00:00:30.000This is Radio 314 on the Red Ice Radio Network.
00:01:00.000And there are times when I'm pleased and then there are times when I cringe, regret it, don't want to release the interview.
00:01:06.420So this time around, we'll be discussing plant intelligence with Stephen Harrod Buhner, who's the author of 19 books, including Plant Intelligence and the Imaginal Realm, The Lost Language of Plants and Sacred Plant Medicine.
00:01:18.840He has taught for more than 30 years throughout North America and Europe.
00:01:22.400Can the subject of plants become political?
00:01:29.800Well, you've written 19 books revolving around plants.
00:01:33.040So how did you come to study the realm of plants?
00:01:36.800Well, my great-grandfather was a physician who primarily used botanic medicines.
00:01:43.700He started practice in 1911, and they didn't really have many pharmaceuticals then, and I spent a lot of time with him on his farm in Indiana, and that's sort of what oriented me toward the healing professions and wanting to do something more kind of old-fashioned, I guess you might say, and not so technological.
00:02:05.640And then just with the whole human potential movement that happened in the 60s and 70s and kind of the development of massage therapy and different psychotherapeutic techniques and all of that.
00:02:19.480And then eventually, in the early 80s, I wandered into herbal medicine, and it was just a great fit for me.
00:02:27.880Well, James Lovelock was the scientist who first theorized that our planet is a self-regulating biological entity, which is known as the Gaia Hypothesis.
00:02:36.520However, I'd say this concept of Mother Earth has been in the psyche of our European ancestors for thousands of years, but today we can have a deeper understanding of it.
00:02:44.380So share with us the concept of plant intelligence.
00:02:48.400Well, the fascinating thing about Jim Lovelock's work is that he was showing that there is this kind of livingness in the world that we'd really been taught for a long time that wasn't there.
00:03:03.520And, you know, we've been trained in the West to pretty much look at the world around us as a static backdrop, you know, and human beings are kind of the only intelligent actors.
00:03:14.360that are sort of walking across that stage, but that was never really very accurate.
00:03:20.840It really came out of 19th century thinking and early 20th century thinking, and it turns out that what people call non-linearity or chaos theory,
00:03:32.320the tendency for biological organisms to sort of self-organize, which Gaia is the largest example of that, is extremely pervasive here.
00:03:42.740And every time that happens, the organisms have to be able to do a lot of things.
00:03:48.860They have to be able to tell the difference between me and not me.
00:03:51.920They have to be able to tell the intent of an organism that's coming toward them.
00:03:57.540They have to be able to craft responses, all of which is highly intelligent behavior.
00:04:03.880And it turns out literally every biological organism on the planet is really highly intelligent.
00:04:11.040Human beings are in some ways much less intelligent than some of those entities.
00:04:16.880So when you start looking at bacteria and plants, for instance, what you start finding is this tremendous intelligence level
00:04:26.160with extremely sophisticated neural networks like we have in our brain, and they're able to do all of those things, plus a lot more.
00:05:23.400They can't call, you know, go to the hospital or whatever like that.
00:05:27.160They have to craft all of these responses, and they're really good at creating sophisticated chemicals to do so and to coordinate and communicate with everything around them.
00:05:43.300Well, let's talk about the plant brain because you write about how brains don't actually have to look like the human sense of the word, right?
00:07:47.000Yeah, there's a plant bell curve just like there is amongst human beings.
00:07:51.480But it might even be more accurate to think of it looking at human beings as just being part of the mammal species.
00:07:59.920And you're going to get a range of intelligence or a range of sophistication of neural net might be a better way to put it across the whole mammal spectrum.
00:08:10.280And you're going to find that same thing among plants.
00:08:13.120Some have massive neural networks, like that aspen tree system that I just mentioned.
00:08:19.400Others, like a single rye plant, will have about 16 billion neurons.
00:08:43.700I mean, they're the oldest life form on the planet.
00:08:46.680So, you know, they've been around somewhere between three and a half and four billion years.
00:08:52.080And what they have is they have really sophisticated neural networks that they've developed that look different than a plant or a human neural network.
00:09:01.460But they perform exactly the same function.
00:09:03.960And so what happens with bacteria, they sort of all hook together almost in a superorganism.
00:09:10.380You might call them a swarm intelligence in which the neural network capacities of a single bacterium hook together with all of the others.
00:09:19.380And you get this neural network that there is nothing on the planet that is larger than that particular neural network.
00:09:26.520And many people have remarked that those bacteria, if you touch bacteria in one part of the earth and do something to them, that information will travel around the planet extremely rapidly.
00:09:42.920And that's one of the ways they started figuring out that they're more like a global superorganism rather than isolated individual entities.
00:09:50.520Wow. Well, what is your take on the bacteria relationship with us?
00:09:56.340Does the virus host relationship offer any benefits?
00:09:59.240Well, the interesting thing is if you look at Lynn Margolis' work, I mean, you know, all of this stuff I like to continually say,
00:10:07.640all this stuff we're talking about is information that's been carefully concealed in peer review journals where most, you know, researchers can't find it.
00:10:15.960You know, so the thing is, like, when you look at Lynn Margolis' work, she worked with bacteria for all of her life.
00:10:23.080And she was the one that began to realize that all complex biological organisms were simply bacteria that had morphed into a more sophisticated shape,
00:10:37.680innovated from a process she called symbiogenesis, where two organisms that are unlike each other merge and form a completely third organism
00:10:47.860that has the capacities of both of the original ones and other ones that can't be predicted from studying those first ones.
00:10:56.080And so, you know, and one of the things she continually said is bacteria are our ancestors.
00:11:02.100They invented consciousness. They invented neural networks.
00:11:05.580So when we attack bacteria, we're engaging in this kind of form of self-hatred.
00:11:10.000You know, but even if you look at it more reductively than that, the surface of our body is covered with bacteria.
00:11:18.160Our GI tract is covered with bacteria. We've evolved with them.
00:11:23.080And if they were removed from our bodies, we would die pretty much immediately.
00:11:28.140Without that sort of collaborative behavior, our life, no advanced life or more complex life form could exist.
00:11:37.680Oh. Well, if we talk about invasive plants, they obviously have a function.
00:11:43.100So what can you tell us about the purpose of invasive plants as we know them?
00:11:46.940Well, the thing is, you have to understand plants have tremendous power of movement.
00:11:50.480Nobody can really quite figure out how plant populations move across the world.
00:11:55.280But every time they do mathematical analysis of it, they don't move by random dynamics.
00:12:02.240There's really sophisticated, nonlinear periodicity, they would say, going on.
00:12:09.060And so, you know, the Earth moves on much longer timelines than we're used to.
00:12:14.720So the fascinating thing about invasive plants, they, you know, were sort of taught that somebody brought the seed back.
00:12:23.660It was on their shoe when they went to, you know, Belgium or something.
00:12:27.720And they bring it back to the United States and then start to spread.
00:12:30.800But really, when you really look more deeply into it, you start seeing that the plants that move into particular areas all do so for specific reasons.
00:12:39.640They're actually counteracting long-term ecological damage in that location.
00:12:44.820And they begin to rectify the problem by being there.
00:12:49.600And after a while, they'll move on and other plants will come in once the soil is restored and the ecosystem is more balanced.
00:12:57.060Now, a great way to get an idea of this, because I know about plants best, but when you look at the zebra mussel,
00:13:05.420which is something everybody keeps bringing up, is this horrible invasive pest.
00:13:08.600It's in the Great Lakes system in the United States.
00:13:13.020And so it's really incredibly fascinating to me, because the Great Lakes are tremendously polluted.
00:13:20.620And they've killed off a lot of the natural life that lived in there for thousands of years.
00:13:26.380And one of the things that began to die off or began severely reduced in numbers were all of the normal mussels and oysters that lived in that location.
00:13:37.360Plus, they built all these huge industrial plants around the Great Lakes, which continually polluted them.
00:13:45.440So they're not actually very healthy places.
00:13:47.500Well, when the zebra mussels moved in, one of the functions of mussels and oysters, for instance, is they filter the water.
00:13:56.300A single zebra mussel can filter about three gallons of water per hour.
00:14:02.140And so you get these millions of zebra mussels who are in there that are acting as a massive filtering mechanism to clean the lakes.
00:14:09.380But secondly, the one thing that they really like to do after that is clog the intake ports and the exit ports of all of these industrial factories.
00:14:20.020So they're screwing up their plumbing system, stopping them from being able to continue to pollute.
00:14:25.740So that's why I say that whenever you're looking at an invasive species, you have to ask, what's its ecological function?
00:14:34.100And invariably, you find that they're doing something to correct an underlying ecological disruption.
00:14:41.020Yeah, many people think that dandelions are weeds just to be mowed down, but they're shining their little yellow faces at us, begging to be picked and consumed, because they're also highly beneficial for humans.
00:14:51.480I mean, I always have dandelion tea in my house.
00:14:56.300It grows in ditches and around old barns and cars.
00:14:58.720It's also great for medicinal properties.
00:15:00.860Yeah, they're two absolutely great plants for healing disease, and you start to see these growing in certain locations.
00:15:11.720But dandelion is extremely good for liver problems, which a lot of people suffer from.
00:15:16.900Nettles are really good as a tonic for people that are really run down or they're nutritively diminished somehow.
00:15:24.640And so it's always really important to look at what these things are doing and to understand that, you know, there's a lot more going on out in nature than we've been led to believe.
00:15:36.340I mean, we just don't notice how incredibly wondrous it is.
00:15:49.780Well, as a friend of mine said once, she said, it's their journey too.
00:15:55.080And I love thinking about it that way.
00:15:57.060When you really start getting into plants and human beings and you start looking at it, there's this terrible suspicion that begins to emerge, this dawning realization that's really hard to put down after years of looking at it, that human beings serve as plant propagators.
00:16:18.560I mean, we're the ones that carried them all around the earth, and you have to understand, plants are tremendously older than human beings, anywhere from 140 to 700 million years, depending upon what you're looking at, what your criteria are.
00:16:34.120And they and bacteria are the two most fundamental organisms to life on earth, the way the whole earth ecosystem is, couldn't be here.
00:16:46.140If all the bacteria died, everything else would die.
00:16:50.540If all of the plants died, the bacteria would still be here, but human life would cease to exist extremely rapidly.
00:16:58.040So they're much more fundamental to everything here than we are.
00:17:01.940We're sort of Johnny-come-lately-after effects, in a sense.
00:17:06.600And they, so because of that, we were sort of emerged into an existing system.
00:17:13.900And one of the things, the major things plants get from us is we move them around the earth and help distribute their seeds.
00:17:21.780I mean, it's more like we're the dog and they're the person walking us.
00:17:26.080So do you think humans serve an ecological function on the planet?
00:17:30.640Yeah, I think humans, you know, that's one of the things I talk about in the book,
00:17:34.220that I think humans serve a really important ecological function.
00:17:38.980And, you know, I've been working on that, thinking about that for about 20 years.
00:17:44.980The whole concept that human beings are a plague on the earth or a cancer or a virus,
00:17:51.440I'm sure you've heard that and a lot of people listening have heard that sort of phrasing.
00:17:56.480And it just never really sat well with me.
00:18:00.100I mean, it's a great way to, you know, sort of give energy to feelings of guilt,
00:18:05.520but it didn't really seem to serve any function.
00:18:09.100And if you look at the Gaia hypothesis, the earth is a living, intelligent, aware organism,
00:18:15.700it would be really strange for an organism that's 4 billion years old to make that kind of an error in judgment,
00:18:23.460to generate an organism which was going to destroy the very biosphere itself.
00:18:28.980So I started looking at it with new eyes and really asking what's the ecological function.
00:18:37.380And what's really fascinating is that if you start looking at sexual reproduction on the earth,
00:18:43.120I mean, that's one of the things the earth loves.
00:18:45.460The earth is engaging in sex all of the time.
00:18:48.940Sex, drugs, and rock and roll is ecologically fundamental to the functioning of the planet, actually.
00:18:54.340And so then if you start looking at the innovations, Gaia, I think a better word for evolution is actually innovation.
00:19:04.180Gaia is always innovating and Gaia is always creating more complex ecological structures
00:19:11.260because the more complex they are, the better able they are to respond to perturbations
00:19:17.080and their functioning like asteroid strikes or something like that.
00:19:21.380So one of the things Gaia does to keep everything really healthy is blending genomes all around the planet.
00:19:29.720And about 140 million years ago or so, Gaia started getting really interested in split gender sexuality.
00:19:40.800Gaia had been playing around with that for quite a while, maybe 700 million years, something like that.
00:19:46.020And then that was a really great innovation.
00:19:49.460You start looking at how plants propagate, you also get this, first they had wind pollination, that was the earliest form.
00:19:58.920And then with the emergence of flowering plants about 140 million years ago, Gaia had this even greater idea,
00:20:07.080which was you get the pollinator to take the pollen exactly where it needs to go rather than relying on the wind.
00:20:13.780And you combine that with Lynn Margolis' understanding that there were just four original bacteria that gave rise to all of the organisms on Earth.
00:20:25.080And then you start looking at what human beings have done.
00:20:27.920Now, human beings have done a very similar thing that plants do.
00:20:32.740The plants store up all of this material over the winter and then in the spring and then the summer and then in the fall they start putting out seed.
00:20:43.120And they use those stored resources to create seed stock, which they then release into the world to propagate.
00:20:50.180So Richard Dawkins said this thing once, he said, Gaia's not alive because Gaia doesn't reproduce.
00:20:58.180And I thought, well, that's a really strange thing for an 80-year-old person to say about,
00:21:04.140or somebody that's going to live 80 years to say about an organism that's 4 billion years old.
00:21:09.240How would he know if Gaia only reproduces every million years, for instance?
00:21:13.180So the thing is, is that as we create all of these rocket ships and everything and send them out into space and all of our space probes,
00:21:23.280they're covered with bacteria and we're actually sending them out into space to all of these different planets.
