Understanding of Life on Earth, a 2024 book by Zoë Schlanger.
Marshmallow’s Quick Take: If you like reading, then this is the book for you!
Marshmallow’s Summary: Generally, I tend to read fiction. As a result, most of the books I review here are fiction. However, this book was uniquely written and exists somewhere between the two. While it is completely centered on science and factual reality, some of the things I learned from it were so wonderful that I wonder whether we need fiction at all when nature has already provided us with such beautiful truths. (Sprinkles told me that this made her think of something the famous physicist Richard Feynman said: “I think nature’s imagination is so much greater than man’s, she’s never going to let us relax.”)
The book starts off with a modest introduction of the central question—are plants conscious? As such, the title of the first chapter is “The Question of Plant Consciousness.” The other chapters are as follows: “How Science Changes Its Mind,” “The Communicating Plant,” “Alive to Feeling,” “An Ear to the Ground,” “The (Plant) Body Keeps the Score,” “Conversations with Animals,” “The Scientist and the Chameleon Vine,” “The Social Life of Plants,” “Inheritance,” and “Plant Futures.” In each one, Schlanger focuses on a different aspect of plant life and delves into how it relates to the central question.
I’ve already been one to tend towards animism, and I did not have a difficult time considering the idea of plant consciousness; on the contrary, I found it enthralling. I loved how each example was so fantastic yet grounded in solid fact. One particularly striking example case Schlanger described was the emerald green sea slug. Ever since I read about it in this book, I have brought up this sea slug at every single opportunity I get (you’d be surprised by how many ways you can relate daily conversation to sea slugs and I’ve done them all). The slug is born brown and red, but immediately seeks out bright green micro-alga (basically, big and visible algae). It drinks up the chloroplasts, which are smooth and round circles, filling its body and turning it green. This process—with the slug’s transparent, tubelike tongue—looks just like drinking boba; this comparison delights me to this day! Then the sea slug somehow, wondrously begins to photosynthesize. While the sea slug is not a plant, Schlanger uses this creature to illustrate how the borders between animal and plant are not quite as defined as we might have once thought. This story was one of many fascinating facts I learned from this book. (It feels insufficient to say “facts” because they are more like revelations to me.)
Towards the end, Schlanger debates the nuances of what societal acceptance of plant consciousness would look like. She examines the wordings that botanists have used and would like to use. Perhaps new words and definitions will have to be made to help the public better understand that plant intelligence and / or consciousness is completely unlike those of humans or bunnies. The book ends in a rather abstract yet equally profound manner, leaving the reader wishing Schlanger had continued her marvelous writing.
Marshmallow’s Review: I think this might just be my favorite book. I did not finish it for the longest time because I didn’t want it to end. Each chapter revealed another beautiful part of nature and I felt constant awe, like one does when watching well-made documentaries.
I found Schlanger’s prose very different from what I’ve read from other writers. She writes the way that I feel she probably speaks. I don’t think she always used semicolons or other punctuation the way the standards of the English language demand; she used them more as tools to convey what she wanted. I know that this usage might bother some readers, and I was a bit taken aback initially. However, it did not counteract or undermine her words and her meaning.
I loved learning about what the world of plant and plant studies is like. Some recent events have made me start thinking about entering STEM a lot more. This book made me realize that science and the natural world has so much to explore and learn about. Regardless, I think everyone should read this book—even bunnies who don’t particularly like science. I think it raises and explores some very interesting and important questions about plants, their place on this planet, and ours. As concern for the climate becomes more and more critical, books that enlighten the public about the complexities of ecology are increasingly vital for social discussion. So, like I said at the beginning of this review, if you like reading or if you can read, then I would recommend reading this book with all of my heart.
