As a biologist, I can accept that consciousness exists in cats, dogs and other animals with sophisticated brains. During that time I also watched it respond to an injury to its trunk by sending out air-roots in search of new soil to re-root itself. In this episode, Captain Kirk beams down to a planet and finds a beautiful but empty metropolis. In subsequent years, the trees that had suffered through the drought consumed less water in the spring so that they had more available for the summer months. We recommend growing only tree species that are natural to the area. Human military forces destroy their habitat despite objections that it could affect the bio-network connecting its organisms. Back in real time, Spock and Dr. McCoy figure out that the strange buzzing is the hyper-accelerated conversations of aliens that exist outside normal physics. And the fungi in turn protect their host trees from attacks by other dangerous species of fungi and contamination by heavy metals. The Times was all but alone among top-tier outlets in framing this paper as a question of plant "consciousness." The tree has no leaves to create sugars, so the only explanation is that it has been supported by neighboring trees for more than four centuries. Forests create their own microclimate. We can also say that a tree can learn, and it can remember a drought its whole life and act on that memory by being more cautious of its water usage. Wohlleben: In about one in 50 cases, we see these special friendships between trees. Suddenly, Kirk notices that the movements of the crew slow down to a stop, as if time itself were being manipulated. Tweet; Plants are often thought of as inanimate objects, not living beings. They know that if you see such a couple, they are really like a human couple; you have to chop down both if you chop one down, because the other will die anyway. Like us, plants possess receptors, microtubules and sophisticated intercellular systems that likely facilitate a degree of spatio-temporal consciousness. Wohlleben: We have this essentially arbitrary caste system for living beings. Here in Germany, we have planted spruces to replace the beech trees. Trees make decisions. If trees lose their leaves too early, they many not produce enough food for a long winter. Some trees of the same species and age living right next to each other shed their leaves weeks before their neighbors. e360: You have also written that trees remember their experiences? Without your eyes, ears or other sense organs, you would still be able to experience consciousness, albeit in a radically different form. e360: Are there other ways that trees help each other? Even without thoughts, you would still be conscious, although the image of a person or tree would have no meaning. Wohlleben: We humans are emotional animals. To me, to consider the possibility that a plant might have consciousness seemed absurd -- until the other day. Trees in a forest of the same species are connected by the roots, which grow together like a network. e360: How so? Trees might not have the same sort of consciousness as us, but it is the perfect consciousness that is needed in order to flourish as a tree. By Richard Schiffman It is similar to industrial meat production where a pig, for example, is fed too much so that it grows prematurely and in five or six months it can be sold and slaughtered. I do get plants have a consciousness. Wohlleben: One thing is that mother trees suckle their children, they feed the young tree just enough sugars produced by its own photosynthesis to keep it from dying. July 03, 2017 | By Cassie Stiftl. That would be like a family where they shoot the parents to give the kids more space. Wohlleben: Yes, they are working well all over the world — in the Amazon, even in the U.S, some forest owners are working with these methods. When a person belongs with a tree, they also belong with its offspring: any trees that grow from the seeds of the first tree, no matter how far the seeds may scatter. In the forest I manage, students from Aachen University did a study that shows that the parts of the forest that grew naturally were 3 degrees C cooler than those that are managed and disturbed by humans. Light-stimulating chemical reactions in one leaf cause a chain reaction of signals to the entire organism via vascular bundles. This is why plants … BY STEHPEN HARROD BUHNER . But the problem is I was still thinking of trees as a commodity, as something to sell, not as living beings. Plants process information just as animals do, but for the most part they do this much more slowly. This suggests that plants are able to remember this information and modify their behavior based on environmental cues, “a form of learning [that] is ubiquitous in the animal kingdom.” These experiments raise questions of whether plants do have consciousness, and if so, how much or what it looks like. We have been viewing nature like a machine. The woodland has gone from a money-losing operation to a profitable one. These discoveries have led to “plant neurobiologists” to claim that “plants possess many of the same mental features as animals, such as consciousness, cognition, intentionality, emotions, and the ability to feel pain.” Of course, media love plant neurobiology, which got started in 2006. November 16, 2016. Because of this they argue plants are conscious. Their root tips have highly sensitive brain-like structures that can distinguish whether the root that it encounters in the soil is its own root, the root of another species, or the roots of its own species. Q. Hi, do plants have a consciousness? Indeed, you wouldn't be able to discern objects from each other, but rather would visually experience the world as a kaleidoscope of changing colors. We recognize them as marvelous beings. e360: You speak about trees as if they had personalities. Trees distinguish between one individual and another. Without your eyes, ears or other sense organs, you would still be able to experience consciousness, albeit in a radically different form. Also, in my childhood, I remember staring at the fire, and feeling as if it had consciousness and it was actually like a temporary existence or maybe a … Wohlleben: This one beech tree was cut four to 500 years ago by a charcoal maker, but the stump is still alive — we found green chlorophyll under the thick bark. If trees lose their leaves too early, they many not produce enough food for a long winter. In the past, those who have suggested that plants have senses, thoughts, and feelings have been labeled as hippies, tree-huggers, and crazies. This hierarchical ranking of living beings is totally unscientific. Scientists like Suzanne Simard [who teaches forestry at the University of British Columbia in Vancouver] have labeled this amazing web of communication the Wood Wide Web. Andre Kessler, the lead researcher, called this "priming its defense response." Do plants have … Not so, says biocentrism. A tree is conscious of its surroundings. e360: Social beings? Instead of generating a pattern of colors, the particles of light bouncing off a plant produce a pattern of energy molecules -- sugar -- in the chlorophyll in its stems and leaves. "Plants definitely have several different forms of memory, just like people do," said Chamovitz. In "Avatar," humans mine a lush moon inhabited by blue-skinned extraterrestrials, the Na'vi, who live in harmony with nature. Wohlleben was eventually hired by the local mayor to look after the same forest in an eco-friendly way. In an interview with Yale Environment 360, Wohlleben, author of The Hidden Life of Trees, discusses how trees are sophisticated organisms that live in families, support their sick neighbors, and have the capacity to make decisions and fight off predators. You can learn more about his work by visiting his website at www.robertlanza.com. He also has started a “living gravestone” project in which townspeople pay the equivalent of the commercial value of an ancient tree to have their ashes interred at its base. How did you first get interested in this topic? As I sat in the kitchen that day, the early-morning sun slanted down through the skylights, throwing the entire room into gleaming brightness. Green Hydrogen: Could It Be Key to a Carbon-Free Economy? The only trace of life is the mysterious buzzing of unseen insects. This kind of partnership is well known to foresters. e360: So the low-tech methods are actually more cost effective? If you need to flag this entry as abusive, The essential guide to taking care of your mind and body. The wood is also of lower quality, so the price we get for it is going down. In this way and others, tree friends take care of each other. If they keep them on too long, they may get caught in an early snowstorm and the weight of the snow can break their branches. e360: You tell one amazing story in the book about trees keeping neighboring stumps alive. e360: You’ve said that there are “friendships” between trees. I thought— “Wait, I am someone who wants to protect nature, and here I am being asked to destroy it!” I visited some other districts that were operating in an eco-friendly way, and I thought, that’s the way woods should be managed. Simard, it should be noted, has never claimed that trees possess consciousness or intention, although the way she writes and talks about them makes it sound that way. Consider your own consciousness. His latest book is a collection of nature-inspired poems entitled "What the Dust Doesn't Know." Is life in the slow lane worth less than life on the fast track? For the last several months I'd been watching it send up new fronds, which, since the winter solstice, have been repositioning themselves towards the shifting sun. If you only write technically about “biochemical processes,” people would quickly get bored and stop reading. • My irrefutable experience that trees (and rocks and water) do have consciousness… For more information on the Language of Energy, see my book, Multi-dimensional You, available or available right here on my website or through Amazon . Is that a good thing? Wohlleben: We know that trees also exchange information. Part of HuffPost Wellness. e360: How would understanding trees better change the way we manage forests? Trees are known to absorb negative energies and give back healing energies. Plant biologist Lincoln Taiz from the University of California, Santa Cruz, is both underwhelmed by Gagliano’s data, and quick to point out that plants simply don’t have the hardware for consciousness. Wohlleben: Humans are weakening ecosystems by indiscriminately cutting timber. We feel things, we don’t just know the world intellectually. "They have short-term memory, immune memory and … What is the evidence for that? Although I saw the movie three times, I still cringe whenever someone tells me that a plant has consciousness. They also, of course, don’t have brains, so they lack the machinery necessary to turn those stimuli into an actual experience. When we thin forests, the temperature rises, the humidity goes down, evaporation increases, and all the trees begin to suffer. It is conscious of light. Time isn't an object or thing; it's a biological concept, the way life relates to physical reality. They also exercise independent judgments, which can differ. If they grow too fast in the beginning, they will waste all their energy in the rapid growth and will be out of breath, exhausted, and die early. Wohlleben: Trees have just as much character as humans do. I’m not sure why some choose to do this earlier and others later, but it shows that there really are differences of character that we can’t easily account for. But the animals are unhealthy. Certainly, Says German Forester, Amid Tensions in Myanmar, An Indigenous Park of Peace Is Born, At Sea and in Court, the Fight to Save Right Whales Intensifies, How Small-Scale Loggers Can Help Save Africa’s Tropical Forests, As South Africa Clings to Coal, A Struggle for the Right to Breathe, Equitable Retreat: The Need for Fairness in Relocating Coastal Communities, Learning How to Talk: What Climate Activists Must Do in the Biden Era. Basically, the article argued that to lose consciousness, one must have consciousness—so if plants seem to lose consciousness under … That’s one reason most scientific research has so little impact on people. The Queen Sago tree and I were both "happy" the sun was out. Wohlleben: That’s right, we use horse-drawn carts to remove the wood. The climate becomes hotter and drier and the environment becomes worse for the trees that remain. Studies show that dogs have a level of intelligence -- and consciousness -- on par with a two- or three-year-old human child. It is now too dry and warm for spruce, so those forests are failing in large parts of our country. Just today, I saw two old beeches standing next to each other. Some argue that plants may have awareness and intelligence, while detractors persist. Wohlleben: We all learn in school that evolution advances by pitting each individual against every other in the struggle for survival. But after joining a German forestry agency and managing a community forest, he soon became disillusioned with practices like clear-cutting, chemical use, and mechanical harvesting that put short-term profits before sustainability. e360: Can foresters help protect forests from climate change and other environmental threats? Do plants have souls? Therefore, it is recommended to regularly spend […] I always ask people, “Who would think of, say, elephants in such terms?” We don’t look at elephants just as commodities or as mechanical and insentient objects. Even trees and other plants have consciousness, which emanates in the form of vibrations and energies. I made this discovery myself, and later learned that other foresters have observed this happening as well. Contributors control their own work and posted freely to our site. I see that is why when people sing or talk to their plants, the plant actually grows better. Flies and insects have eyes, so they are a bit higher, but not so high as monkeys and apes and so on. We think of time -- and thus consciousness -- in human terms. I had to learn from the people of the community where my forest is located how to take a closer look at trees, to see them as unique individuals. Wohlleben: Trees have just as much character as humans do. Science often takes these words out, but then you have a language people can’t relate to, that they can’t understand. Natural systems, with a variety of species, are much more resilient. So trees have a stake in supporting one another to keep all members of the community healthy. As a young forester I was told to make clear-cuts, to use insecticides, and so on. Obviously trees don’t have brains, but some believe that trees may have something akin to a nervous system and produce some of the same hormones that animals do. e360: How do the healthy trees that feed their sick companions benefit? Then I remembered the episode of "Star Trek" called "Wink of an Eye." The trees pay for this service by supplying the fungi with sugars from their photosynthesis. Indeed, the sundew plant (Drosera) will grasp at a fly with incredible accuracy -- much better than you can do a fly-swatter. But as I’ve said, faster growth makes trees less healthy and more susceptible to illnesses. The scientific consensus is that plants do not have the kind of cognitive faculties necessary to support a consciousness that includes things like self-awareness, theory of mind, or complex emotions. _____Yale Environment 360: You write in your book: “When I began my life as a forester, I knew as much about the hidden life of trees as a butcher knows about animals.” Peter Wohlleben: Forestry students are taught how to harvest wood, what machines to use, how to sharpen the blade of a chainsaw, how to sell the timber, what price to expect — that’s about it. But the majority of plant scientists would, I think, agree that to draw any conclusion about “consciousness” from this experiment, as the Times would have us do, is tricky at best. Wohlleben: We are told that forests and woodlands need management, but it is just plantations that need management because they are unstable systems that can be destroyed by storms, by insects, by fire. Trees should grow very slowly in the first 200 years, which we can call their youth. The feathery creature, there in my conservatory, responded to the environment much like a primitive invertebrate.
