The Comfort of Crows by Margaret Renkl

 


 “What more could anyone ask from a new year than the promise –or just the hope—of renewal?” Margaret Renkl.

  I dare say that hope is not enough. Hope is in desperate need of awareness, reflection and inspiration to make sustainable, empathic choices.

  I was drawn into Margaret Renkl’s world when I learned about her interest in rescueing a sick fox. Margaret Renkl lives in Nashville, Tennessee, where she has formed a close bond with the wildlife on her backyard by observing her surroundings.

  The sick fox was probably suffering from mange. Margaret explains that mange is common in suburban foxes because the “manicured” gardens deprive foxes of the sources of food they need to survive. Under normal, healthy conditions foxes’ immune systems may be able to fight off the mites that cause mange, but suburban foxes suffer the consequences of the use of poisons that people use in their gardens. “Manicured” lawns use different poisons, and Margaret Renkl elucidates it in simple terms:

 “Homeowners set out poisons that keep seeds of weeds from germinating. Then they spray a different poison that kills any plants that germinate anyway. Still another poison kills the insects that eat the “desirable” plants. Yet another kills the field mice trying to survive in a place without fields.

“And those poisons end up in the air and the water. They end up in our bodies, linked to asthma, Alzheimer’s disease, Parkinson’s disease, autism, and several cancers.” She is distraught to watch the consequences of bluebirds ingesting poisoned insects, and Cooper’s hawks eating those bluebirds.

  I am thankful for this book, for it conveys the information that can make a difference in our communities.

  Over the years I've tried to communicate her message in several ways to different people, but to no avail. I witnessed a massive increase in the use of pesticides and herbicides recently.

  I used to relish the visit of various kinds of bees on the wildflowers in my pollinator garden, and I wrote about bees a few times here. Then in the year 2024 I hardly saw any bees in my garden. It was a lonely experience.

  I contacted a professor of entomology from a reputable university. I was sent multiple scientific papers, which validate my concerns and support the content of My Writing life blog. I have used several books at My Writing Life blog: Awareness, reflection, Inspiration to motivate people to do the right thing, but it has not been enough.

   I still come across the fake “pollinator gardens” with pesticides on the lawn. It is necessary to communicate the message with clarity: a pollinator garden with pesticides on its lawn is NOT a pollinator garden. Pesticides take a toll on the health of pollinators, so let people know that by using pesticides on their lawn they are not creating a pollinator garden. They are doing just the opposite.


  What is not to like about the graceful flight of a monarch butterfly visiting our backyards?

 





  I am thrilled when I come across a toad in the safe haven of our garden. We don’t spray herbicides and pesticides in our yard. In refraining from spraying poisons, we create a little forest of hope in our tiny corner of Mother Earth.

 I could spend hours appreciating the masterpiece of patterns and colors that Mother Nature put together in this toad’s skin…I had never seen a toad like this one before, so I took this photo. Strangely enough, this toad has the smooth skin of a frog. I am enchanted by the beauty and mystery of this amphibian.  



  Did you know that toads can feed on thousands of mosquitoes every summer? Yes, they do eat a variety of insects, and mosquitoes are included in their menu. We don’t have to poison the toads. They are very sensitive to the chemicals humans use in their gardens. We need the toads to do what they are expected to do in maintaining the integrity of the ecosystems where we can all thrive without poisoning our water, air and soil.  



  With climate change getting worse, no repellent will be able to deal with the consequences of the proliferation of mosquitoes. Diseases such as Dengue and West Nile encephalitis, which are transmitted by mosquitoes, are rising steadily.

  Mosquitoes are part of the source of food for toads and spiders, and we need toads and spiders in the web of life, but the use of pesticides and herbicides are destroying their lives, and, in the process, we are suffering the consequences of this lack of judgment. The bats are also in need of protection, and I explained this before here.

  The gist of The Comfort of Crows

 The Comfort of Crows is akin to a personal journal in which Margaret Renkl shares her connection with wildlife and her concerns over what we humans are doing to the environment and to ourselves. There are threads of her personal life interwoven into her narrative, but the charm of her book lies in her observations of wildlife and her response to her setting. In other words, she shares her poetical musings and the practical ways in which she tries to support what remains amid the destruction caused by irrationality, denial and neglect.

  The limitations of her actions did not stop Margaret Renkl from making choices that leave sparks of hope for the reader.  



   She contemplates the wonders of the four seasons, marveling at the lives of the creatures that surround her. She also shares the grief that emerges from watching nature closely. The effects of climate change and the multiple poisons that people use in their “manicured” gardens are evident.

   I think we should start calling them gardens of death or doom instead of using the word “manicured” gardens to refer to the abuse of such chemicals.

    It was also heartbreaking to read about the loss of some of the trees in her own garden, which took place after the happily married couple next to her backyard died. The builders came with their equipment and harmed the roots of her own old trees.

  As you know, the roots of trees do not understand anything about property lines, so the parts of the roots that were harmed in her neighbors’ home killed her trees altogether.

  The thoughtless actions of these builders could be used as a metaphor and a symbol of the lack of awareness and empathy in certain human behaviors.

 

Trees are not just trees

   Trees provide the oxygen we need to survive. They provide relief from the intense summer heat and protect the soil from erosion. Trees are not just trees, but they are also the organisms that live in them. Furthermore, trees supply the dead leaves that feed the soil, the leaves that form the shelter on the ground to various living beings belonging to complex ecosystems that support our own life on earth, and all these creatures play necessary roles in the precious web of life. You may not see them, but they are there and they need those dead leaves on the ground.  

 

 


  Using mathematics to spark awareness

   You will encounter people who don’t understand that destroying the environment is bad for the economy. I come across them often. We are responsible for helping them understand that supporting the health of ecosystems makes our economies stronger, and we have to make clear that destroying ecosystems is shattering economies across the world. To do so, we can use the power of mathematics. I can give a few examples here:

   A single bat can eat 3,000 insects in one night. Bats contribute one million dollars a year to Thailand’s economy by helping to reduce the loss of rice crops. In the United States of America, bats save three billion dollars every year by protecting corn and cotton crops. In addition to being pollinators, bats’ droppings are effective fertilizers. Poisoning their sources of food is a very bad idea.

  More than 80 percent of the leading 115 major crop species worldwide depend on or partially benefit from floral visitation by animal pollinators. Pollination by animals contribute to an estimated 35 percent of global total crop production. Globally, the animal value of insect pollination of plants was estimated to be around 190.5 billion U.S. dollars.

  In addition to addressing the massive use of pesticides and herbicides, we have to acknowledge and tackle the climate crisis. Climate change will continue to increase the price of food. In 2023 extreme weather events such as heat waves, droughts and floods were the main disruptors of food prices, even though the mainstream media has failed to report this critical issue consistently. These events caused widespread damage to crops and livestock globally.

 Rice, for example, cannot get efficiently self-pollinated in hotter temperatures. Extreme heat degrades the grain quality and reduces its yield.

 Severe weather patterns degrade the quality of our produce. Heat waves scorch fruits and vegetables. Furthermore, an excess of carbon dioxide in the atmosphere affects the micronutrient content of produce.  The elevated levels of carbon dioxide led to a decrease in the root uptake of nutrients by the plants according to research. A decline in the content of minerals in the plants, such as zinc, potassium, nitrogen, calcium, magnesium, phosphorus, iron and copper due to high levels of carbon dioxide in the atmosphere has been well documented.

 Severe weather events are expensive reasons for crop loss: for example, 118.7 billion dollars in 2021-2022 were lost in crops value.

  In the year 2024, 500 billion dollars were lost in damages in the United States of America due to extreme weather events according to a report by AccuWeather. To understand how disaster events are on the rise, it may be helpful to check the graph from this link of Yale Connections:

 The artworks in this post and my final message

   I have shared some of the delightful artworks included in the book. The artist who created the masterpieces is Billy Renkl, Margaret’s brother.

   I will close this post with a quote by Margaret Renkl, because it summarizes what she tries to communicate in The Comfort of Crows:

     “I rejoice in what is eternal, even as I force myself to face what is not, to let my heart be broken again and again and again. The very least I owe my wild neighbors is a willingness to witness their struggle, to compensate for their losses in every way I can, and to speak on their behalf about all the ways I can’t.”

Beyond the War on Invasive Species: a Permaculture Approach to Environmental Restoration by Tao Orion

 


 

“It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.”-Charles Darwin

Thousands of animal and plant species are in the process of migrating to adapt to the conditions that climate change imposes on them for their survival. Considering this fact, how can we expect ecosystems to be “unchanged”? We can’t. Ecosystems are dynamic. The concept of “invasive” species becomes a controversial one when one cares to analyze the intricate ways in which everything is connected.

  New species have to adapt to their new surroundings. You are not alone if you have been wondering about the implications of the new situations that arise as a result of climate change and other phenomena. I have noticed how this subject has been conveniently neglected, so I am thankful for Tao Orion’s book.

    Tao Orion explains that non-native species are the symptoms of a complex situation caused by human actions such as logging, mining, emissions of greenhouse gases, unsustainable agriculture, pollution, war conflicts and other human destructive behaviors. The root causes of the presence of invasive species are not even taken into consideration when resorting to the use of herbicides and pesticides with the futile goal of eradicating a species under the delusion that these chemicals will not affect the native ones. (These chemicals may increase the revenue of the manufacturers, but there is no evidence that they support biodiversity, human health and the environment).

 When Tao Orion was employed to restore land in 2010, she was shocked to learn that she was expected to use Round Up for her work. As an organic producer of food, she disagreed with this management. Today we know more about the effects of herbicides and pesticides, and we are continuously learning about the consequences of climate change, so Tao Orion’s book has become more relevant.

  Research on the effects of Glyphosate, for example, continues to emerge. In 2023 research conducted by scientists at UC Berkeley School of Public Health showed that “childhood exposure to the world’s most widely used weedkiller, glyphosate, is linked to liver inflammation and metabolic disorder in early childhood, which could lead to liver cancer, diabetes, and cardiovascular disease later in life.” You can read about it here, and learn more about the researchers’ recommendations.

 

  While it is necessary and important to foster the growth of native plants, it is also crucial to understand the issues that bring in new species to a place in order to address the root causes of the shift instead of adamantly trying to eradicate a so-called “invasive” species. It is also crucial to understand how new species interact with the environment, because this may help to advocate for strategies that can integrate non-native species into the new environment. For example, pollinators may benefit from flowers that are not considered to be native.

  Even though Tao Orion’s book was published in 2015 and some specific points may be outdated, her approach introduces the science of permaculture to restore ecosystems, and encourages us to apply this knowledge to our daily choices in our own gardens. The book contains a foreword by David Holmgren.

  Tao Orion advocates for methods that consider the relationships in ecosystems, not only those among the living beings in specific habitats but also their interactions with water, air and soil.

 Classifying species into “native” and “invasive” groups is akin to labeling them as the “good” versus the “bad” ones.

“We could define nativism as the war against naturalizing species, an ideology that sought to separate nature into good and bad species according to some fixed historical reference.” A paradigm shift is necessary. Ecologist Haikai Tane in New Zealand coined the term “ecosynthesis” to describe the restoration of ecosystem function in the process of combining native and foreign species that colonized abandoned landscapes.

 

I invite you to read this interview with Tao Orion to learn more:

 As I type these words, my gaze wanders out the window to embrace the vibrancy of the fall leaves swirling and settling on the ground, creating a composite of hues: ochre, yellow, red and orange. Leaves are an excellent source of nutrition for the soil. Putting them in plastic bags to send them to the landfill is a very poor decision. Leaves are rich in minerals that can support the soil and the development of new plants. People waste money buying mulch when they could simply use the leaves as mulch. The leaves can also be shredded before using them for compost. This link provides some ideas.

 The leaves on the ground also form habitats, establishing new sources of shelter and food for various creatures. There are many worlds of life around us that we often take for granted…

What A Bee Knows: Exploring the Thoughts, Memories and Personalities of Bees by Stephen Buchmann

 


  Bees remember and recognize human faces. I wrote about this on a post last year, and I mentioned some facts about the fascinating brain of a bee.

 The brain of a bee is about the size of a poppy seed, but it contains almost one million neurons.  I was thrilled to discover Stephen Buchmann’s book, which was published by Island Press this year, so I borrowed it from the library as soon as I learned about it.

 Buchmann is a pollination ecologist who specializes in researching bees. His book takes us on an adventure to explore their sensations, minds and experiences. His goal is to spark wonder and curiosity for bees, and to dispel fears. 

 Buchmann describes the structure of a bee brain and the ways it functions. I was astonished to learn that brain chemicals (neurotransmitters) that exist in our own brains and influence our behaviors also exist in bees. For example, serotonin and dopamine are also found in bees. 

 What a Bee Knows reveals details about the intriguing lives of different species of bees. We learn about their behaviors, moods, nutrition and special abilities. Most bees feed on pollen and nectar.

 You may have heard about the “bugs” living in our gut, and how these bugs make up the composition of our microbiome. Our microbiome is linked to our health and general wellbeing. You will be surprised to learn that bees also have a gut microbiome. Researchers are actively studying their microbiome and how this amazing assemblage of bacteria, fungi and viruses is connected to their health. For example, Buchmann and his colleagues have found Lactobacillus in the gut of honey bees.

 Some of the components of the bees’ microbiome transfer from the pollen of flowers when the bees visit the flowers, and some of the protein from the microbes in the pollen are part of the nutrition of the larvae of the bees.

 Pesticides and herbicides in the environment cause a disruption of the microbiome of bees, and this has the potential to compromise their health. Currently, bees are in serious decline and there are many reasons for this.

  Climate change is an important one. The massive amounts of carbon dioxide spewed by burning fossil fuels continues to worsen climate change. Everybody is impacted by climate change. Bees are not an exception. Pesticides are fossil fuel- based, so they belong to the same issue that deserves our attention and understanding.

 Let’s share some figures from Buchmann's book to emphasize the need to protect bees:

"About 80 percent of the world’s 369,000 species of flowering plants depend upon insect pollination for fruit and seed set. More than 80 percent of the leading 115 major crop species worldwide depend on or at least partially benefit from floral visitation by animal pollinators. Pollination by animals, with bees predominating, contributes to an estimated 35 percent of global total crop production. Globally, the annual value of insect pollination of crop plants is estimated to be around 253 billion US dollars".

 Bee pollination improves both the quality and quantity of the crops. Food, fiber and beverage production depend on bees. Bees even ameliorate shelf life and commercial values. "We need bees more than they need us". 

  It is time to push human arrogance aside and do what it takes to support them. The good news is that we can help bees to survive and thrive by making mindful choices:

 


Plant wildflowers. If you don’t have a yard, use your window sill. Everything helps. Avoid buying hybrid flowers because those plants are selected to please humans, not pollinators, so they may have little nectar or pollen. Choose plants that are adapted to the local soil and climatic conditions. Native plants will entice a vast array of pollinators and will enliven your garden in delightful ways.

 Avoid using insecticides. Neonicotinoids, for example, are responsible for decimating bees and other pollinators and they still continue to be on sale.


 You can learn more about this here:

 https://wisconsinpollinators.com/Articles/Neonicotinoids.aspx

Roundup contains glyphosate, which affects the gut microbiota of honey bees. Other ingredients in Roundup are also toxic.

Avoid using lawn chemicals. Lawn care products contain hidden insecticides and herbicides. Besides, you risk harming yourself, your family and your pets. Enjoy the dandelions and clover. Remember that clover enriches the soil.

Avoid herbicides; they lower the number of blooms. Roadside weed blooms are food sources for various pollinators. Even though fungicides used on fruit trees don’t kill bees directly, they contaminate the food used for the bee larvae. This contamination affects the gut microbiome, whose integrity they need to stay healthy. 

Avoid mulching flower beds or paths. Thick-chipped bark mulches in flower beds harms bees. Around four thousand species of native bees in the United States are ground nesting. They need bare ground to make their nests.

Dead trees or limbs provide a habitat for leafcutter bees, mason bees, and other wildlife. Don’t remove them. 



There are projects you can join to support bees as a citizen scientist. You can also visit sites that post relevant information about bees:

https://www.beesinyourbackyard.com



  It goes without saying that everything we can do to address climate change is crucial  to protect bees as well. 

 Understanding the complexity of their brains and behaviors is an important aspect of the book. However, when the author compared the bee brain to the human brain he stated that human beings are born with a fixed number of neurons, and that this number does not change after birth. This has been debunked by research. Neurogenesis has also been documented in human brains, and it is also relevant to emphasize the concept of neuroplasticity. 

 Neuroplasticity is the process through which new connections and pathways develop in the brain, and brain stimulation plays an important role in boosting neuroplasticity. Doing activities that stimulate the brain, such as reading, learning new skills and other activities can help to foster neuroplasticity. The good news is that keeping a healthy lifestyle with adequate nutrition, sleep hygiene, exercise and meditation helps to support the neuroplasticity of the brain. The bottom line is that neuroplasticity happens in bees as well as in human beings.

  I found this amazing interview to Dr. Julia Basso. She is a neuroscientist, yoga instructor and dancer who researches the effects of yoga and dance on the brain. Last but not least, if you want to keep your brain healthy, avoid smoking, alcohol and drugs as part of your supportive plan.

 I never understood the fear of bees. I work alongside them without any kind of problem. If we treat bees with respect and consideration, they have no reason to attack us, so it is time to make choices that support their survival. We can all do our part to protect them. In doing so, we are supporting our own wellbeing as well as the present and future of all life in this beautiful planet.
