Book Review: Silent Spring

27333Who among us can say they wrote a book that changed the world? Certainly that title belongs to very few. Despite my own environmentalist philosophy, it’s taken me a while to get to reading Rachel Carson’s seminal work: Silent Spring. This was a book that truly launched into preeminence the environmental movement. Loose threads of concern and activism were tied together by a common core and for a common purpose. Unfortunately, Carson died less than two years after publishing her work, and so she did not see the true force of impact it had on the world—but we see.

Silent Spring, despite its age (published first in 1962, and I read the 50th-anniversary edition with a new Introduction and Afterword), is still monumental, and even revolutionary. Carson starts with a question: “What has already silenced the voices of spring in countless towns in America?” and gives this first, preliminary answer: “This book is an attempt to explain.” However, she does much more than just that. The book is a comprehensive look at what was once perhaps the gravest environmental problem facing the United States: the overuse of dangerous pesticides. Though she doesn’t spell it out in so many words, Carson explains the problem, its nature, its many faces and guises, and, remarkably, spends a great deal of time on potential solutions as well. This is something I haven’t seen much in environmental books: generally, there is a great deal of meditation on problems and very small-scale, specific solutions. Carson, however, goes to great lengths to prescribe alternative methods of controlling pests that aren’t as harmful as pesticides. I’ll get to that in more detail in a moment.

The structure of Silent Spring is impeccable. There is, first, a call to action: the hypothetical small town in America, witness to mysterious death and affliction and crisis of health. Carson then spends time going into the workings of various pesticides. There were two primary categories of pesticides in use at the time: the chlorinated hydrocarbons (including the infamous DDT) and the slightly newer organic phosphates. Each group has differing biochemical effects, which Carson takes the time to describe before then explaining how these pesticides can infiltrate groundwater, soil, and vegetation. I found myself grateful for my background in ecology during these early chapters: otherwise, I would’ve had a large amount of material to digest and process before moving on. This technical emphasis could be a deterrent to readers not as versed in scientific processes (like bioaccumulation and nutrient flow), but Carson is adept at explaining advanced concepts so that even a layperson could understand.

She continues by delving right into the heart of negative impacts on the environment: deaths and population reductions in plants, wildlife, and culminating in human effects. Two chapters at the end are devoted to how health impacts can come about in humans, specifically with the fact that some pesticides can damage cellular metabolism or replication (causing mutations and defects in chromosomes).

Silent Spring concludes powerfully: at first by demonstrating that in many cases, attempts to eradicate pests using insecticides completely fails, and then by offering a plethora of counter solutions.

The tone of the book was fascinating: a unique juxtaposition of dark and light. On the one hand, the problem addressed by Carson is a true war on life itself. She has too many examples of death and malady to effectively process—an overwhelming array of streams without fish, roadsides barren of wildflowers, children sickening and dying after accidental contact with pesticides, flocks of birds convulsing and dead upon the ground, trees wilting—it is horrifying to think that at one point this was the norm. At one point in our history, this death was accepted as necessary. One chapter, in particular, presents a scenario of “ordinary life” that, to me, seemed like some kind of horrific dystopian science fiction novel: pesticides contaminating literally every food item (one example was brought up of an Inuit who only tested positive for DDT in his body fat after a stay at a hospital where he consumed the processed food), homeowners treating their lawns and shrubs with potentially deadly chemicals, and pesticides like dieldrin and chlordane in common use to kill insects in the home. This chapter was incredibly striking after learning of the many ravaging effects of chlordane, dieldrin, and others.

Amidst all of this death, though, is the prospect of hope. Carson takes time in most chapters, and then again in one entire chapter at the very end, to list examples of alternative solutions to pest control. She describes weaker, safer pesticides, but spends most of her text space describing biological solutions. These include the introduction of predators and parasites of invasive pest insects, management of plant ecosystems to control plant pests, the spreading of highly-specific insect pathogens, and even the release of sterile male insects (like the screw-worm) to control populations. This focus on biological solutions is related to perhaps the most revolutionary (at the time) aspect of Silent Spring.

Carson continuously uses whole-systems perspectives to explain the impacts of pesticides. She rarely focuses on one species or problem but links everything together. “In nature nothing exists alone.” Ecology was then a young science, and so the fixation that Carson has on explaining ecological processes and connections impressed me. Her holistic language cultivates a sense of connectivity and reciprocity.  Humans are not separate from our world or from nature. Her prescription of solutions keeps this ecological perspective in mind. “Sometimes we have no choice but to disturb these relationships,” she writes, speaking of ecological ones between different lifeforms, “but we should do so thoughtfully, with full awareness that what we do may have consequences remote in time and place.” However, “where man has been intelligent enough to observe and to emulate Nature he, too, is often rewarded with success.”

Indeed, many of the examples of biological controls she describes at the end are successes. Perhaps this involves a bit of cherry-picking (presenting the most harmful examples of chemical pest control and the most successful ones of biological pest control), but the downsides are obviously much preferable to an overt poisoning of life.

My only qualms with the book were not exactly with the book itself or its author, but with the fact that some of the information was, of course, outdated. For example, Carson spends a chapter explaining how cancer may arise in humans due to pesticides, but some of the ideas and hypotheses are basic and have much new information (we know a great deal more about cancer development now than in the 1960s). So, I will be on the lookout for books in the vein of Silent Spring that contain updates to the information or situations presented therein.

I would recommend this book to everyone. Carson manages to explain difficult concepts so that everyone may understand them, so the science should not be a barrier. Although this is a (mostly) past issue, it has many chilling echoes even to today. Pesticides are still in use, and should still require great study and care in administration. A few examples were made of insects developing resistance to certain insecticides, an issue which is the precursor in spirit to one of our most pressing modern problems: that of bacterial resistance to antibiotics. Perhaps, like the researchers studying biological controls for insects, we must find clever, unprecedented methods of dealing with bacteria and pathogens. In particular, Carson notes that resistance usually develops faster in warmer climates where insects have faster generational overturn. This could perhaps become an issue again with the onset of climate change. Warmer temperatures could mean more insect generations per year, which could mean the development of resistance to modern insecticides and a higher rate of insect-borne disease spread.

Of course, biological controls are not without problem, themselves. We do know better now how to be careful when introducing predators and parasites of invasive species, but several chains of destruction have been instigated by the introduction of yet another invasive species into a new habitat (the species, which was supposed to only control the first invasive species, instead causes devastation to some native species). Therefore, in no way should Silent Spring be taken literally anymore. Its information—both problems and solutions—are past and in need of updating. Its ideas, however, are still relevant, and as long as the reader places it in proper historical context it is still worthy of reading.

I would love to see the template of Silent Spring used by more environmental books today. A focus on both problems and solutions, despair and hope, gives the reader more to focus on than just a sense of doom. I get that feeling from a lot of environmental literature today; this is understandable, given the grave threats that life on Earth currently faces, but I believe a work may become more impactful if it attains the tone and structure present in Rachel Carson’s book.

As I read the 50th Anniversary edition, I will also take a moment to state that both the Introduction by Linda Lear, which goes a bit into the biographical details of Rachel Carson, and the Afterword by E. O. Wilson, which delves into the book’s impacts and Wilson’s own experience of them, were worthy additions to Silent Spring. Having a bit more context in which to place this work was extremely helpful.

To conclude my thoughts on Silent Spring (which are many and ongoing), I do recommend this book for anyone who wants a sense of what the world has faced and continues to face. Perhaps it would give everyone the perspective needed to understand that humans have the power to change the world for the worse. Specifically, it gave me a huge appreciation for modern industry regulations. Although demonized by certain groups, regulations serve a basic purpose of keeping us safe. Without them, we would still be using deadly chemicals like those described in Silent Spring. And without Rachel Carson’s book, perhaps we would have made the connections too late to save ourselves and our world from markedly greater destruction.


To the reader: If you’ve read Silent Spring, I’d love to hear your thoughts. I’d especially love to hear what you think we can take away from it today, with our modern environmental problems.
