One of the most
depressing stories of my adult life came from a phrase coined by the
environmental writer David Quammen in his 1998 essay “Planet of Weeds,”
originally published in The Atlantic
Monthly. Quammen’s argument was that habitat loss and degradation would
result in an earth made only of scrappy, adaptable, boring “weedy” species that
reproduce quickly and cohabit well with Homo
sapiens, the ultimate weed. We were on our way to becoming a planet of
generalists--rats, mice, cockroaches, pigeons, crows, deer, coyotes.
The
future as a dirt lot, the litter of fast-food and cigarette butts, grass poking
up through concrete foundations and the ground glistening with broken bottles.
A place where people drank. This was my private idiosyncratic image, this
planet of weeds, having bicycled or walked as a child past many dirt lots of
degraded soil and Russian thistle, a definition of ugliness I felt rather than
understood intellectually. No one at that time, in the mid-twentieth century,
told me these dirt lots were ugly and sad. No one pointed to the arboreal
majestic Sonoran Desert surrounding the sad, ugly, concrete sprawl of Phoenix,
Arizona and whispered: this is the Eden you left behind and from which you are
now barred by an angel carrying a fiery sword. No one needed to, I guess. It
was that obvious.

Like everyone
else, I grew up in a cultural conversation, with people whispering to me all
the time. Earth Day. Deep ecology. Bioregionalism. In the 1980s, my husband and
I were “back-to-the-landers” in rural New Mexico, wanting to root into soil and
sun, building our adobe house of mud, irrigating our way-too-big garden,
milking our quickly-too-many goats, having two homebirths—a daughter and
son--and too much goat cheese in the refrigerator. Our illusion that we could
live off the land lasted a few weeks, or maybe a little longer. Importantly, we
believed our personal connection to nature was meaningful. We believed we were part
of a new environmentalism and land ethic.
Meanwhile,
in the next twenty years, the cultural conversation become less about personal
connection and more about apocalypse. The Age of the Anthropocene had so begun.
The sixth mass extinction, ice caps melting, rainforests burning, a drumbeat of
doom. Our little experiment—how many onions could we grow and what would we do
with them?—seemed increasingly irrelevant. The deepening ties we felt to this
watershed, our love of these hills dotted with juniper and pine—all that was
nice. But the health of the planet lay in the greening of cities, where most
people live, and in changing the metasystems of commerce and law. Slowly we came
to the realization that we were not shaping the future. We had been left behind.
Which
wasn’t so bad. Every day, in the place where I live, I feel the shock of
beauty.
Clouds
massing and billowing, flat-bottomed
ships, cloud architecture, cloud turrets, cloud streets, weird streaks, wisps,
tails, cumulus, cumulonimbus, mamma, virga. Shafts of golden light. A purity of
light at the edges of a storm. Thunderclouds rising higher and higher. More
light, more billowing! A view so continuously grand and mystical that the mind eventually
loses interest and turns to something less extreme.
The
mourning dove, gray-cloaked, a little old-fashioned, a little Quakerly.
Formerly called the Carolina pigeon, this is one of North America’s most abundant birds. Where I grew up in the
suburbs of Phoenix, I often heard that plaintive coo-OO-oo…oo, oo.
Coo-OO-oo…oo,oo. Coo-OO-oo…oo, oo. I am not sentimental about the suburbs of
Phoenix. So I really don’t know why that coo-OO-oo heads straight for my
ribcage and builds a nest there. With the slightest encouragement, I can feel
weepy. Do we have some primal, aural attachment to mourning doves? Were we
twins in the Creator’s womb?
The
coyote. Their lives so secretive and
remote. We see a movement cross the road. We hear the distant chorus. We admire
the ubiquitous, assertive scat, and we think, yes, you are still here. We have
burned you alive. We have torn you apart. We have poisoned and trapped and
crucified you on fences. Your response is averted. The original aikido. You
slip through the interstices of home. You slip through the stories we
tell about you, on your way home.
I
run those same trails, on my way home, into the future. I run by hills that
rise like brown wings, overgrazed for a century, a grassland dominated by
mesquite and snakeweed. I run along the river running through my valley, sometimes
a trickle, sometimes dry, fought over by irrigators and developers and
environmentalists. I run through forests of ponderosa pine like a game of
pick-up sticks, black spars and jags. Turn in a circle. The entire horizon swept
by wildfires. And the aspen growing taller, scrub brush and locust, a new ecology
of plants and the animals who eat them and the animals who eat them. The fire
so sad and ugly to our eyes, the Earth under our feet so busy, busy.
I
don’t know how to talk about the beauty of where I live--where we all live, all
this land all around us, in the cities and towns surrounded by mountains and plains
and rivers and oceans, in the cities themselves with their clouds and mourning
doves--without sounding complacent or ignorant or autistic. As if I don’t feel
the grief. The anger. The fear. Does celebrating what we have mean we stop holding
on to what we are losing? So, shush about all that beauty. Don’t you see—how it
is being taken away?

My optometrist
wouldn’t know a bedside manner if he had just put his book and reading glasses
on it. He looks at one of my test results, does a double take, and says, “Oh.
Okay! You have myasthenia gravis, an autoimmune disease. This is serious.
People die.” He goes on to explain how nerve cells release the molecule
acetylcholine which opens a protein called an acetylcholine receptor (another
sodium channel) in a nearby muscle cell which then starts a biochemical process
that signals the muscle to contract. In myasthenia gravis, the body’s immune
system has mistakenly produced antibodies that interfere with this
process--specifically with the acetylcholine receptor. Typically, the disease
affects muscles that control the eye and eyelid, face, and throat. My symptom
is double vision. But I might also start having trouble swallowing or eating or
breathing.
Time
in this small brightly-lit office has become a kind of clear gel, viscous and
slowing movement. This is it, I think slowly. From now on, there will be my
life before this moment and my life after. Simultaneously, a part of me is
distracted by amazement. All that acetylcholine being released right now, all
that opening and closing, opening and closing, muscles contracting, eyes
seeing, throat swallowing, heart beating. So many trillions of molecules doing
just what they are supposed to do.
Later
I learn that myasthenia gravis, “once a uniformly disabling and even fatal
disorder,” can now be managed effectively with drugs. Likely I have ocular
myasthenia gravis, confined to the muscles in my eyes, and maybe—in any
case—the symptoms will continue to be mild or even disappear. That, at least,
is my professional opinion. I push this to the bottom of things I worry about
in the middle of the night, and since that kind of night-worry is tediously
repetitive, I never get beyond the top two items.
I
do occasionally find myself in conversation with protein receptors in my left eyelid.
In response to acetylcholine, these bulbous shapes allow positively-charged
sodium ions to enter cells which triggers the internal release of calcium ions
which creates an electric current which results in movement. I have become the
acetylcholine whisperer. Go, go, go, go, I say to the sodium ions. Sweetheart,
I encourage that receptor. You’re doing great. Pay no attention to those
antibodies.

Sacred datura--also called jimson weed, also called devil’s weed, also
called angel’s trumpet--has a large funnel-shaped, star-pointed lavender-white
flower with a sweet powerful scent. This is the flower you might conjure in
wizardry school if you were given that assignment: make a flower. Make
something from a fairytale. Make something seductive, glamorous, sexy. Make
something to make someone stop in her tracks and fall to her knees. Well, that
would be Datura wrightii. Typically, the sprawling perennial forms
mounds of blue-green leaves with a dozen blossoms opening in early evening and
on cloudy days. Adaptable, scrappy, and not often attacked by insects and other
herbivores, this weedy species likes disturbed landscapes and warm weather.
Every part of the plant--leaf, petal, seed, root--is poisonous.
The chemicals in datura inhibit the transmission of
acetylcholine. Your pupils dilate, your eyes are sensitive to light, your
vision is blurred. Your skin is dry. Your heart is beating too fast. You can’t
urinate. You have high blood pressure. Or you have low blood pressure. You may
go into a coma. You may die. You may be highly agitated. You are probably
delirious.
Because amazing, hard-working, best-friends-forever
acetylcholine doesn’t just activate muscles. In the brain, the chemical moves,
flows, quantumly entangles throughout the neural networks, specifically related
to how we remember, pay attention, and make decisions. Those activities require
a certain single-mindedness. They require suppressing other cortical activity,
turning down the volume, in which acetylcholine has a crucial role. The absence
of acetylcholine means you are being flooded instead with sensory and mental
noise: memories, fantasies, subconscious images, unconscious images, and real
life, too: information cross-wired, startling, leaping, pouncing, jumping,
speeding through the tunnel of language, the dirt of words, lost in the
silvery-buttery moonlight with a bright red scorpion like a Chinese dragon and
a great stinging tail…
Unsurprisingly, people have long used datura as a
source of visions and shamanic travel. Since the genus of datura can be found
throughout the temperate and tropical world, the list of cultures flying to the
moon on datura is a long one. For millennia, and for many of us, datura has
been a spirit helper. Datura teaches. Datura lets us see the dead. Datura makes
us lucky in gambling or finds a lost item or protects us from evil. Datura can
heal us physically as well, curing a range of ills from asthma to skin rash.
Certain kinds
of hallucinations seem specific to the suppression of acetylcholine. Often you
see and hear people who are not there but uppermost in your thoughts. In parts
of Mexico, the plant is called “husband-corrector,” and a woman suspecting that
her husband has a mistress will sprinkle datura into his meal and observe who
appears in the resulting delirium. If the wife is angry enough, she will
sprinkle a lot of datura.
In summer and fall, my heart always lifts at the
sight of these extravagant flowers. I think this actually happens: something in
my chest moves. On its part, jimsonweed is clearly relational. Jimsonweed wants
to be seen, admired, adored. Jimsonweed has something to say to me, and if that
is my unconscious talking, then why not listen?

David Quammen’s
essay can still be found on the internet although I barely have the attention
span to finish it now. For that I blame the internet and perhaps aging, too,
perhaps a lack of acetylcholine, something about protein receptors, something
about sodium ions.
I’m
sixty-two years old now, extinction around the next big corner. Everything is so
much more and so much less than what I thought it would be when I was a child. Slowly
I am learning to love my flawed and doomed life, my very own life, which is
full of miracles every nanosecond of the day. Slowing I am learning to love
this planet threaded, woven, stitched with our stories, this wilderness of mourning
dove and coyote, this rolling wilderness outside and inside, the wild
landscapes of the body. This planet of weeds, this drumbeat of mystery, this
radiance in the darkness. This planet that is so much a part of me that I
cannot really tell you where it ends and where I begin.
