David Waltner-Toews

Continuing my reading of anything and everything related to pandemics, I couldn’t help but jump at one with pandemic in the title. This is an updated edition of David Waltner-Toews’ The Chickens Fight Back, published in 2007. There are references to COVID-19 in this book but primarily this is a book about various diseases which can be transmitted to humans via animals. Waltner-Toews is an epidemiologist and veterinarian and it’s clear that his passion is in diseases that cross the animal kingdom.

If you’re looking for a book that talks about the people and the steps taken during a pandemic, this isn’t it. The book is firmly rooted in the biology and transmission of zoonoses. Waltner-Toews clearly has a lot of knowledge and experience in this field, much of it pertaining to animals (which makes sense because they are the ones transmitting these diseases to humans). For me, I’m not as interested in the animal vectors except that they exist. There is also a reasonable amount of microbiology in this book, which is rather dry at times. The author has a considerable amount of wit and certainly isn’t afraid to put his ideas, including politics and religion forward. More humour may have improved this book for me, particularly after a day of living the pandemic reality. At times, it was too dry to hold my interest. At others, it was fascinating. The problem for me was that I didn’t know what I was going to get each night, which led to me not picking up the book and watching Netflix…

I think if you’re looking for a general education on zoonoses this would be of interest. But although these micro-organisms can and have caused epidemics and pandemics, this book is not focused on the human response. I feel the title is misleading to the lay reader and the original title would have sufficed for the second edition.

This is a look at how eating one of the 1,900 edible insect species in the world may reduce hunger and starvation. The book looks at how insects evolved, their impact on humans, human impact on insects, and their role in culinary delights. He included examples where insects consumed for survival turned into valuable cash crops. If not food for the stomach, the theories presented are certainly food for thought. The author used over five hundred scholarly and popular books, papers, and websites to research insect for the book. The author included a selected biography, endnotes, and index.

I received this book through a random giveaway. Although encouraged as a courtesy to provide feedback, I was under no obligation to write a review. The opinions I have expressed are my own.… (altro)

Warning: This review will contain the word shit as it fully encompasses the subject of the text. If that offends, feel free to skip this one; if not, read on.

David Waltner-Toews, in The Origin of Feces, dives face-first into the subject of excrement. While at heart an epidemiologist, he found that a fair number of epidemics are caused by parasites, bacteria, or toxins from feces entering the water table and infecting humans. Shit, in all it forms, is infectious, but causes massive ecological change in many positive ways. Birds process seeds and deposit them far afield so that plants can move across the landscape. Plants process energy and essentially “poop” out oxygen for us to breathe. Even the lowly dung beetle, while rolling about balls of shit all day, helps to recycle larger piles of scat into the soil for re-nitrogenation.

The trick with looking at shit on an ecological scale is to understand that it both harmful and helpful. In some ways, the large-scale breeding of livestock is leading to a global increase in excrement, and the world is having trouble processing all of it. While many good can come from animal waste (think musk and ambergris), many of the methods we use to deal with it cause imbalance in the larger ecosystem of the planet. Toews investigates some of the local methods for dealing with waste issues and how they have either succeeded or failed. This book would make a great companion piece for either Steven Johnson’s The Ghost Map or W. Hodding Carter’s Flushed. All in all, it will make you give a shit—and that just the author’s hoping for.… (altro)

The end is near

How could you not buy a book called The Origin of Feces? Darwin would have plunked for it in a heartbeat. When you flip through it you see chapter titles like Turds of Endearment, The Other Dark Matter, and Know S__t.

Sold.

What you get is a spider web. The more you read, the more you are drawn into an ecological analysis like you have probably never seen. There are lots of puns, lots of jokes and lots of anecdotes – at first. But it gets serious and comes out hopeful in, as it were, the end.

Although there is lots of interesting information on evolution and the role of waste, the real impact comes from the unfathomable complexity of ecology. We know next to nothing. Everything we do on this planet has an effect, and it’s usually negative. We learn that the remaining sperm whales remove 200,000 tons of carbon from the atmosphere every year. So what will it be: sushi or clean air? It also turns out that ambergris, that precious, rare fragrance additive, is composed of whale waste. Musk is civet waste. Guano in Peru is protected by armed guards. Some Amazonian fish feed on fruit, and spread the seeds as waste. If we decide to “harvest” the fish, it will cripple fruit tree numbers there. Everything plays a role; every activity has an outcome. But we are not adding value.

For a very long time, we used to appreciate the role of human waste. In 18th century Japan, they were already practicing sustainable agriculture. Tokyo, (then called Edo) crossed the million mark in 1721, and managing the waste with zero technology was not a problem. Homeowners and building owners sold it to farmers, who sold the resulting vegetables in markets there. If there was a vacant apartment, everyone’s rent went up because there would be less waste for the landlord to sell. In those days, 50% of waste went to fertilize the fields. Today, not so much. Toews says we are “mostly amnesic about the ecological and economic benefits of manure.” We prefer chemical compounds we know nothing about. We turned feces from a solution into a problem.

The increase in population and the increase in farm animals mean waste is out of control in addition to not being employed. Disease outbreaks occur all over the world, with increasing frequency, scale and effect. Technology has not kept pace.

The main point seems to be that if we think we have THE solution, we are way off base. Everything we do to produce more is killing off life that uses it. Pesticides that make for higher yields also kill off dung beetles that bury manure in the earth. Recycling and importing are a near total disaster. We import water and nutrients (translocation) in foods from all over the world, depriving the originating country of them, and polluting the receiving country with foreign nutrients and bacteria in waste. Even within the nation, we take nutrients from the countryside where they are needed and expel them in cities where they are a problem. We are physically altering global ecosystems. We have no idea what that means.

Our big scale solutions pose possibly the most danger. They can do the most damage and if they go off course, their negative impact could be disastrous: “In the long run, health for all means grief for many.” That’s a Catch-22 we need to consider. And if we look to same source to solve the problems it created, we’re certain to screw up – and that according to Albert Einstein.

Technology is not going to be the solution. So Toews looks to tackle problems one by one. He cites all kinds of innovative projects all over the world. Some are specific to their location and climate. Some succeed admirably. Some don’t do much. But this way, we can’t push the planet over into Tilt while we deal with the mess we created.

Toews himself is still out there changing the world. He founded Veterinarians Without Borders, and has written widely and deeply. His passion is front and center. His humor is a welcome addition to a serious problem, making The Origin of Feces a worthy read.

Not a s____y book at all.… (altro)
