Gifts From The Sea

Talking with a new friend the other day, I mentioned how much I enjoyed the Florida lifestyle and how amazing it was to be able to live outside most of the time. The air is so clean, even though many of the cars here are “super-sized” – from full-sized 4WD Ram trucks to Cadillac Escalades and Range Rovers. The incredible amount of plant life here must help to clean the air. I’m not so sure about our canals and the rivers and bays, but over time, I expect I’ll find out. There was a manatee in our canal this morning.

So, from a health and beauty perspective, it’s really easy to take care of skin here as long as you stay away from noseeums and mosquitos. The humidity may make my hair curl but I don’t care. You have to use sunscreen because the sun is so strong here, but again – it’s easy to do and worth spending what you can to get good mineral sunscreen. (Note: don’t use the cheap stuff for a lot of reasons – the chemicals are associated with cancer, they seep through your skin, and if you go in the water at all, they are toxic to fish and coral and other living creatures).

 

You get up and you’re sweating … you get out of the shower and you’re sweating …

LOL no! I just got in from a run.

Which brings me to clothes and makeup. You know, all sci-fi writers have abiding interests in clothing and makeup.

Welp – you don’t need many clothes here in SW Florida and there’s little point in makeup. You will sweat it off. If you put anything on that’s going to stay on, it will be so harsh and garish that it will look awful. The less, the better. Now that I have my hair back again, I am so happy. I didn’t cut my hair for a long time because, when I started, I was actually trying to save money. Then over time it became “How long can I grow it?” Of course it’s not my style. Glad to be “me” again.

So enough about me. On to the coyotes of Sanibel Island. And a story about a book I’ve looked in many times, but never read. The reason we are in Florida is that I had complained several times to Bruce how sad and depressed I was that there seemed to be no shell left on any California beach. I think it had been at least five years since I’d found any notable shell on any beach, anywhere up and down the state. Maybe in July or August of last year, we even went to Silver Strand State Beach which is south of Mission Bay and noted for shells (supposedly), and I was able to find only one sand dollar in a 3.5 mile walk. You still cannot find anyone openly discussing the lack of shells on beaches in Southern California (and Central Coast and northern beaches). It’s clearly a result of climate change. When we went fishing from Dana Point shortly before we left, the guys on the boat talked openly about how dirty the water was. Before we left, we started to see commercial fishing offshore, which hadn’t been seen close to California beaches for years. And the smog had been creeping in, stunning to see after years of cleaner air and so much effort. Environmental badness all-round.

So, in January, we flew to Sanibel Island and stayed for a week. Not only did I mail two big boxes of shells home, I left these shells with our neighbor Elizabeth when we moved. There are more than enough shells here that they seem to be an endlessly-renewable resource. Judging by spring and summer here, winter seems to be a little better shell season than these times, but I’ve picked up a few treasures. Bruce and I even got two “grandpappy” shells while touring the Everglades in January – a massive lightning whelk and a fighting conch – both at least 8-10 inches in length.

Not long after we returned to Southern California, we were looking at places to move to along the southwest Florida coast. And we left – nearly the last day that we could, I think, during the first part of the COVID-19 crisis. We drove cross-country March 26-March 30.

Sanibel and Captiva Islands are a little south of where we are now in Punta Gorda. They are world-renowned for the beauty of their shells and their preservation of unspoiled nature for wildlife. A large part of Sanibel is the J.N. “Ding” Darling Nature Preserve. Both islands have not allowed high-rise development, and there’s ample open space as well as, on Sanibel, the extensive “Ding” preserve and wildlife area. It is a haven for birds, fish, dolphin, you name it. If you have ever wanted to see a roseate spoonbill, “Ding” is one of the places to go. If you love seabirds, you will see every type you can imagine at “Ding.” Also, wear bug spray.

So, when I was growing up, my grandmother, the renowned and feared “Nana,” had a few favorite things, one of which was a slender, beautiful volume, Gift From the Sea, by Anne Morrow Lindbergh.

Growing up, I often looked in this small book, and I suppose I read a little of it, but what I mostly did was gaze at the delicate drawings of shells which were its illustrations. I thought it was about the ocean; little did I know that now I was re-acquainted with it by a lady on Sanibel — it was about this lovely woman’s ideas of where a woman should go, and each chapter, inspired by a shell that she had found while staying on, not Sanibel, but the smaller, more northerly companion island, Captiva. Captiva is today, the demesne of rich people’s mansions, a couple of resorts, and the awesome, retro, down-to-earth Jensen’s Marina. Oh – and the beach at the end of the road is very nice – but there’s no such thing as “not a nice beach” in Southwest Florida.

Yes, I found where I should be by haphazardly visiting the island where a woman my grandmother deeply admired, Anne Morrow Lindbergh, had written a beloved book about women finding their way in life. Through shells.

We are so out of touch with nature, I think, that such things seem novel — strange — unusual. A shell seems to us to be a magical thing, but perhaps ever it was so.

So we took Gambit to one of the beaches on Sanibel last week (Algiers Beach, I think).

I think this is Stump Pass Beach but … hey … that’s the Gulf of Mexico.

Driving back, we weren’t far from the “Ding” Darling Preserve when Bruce said, “What’s that in the road? A deer?”

“It’s deer-colored,” I said. But as soon as the fairly tall, rangy animal moved, we could tell it was no deer.

Hm. What is it?? It was almost fox-like in coloring, but far too tall to be a fox.

Probably too hard to see from this sad attempt at blowing up the picture, but it was a very dark and sleek looking, tall, rangy coyote. He ran in front of our car, glancing back over his shoulder at us, then disappeared into someone’s property on the other side of the road. As soon as he looked back, I knew from his yellow-green eyes he was a coyote.

Yes, there are coyotes on Sanibel Island, between 25 and 30 of them. They have only been there since 2012, or so “reports” say.

Before we left Laguna Woods, our much smaller, sandy-colored So Cal coyotes were boldly trotting in twos and threes throughout the neighborhood, looking for stray 3 pound Yorkies or elderly cats to gobble.

With eyes and ears open here, there are so many animals to see and so many beautiful plants. Just — bug spray.

I now have a book that I need to read that I should have read years ago — it is among the hundreds I left behind or gave away before we moved. Did you know that at one point, I had 5,000 books? No? Oh, well — they are all gone to good or bad or no homes now.

Now I pick up shells on the beach, but seldom keep them. I have a tiny collection of orange and red scallops. I keep them in a tiny porcelain dish with a miniature sea turtle in it that I bought for Bruce this past Christmas. Small and light, I saw nothing wrong with taking this dish with us to Florida.

Every day it seems, comes a new revelation, a change of feeling, a different insight.

Jogging with Gambit earlier, we saw Big Boy, the massive Muscovy duck who must surely outweigh Gambit’s 11 pounds, heaving his bulk across Marion Ave. near the teenage alligator’s pond. Big Boy has improbably grown even fatter in this heat and seems to do little except shuffle between the two ponds throughout the day. He held up a number of cars on his journey, and was so lazy that as we passed, the best he could do as he lay in the damp grass under an elderly oak was mouth vague warnings through his gray/white/red mottled bill.

The evening is soft now and the westerly sun is casting its long rays through the lanai shutters. The sun stays strong here even in the late afternoon, right into sundown.

I think of the beautiful, fine-boned Mrs. Lindbergh walking along Captiva’s shores. Hurricane Charley came in 2004, one of the strongest ever to hit the U.S. So she may well have walked between Captiva and North Captiva — the hurricane cut a channel between the two islands, and North Captiva can now be reached only by boat, like a lot of places here.

I see her bend to pick up a shell; I could never associate the awkward “Sanibel Stoop” with such a lovely woman. I think of the quiet lives of the imagination these women must have lived, for I feel her in my mind as I see my grandmother, and as I see Eleanor Roosevelt. Their lives ever so much freer than so many womens’ yet still, so very unfree. From their clothing to their hair to what they could say, they held their innermost thoughts to themselves. But then shell by shell, Anne Morrow Lindbergh wrote her Gift from the Sea.

So many things, our culture has taken from us, from our ability to be kind to each other and accept our differences, to our ability to notice the tiny things: a shell, a dragonfly (for there are so many now, and they are as big as hummingbirds!), the tiniest flicker in the water which is a fish, the flashing ripple of a tarpon’s fin, the way the sun on the water looks like ever so many diamonds.

We are part of life, we are part of nature, and yet so many have forgotten even these, the smallest things.

I think when I am able to read Gift from the Sea, so many veils will be lifted.

Until there comes a storm. And so — there is. Tonight, though they say, not a bad one.

 

Coping Strategies in an Ongoing Pandemic

personby Deborah J. Ross
schedulePosted on

From time to time, I focus on an article that in my estimation offers valuable information or reflection on the stresses of the times. These last four years have presented one crisis after another. And now a pandemic that threatens not only my life and health, but those of my loved ones and friends. So it’s a good time to review what enhances our resilience and remind ourselves that we are indeed resourceful. We are not always so, and not all of us are at the same time. Not every piece of advice will seem appropriate to each of us. One of the many benefits of community is that we can remind one another of our strength, we can role model sanity and self-care, and those of us who have hope at any given moment can carry those of us who are mired in despair through the dark hours.

We’ll get through this. Together.

On to the article: This is by Craig Polizzi, a PhD Student in Clinical Psychology, and Steven Jay Lynn, Distinguished Professor of Psychology, both at Binghamton University, State University of New York.

Your coping and resilience strategies might need to shift as the COVID-19 crisis continues

The authors highlight three strategies we might use to reduce stress and rebuild our lives, even while the pandemic is still raging. This is going to go on for a while, folks, so let’s see what we can do to make the best of this episode in our lives.

 

Cognitive reappraisal involves reframing the way one interprets an emotional or stressful event or situation to regulate or neutralize its harmful impact. You can think about working from home, for example, as an opportunity to spend more time with family, engage in hobbies or get caught up on projects, rather than as a threat to job security. This strategy tempers the kind of all-or-nothing thinking – such as “the world is unsafe,” “I cannot do anything to help” and “our leaders know nothing” – that can take people down a road of anxiety, worry and mistrust of others. Instead, reappraisal helps you move toward healthy perspectives on stressful situations, dampens negative emotions and boosts positive emotions and keenness to participate fully in life.

 

Problem-focused coping can be another helpful strategy. It frames a stressful situation as a problem to be solved and fuels planning and the search for practical solutions. For example, people who know they feel worried or depressed after consuming news can plan to monitor and control the timing (such as not before sleep), nature and amount of news they consume. Effective problem-solving increases positive emotions, self-confidence and motivation. It also lessens the psychological impact of stressors.
As society opens up, you need to weigh the pros and cons of shopping, eating in restaurants, or seeking medical treatment, informed by the best available evidence. Problem-focused coping can help you make decisions about whether an activity is safe and consistent with your personal values and the needs of others.

Lovingkindness meditation can help you get through trying times. It involves contemplating and generating positive feelings and tolerance towards yourself and others. Combining lovingkindness meditation with empathy for those with different political views, for example, can help heal frayed bonds of friendship when social support is most needed. Pausing each day to embrace love and kindness counteracts self-blame, guilt, feelings of alienation and social isolation.

And anything that increases the amount of compassion and love in the world is surely a good thing.

Protection Racket

Back when I ran a non-profit law firm in D.C., we used to get fundraising calls from an organization that represented itself as a charity supporting the police. I was surprised to learn that we had made donations to them in the past. Our office manager explained that contributing made the police more amenable to helping you and seeing you as friendly.

Now I didn’t think this was true. Such charities are usually scams or something very close to that and rarely even do much for police officers. But I know my office manager believed it was true and so did lots of other people. Those organizations preyed on that belief.

In the wake of the change in the national dialogue about the police that has come about with the protests over the murder of George Floyd, I’ve come up with an institution that’s doing something similar: police unions. They look more and more like the gang-run protection rackets of old. “You’ve got a nice little city here. Be a shame if something happened to it.” Continue reading “Protection Racket”…

Cooperation Makes It Happen

The Amish raise a barn. From Witness, 1985.

When my kids were small we watched a lot of Sesame Street. A lot. A co-worker who also had a small child and I would meet each morning to briefly determine what the Sesame Street ear worm for the day was, so that at least we weren’t cross-infecting each other with bouncy pedagologic songs. One of those sons was “Cooperation.” The lyrics were something like “Cooperation–makes it happen! Cooperation: working together.” A fine sentiment to teach four-year-olds. Or, as it more and more appears, 40-, 50- and 60-year-olds.

What is up with us as a country? With the crowd of people out there who rail against cooperating with the effort to get a handle on Covid-19 by wearing a mask, because (as I interpret it) “you’re not the boss of me?” Is this the logical endpoint of that American trope, the myth of Rugged Individualism?

Two New Approaches to Treating COVID-19

schedulePosted on

There’s a lot of very cool immunology research being done right now in response to the COVID-19 pandemic. Anti-virals and vaccines top the list for many. But there are significant problems with each — anti-virals have not proven to be wonder drugs, offering only modest help for those already seriously ill, and an effective vaccine is still months or years away. Vaccines may have to be tailored to the age and immune status of various groups, just the way flu vaccines are. But there are other ways of thinking about minimizing both mortality (deaths) and morbidity (illnesses).

Coronavirus and cancer hijack the same parts in human cells to spread – and our team identified existing cancer drugs that could fight COVID-19

This is from Nevan Krogan, Professor and Director of Quantitative Biosciences Institute & Senior Investigator at the Gladstone Institutes, University of California, San Francisco

Kinases are proteins found in every cell of our body. There are 518 human kinases, and they act as major control hubs for virtually all processes in the body. They are able to add a small marker – a process called phosphorylation – to other proteins and thus change how, if and when a phosphorylated protein can do its work. Many cancers are caused by overactive kinases leading to uncontrolled cell growth, and drugs that slow kinases down can be highly effective at treating cancer.

Kinases are also fairly easy to target with drugs because of how they add phosphorylation markers to proteins. Researchers have developed a huge number of drugs, particularly cancer drugs, that work by essentially throwing a wrench into the mechanics of specific kinases in order to stop cell growth.

Viruses also change the function of cellular machinery – albeit on purpose – but instead of causing cell growth, the machinery is repurposed to produce more viruses. Not surprisingly, viruses take control over many kinases to do this.

It is impossible to actually see which kinases are activated at any time, but since each kinase can attach phosphorylation markers to only a few specific proteins, researchers can look at the phosphorylated proteins to determine what kinases are active at any time.

Some of the more interesting ones include Casein Kinase 2, which is involved in controlling how a cell is shaped. We also identified several kinases that work together in what is called the p38/MAPK signaling pathway. This pathway responds to and controls our body’s inflammation reaction. It is possible these kinases could be involved in the cytokine storm – a dangerous immune system overreaction – that some patients with severe COVID-19 experience.

While identifying the kinases involved in SARS-CoV-2 replication, we were also able to learn a lot about how the virus changes our bodies. For example, CK2 becomes much more active during the course of coronavirus infection and causes the growth of little tubes that extend from the surface of the cell. Under a microscope, it looks as if the cell has a full head of hair. We think SARS-CoV-2 might be using these long cell outgrowths – called filopodia – as viral highways to get new viruses closer to neighboring cells, thereby making infection easier.

There are 87 existing drugs that change the kinase-controlled pathways used by the coronavirus. Most of these drugs are already approved for human use or are currently in clinical trials to treat cancer, and could be quickly repurposed to treat COVID-19 patients.*

Marine Life Thrives at Mote Aquarium in Sarasota, FL

personby Amy Sterling Casil
schedulePosted on

Everyone who knows me knows how I feel about wildlife and nature. I don’t support old-fashioned zoos that keep animals in cages, but I do support wildlife conservation efforts and study. I completely support organizations like the Mote Aquarium in Sarasota. The Mote says,

We are guardians of the sea and all living things that depend upon it

It’s a wonderful place, and they’ve put good procedures in place to ensure that visitors, staff, and resident sealife can continue safely during the COVID-19 pandemic. Visitors are allowed as long as they wear masks and follow safety procedures. Many “hands on” experiences are not possible at this time, but as Dr. Oliver Sacks pointed out to his friend Shane Fistell in one of the videos we used to watch in class, “We see with the eyes, but sometimes we see with the hands.” Right now for everyone’s safety, it’s important to keep “seeing with the eyes,” especially when we’re near living creatures who might get sick if we touch them.

Just like people, animals have personalities, and the personalities at Mote Aquarium are remarkable. One of the first animals I met while visiting there was a sprightly small turtle.

Very calm and interested, he swam for a bit, then settled back on a rock to watch the interesting, strange creatures peering into his home.

Here’s a link to the Manatee Cam so you can see what a great environment the Mote provides.

I’ve seen several manatee since we moved to Florida, but the Mote manatee, Hugh and Buffett, are “movie stars” compared to wild manatee. Their skin and tails are spotless and perfect. In the wild, manatee are covered by all manner of sea creatures and usually as well as sadly, many scars. Despite laws to protect them and lots of education, they are still injured by boating mishaps. They still suffer because of boating destruction of the sea grass they eat.

This is my best manatee picture from the aquarium – is it Hugh or Buffett – I don’t know!

I also had an interesting visit with one of the sea turtles that lives at the aquarium. They care for several sea turtles, all of which are rescues and which have different injuries or other circumstances that mean they won’t be able to safely return to the wild. Again, as everyone who knows me knows, sea turtles are among my favorite living creatures. One of the high points of my life was swimming alongside of one while snorkeling in Kauai.

So, here are two of the sea turtles at the Mote Aquarium, and the one on the right took an interest in me. Shortly after I took this picture, she took a swim around the tank, fixed me in her gaze, and swam swiftly back in my direction, at the last moment slapping the water with her right fin. Not only did she achieve a mighty splash, getting me and my phone wet, I’m certain she was laughing heartily in her turtle way at her excellent trick.

I understand that some people won’t like this picture, but I also have some friends who will love it. These are three Southern toads, who should be distinguished from the cane toad, which is an invasive species in South Florida. These three pals were just hanging out taking it easy when we walked by.

Have you ever seen such a large hermit crab? I haven’t, either, but a note – I’ve seen “adopt a hermit crab” displays in tourist areas recently and a word – just don’t. Leave them on the beach or in a facility like Mote Aquarium. Don’t try to take animals like this home and force them to live in painted shells.

This is a really nice, curious, and friendly cuttlefish. Not only does he share his ability to change his skin color and patterns instantly, he seems as curious about human onlookers as we are about him.

The Mote has a number of active, friendly pufferfish, so here’s a tip. YES, they can be poisonous. Do not touch them if you see them washed up on the beach. I’ve seen several and fortunately, what little common sense I have told me “Don’t touch it,” because they do contain toxins. Pufferfish can be blown ashore during storms and this just a sad fact of life.

So, of course they also have axolotls at the Mote Aquarium. And this delightful snapping turtle, ready to catch me with the lure inside his mouth.

As I was warned as a child, don’t play around with these snapping turtles: they can take your finger off.

I was talking to a native Floridian the other day and told her how sad it was the environment in California had deteriorated so much, even with so many environmental efforts and so much education. She said that Florida had also experienced severe environmental degradation, and that in recent years, things had been improving because people recognized the problems and made changes on their own. So, the beautiful environment that we enjoy so much today is the product of immense efforts on the part of many people. I think institutions like the Mote Aquarium are vital. The Aquarium educates everyone who goes, and they haven’t stopped with the COVID pandemic. They’ve added many virtual programs for all ages. They also have eco tours on the “Mote Boat.”

I’m poor at describing the deep emotion that washes over me when I’m in nature or around a large number of animals that are – for lack of a better word – happy. I know it’s not particularly sophisticated, but I have a measure to judge if a place like Mote Aquarium is “good” or “not so good.”

A couple of years ago when I visited the Monterey Bay Aquarium, they have an exhibit which includes hundreds of sardines swimming in a tank that encircles the viewer at eye level. The environment isn’t constructed to force the fish to confront human visitors, it’s shaped in a way that allows you to stand amid the fish in their normal behavior without disturbing them. Anyway, these hundreds of fish were doing their thing and as I stood there, I felt this overwhelming joy emanating from the hundreds and hundreds of silver, flashing, slender sardines.

I felt similar feelings from nearly all the animals at the Mote Aquarium. The Mote, and a place I’ll write about soon, Theater of the Sea in Islamorada, primarily have animals that cannot survive in the wild. They are teaching, conservation, and education institutions. They do not engage in capturing animals in the wild to force them to perform for paying customers like a sea park I won’t name. They take injured animals, rescued animals, abandoned animals, or orphaned animals and care for them. So, the animals are happy because they are cared for by people who care about them, and because they are living their lives — if not for the Mote, they would probably not survive. They also live in environments that are made as healthy as possible for them, and human visitors are constantly cautioned not to harass, bother, and certainly not harm them.

I was feeling “the feeling” of well-being at the Mote long before I met the saucy, mischievous sea turtle. When she splashed me, I knew she was living in a safe place where she could, as much as possible, be herself. There are many more special turtles that I met at Theater of the Sea — I’ll write more about them soon.

The Way of the Warrior

personby Nancy Jane Moore
schedulePosted on

I’m doing a weekly Zoom in which I discuss principles and other philosophical aspects of Aikido with several other practitioners. One of the topics we keep coming back to is warriorship.

In the news this past week, I read that a U.S. army sergeant has just been become the first woman to become a Green Beret. I cannot help but be thrilled by that. Women can, of course, succeed in programs that are designed for men, even physical ones.

But while I know that Green Berets and other special forces are intended as elite combat troops and therefore expected to have intense physical skills (ones usually associated with very strong men), our Aikido discussions make me think real warriorship has little to do with that level of physical ability.

Common Japanese words for martial arts are budo (the way of war) or bushido (the way of the warrior). But bu, usually said to mean war, can also be translated “to turn the spear,” which means it has a connotation of protection or defense. That opens up a different way of thinking.

As I began to study martial arts, I found myself drawn to the concept of being a warrior, of being the person who would stand her ground, protect others, fight for those who needed me. And, of course, to be a woman able to walk the streets or travel on her own.

That is, to be a woman who was not afraid of men. Continue reading “The Way of the Warrior”…

History is Human

Along with half the known universe, we watched the streaming version of Hamilton last weekend. I think either you love it or have no interest in seeing it at all, but I am very firmly in the former camp. We had seen it last fall with the San Francisco cast, and it was wonderful. Seeing the streaming film with the original cast was, in some ways, even better, because we kept the subtitles on, and lyrics that sped past on my first viewing landed this time, and it was, if anything, more emotionally resonant.

We followed up the next evening with 1776, our annual 4th of July tradition. (The first time I saw it–I must have been in college–I developed a serious crush on Thomas Jefferson: tall, red-haired, wordsmith, plays the violin, looks suspiciously like Ken Howard –no, actually, he didn’t, but never mind that. Subsequent learning took a lot of the gloss off Mr. Jefferson.) I love this show because it captures something important about the origins of my country–it glances off the flaws of the men, but doesn’t skip over the compromises: Here’s John Adams protesting against the removal of a clause condemning slavery:

John Adams: Mark me, Franklin… if we give in on this issue, posterity will never forgive us.

Dr. Benjamin Franklin: That’s probably true, but we won’t hear a thing, we’ll be long gone. Besides, what would posterity think we were? Demi-gods? We’re men, no more no less, trying to get a nation started against greater odds than a more generous God would have allowed.

They’re both right. Posterity–rightly–has not forgiven them. And maybe, likely, without the compromise over the mention of slavery, the south would have walked and the war would have gone the other way.  Continue reading “History is Human”…

Disappearing Stars and Other Cool Science Stuff

A ‘monster’ star 2 million times brighter than the sun disappears without a trace

In 2019, scientists witnessed a massive star 2.5 million times brighter than the sun disappear without a trace. Now, in a new paper published today (June 30) in the journal Monthly Notices of the Royal Astronomical Society, a team of space detectives (see: astrophysicists) attempt to solve the case of the disappearing star by providing several possible explanations. Of these, one twist ending stands out: Perhaps, the researchers wrote, the massive star died and collapsed into a black hole without undergoing a supernova explosion first — a truly “unprecedented” act of stellar suicide.

Treading Lightly: Growing Greens

personby Pati Nagle

Here in the Treehouse, we have to get by on what’s at hand. This series explores simple, nature-friendly alternatives to conventional products and practices.

When you’re in a treehouse, in the middle of the woods, there is no popping down to the corner store for last-minute whatevers. Our excursions are few and far between, so we are coming up with ways to compensate for the lack of easy access. We find this has also led us to try some more eco-friendly methods – in this case, for acquiring greens.

Gardening at the base of the tree is not an option. Never mind the climbing up and down; anything we might try to grow on the forest floor would be quickly snarfed by the local fauna. But I want lettuce. Fresh green things to eat. Greens that I know are uncontaminated.

Hydroponic tower garden

So I started growing lettuce in my office. This tower rack sits in the corner, taking up a 2’x3′ footprint. It’s got lettuces up top, seedlings in the center, and bok choy and basil plants on the bottom. All of these (well, not the seedlings yet) produce amazing amounts of wonderful leaves.

Fresh veggies, especially greens, start to lose nutritional value the moment they’re picked. In 24 hours, they’ve lost 90% of their nutrition. By growing them here, I have clean, absolutely fresh greens year-round, with a carbon footprint of…well, probably zero. The lights are LEDs and are powered by our solar system. Each lettuce plant uses around two gallons of water during its lifetime, compared to more than twenty-five gallons it takes to grow a head of lettuce in the ground.

The low carbon footprint is important to me, almost as important as the clean food. That Romaine heart that I used to buy for a couple of bucks had to travel from California, and was probably over a week old, maybe a couple of weeks old, by the time I brought it home. And while a couple of bucks seems fairly inexpensive, it’s a lot more than the cost of my lovely home-grown lettuces.

Growing these darlings is a bit different. You don’t wait for the lettuce to get big and then yank it from the garden. Instead, as soon as it’s big enough, you start harvesting the outer leaves, a few at a time. (I have been known to snack on a leaf now and then.) The plants get harvested this way for two or three months. When they’re tired, they bolt, and I retire them with thanks and a bit of ceremony. Each plant has probably given as much lettuce as two or three commercial lettuce heads, by then.

It’s a different way of gardening, and a different way of interacting with food. I’m very aware of the interdependence between me and my plants. I feed them and make sure they have enough light and don’t get too hot, and in return they feed us. Mutual giving.
