Microbial ecologists once had the luxury of no one caring about their work. My colleagues and I had been busy showing that there are more microbes than stars in the Universe, that the genetic diversity of bacteria and viruses is mind-boggling, and that microbes run nearly all reactions in the carbon cycle and other cycles that underpin life on the planet. Then came the heat waves, wildfires, droughts and floods, and other unignorable signs of climate change. Now everyone should care about microbes to appreciate the whole story of greenhouse gases and to understand how the future of the biosphere depends on the response of the smallest organisms.
How can you not love a book that argues that, despite being mostly microbial, “the plankton form the bulk of the living fabric of the ocean, the web of life that is an integral part of the blue machine.”
Czerski’s prose is as vivid as describing other, larger parts of the blue machine, such as Greenland sharks, which live for hundreds of years, and whales whose earwax records the stress caused by global warming. Equally entertaining and captivating are her accounts of canoeing off Maui, fieldwork in the Arctic, and everyday life on an oceanographic ship.
Although the writing is always light and the metaphors evocative, Czerski makes several serious points about the ocean and climate change. If not for the ocean, atmospheric levels of the most important greenhouse gas, carbon dioxide, would be even higher and global warming worse.
All of Earth's oceans, from the equator to the poles, are a single engine powered by sunlight, driving huge flows of energy, water, life, and raw materials. In The Blue Machine, physicist and oceanographer Helen Czerski illustrates the mechanisms behind this defining feature of our planet, voyaging from the depths of the ocean floor to tropical coral reefs, estuaries that feed into shallow coastal seas, and Arctic ice floes.
Through stories of history, culture, and animals, she explains how water temperature, salinity, gravity, and the movement of Earth's tectonic plates all interact in a complex dance, supporting life at the…
As a microbial ecologist, I didn’t need to be convinced that microbes make all life on Earth possible. I knew that Falkowski, a preeminent biological oceanographer, would be a trustworthy guide in the microbial world. What makes this book so much fun to read is how Falkowski mixes science with snippets of history, both his own and of early scientists.
Yet, the science is the main story here and is fascinating. Microbes, specifically cyanobacteria, are the engines that first put oxygen in the atmosphere around 2.4 billion years ago, which set the stage for the evolution of more complicated lifeforms, including, eventually, Homo sapiens. Microbes are also the ancestral source of what Falkowski calls nanomachines, which continue to power all organisms today. Falkowski convincingly argues that microbes are what make life on Earth possible.
For almost four billion years, microbes had the primordial oceans all to themselves. The stewards of Earth, these organisms transformed the chemistry of our planet to make it habitable for plants, animals, and us. Life's Engines takes readers deep into the microscopic world to explore how these marvelous creatures made life on Earth possible--and how human life today would cease to exist without them. Paul Falkowski looks "under the hood" of microbes to find the engines of life, the actual working parts that do the biochemical heavy lifting for every living organism on Earth. With insight and humor, he explains…
The multitudes of this book are not the ones envisioned by Walt Whitman. Rather, they are bacteria, viruses, protozoa, and other microbes that each of us carries. The human body is more microbial than human, with bacteria alone outnumbering human cells by almost 10 times.
As Yong puts it, “We cannot fully understand the lives of animals without understanding our microbes and our symbioses with them.” Not just the lives of animals, but of plants too, as this book makes clear.
With advanced degrees in biochemistry and an award-winning stint as a writer at The Atlantic, Yong has the chops to get the science right and the skills of a journalist to weave the science and sketches of scientists together into compelling stories. The book’s subtitle is a nod to Darwin (“There is grandeur in this view of life”) and gets at the big-picture perspective gained by looking at the smallest organisms, the microbes.

Your body is teeming with tens of trillions of microbes. It's an entire world, a colony full of life.
In other words, you contain multitudes.
They sculpt our organs, protect us from diseases, guide our behaviour, and bombard us with their genes. They also hold the key to understanding all life on earth.
In I Contain Multitudes, Ed Yong opens our eyes and invites us to marvel at ourselves and other animals in a new light, less as individuals and more as thriving ecosystems.
I almost put this book down when Marra started to describe what happened one early morning off the coast of Iceland, where he was trying to measure photosynthesis by marine microbes. A day earlier, he had filled bottles with seawater spiked with a radioactive form of carbon, carbon-14, and thrown the bottles overboard to incubate in the ocean. Now he had to retrieve them. As Marra recounted how the ship rolled in huge waves whipped up by 55-knot winds, my stomach churned as I remembered similar experiences on other vessels, in other seas.
Luckily for me and perhaps other seasick-prone readers, Hot Carbon returns to land for several chapters to sketch out the discovery of carbon-14 and its use in C14-dating historical artifacts such as the Shroud of Turin and in unraveling the mechanism of photosynthesis.
In the last part of the book, Marra returns to the ocean and outlines how carbon-14 is used to figure out the age of deep oceanic waters, the speed of ocean currents, and the rate of primary production by marine microbes. These topics take on even more importance because of their connection to climate change. Even when they aren’t “hot,” the science and the scientists introduced in this book are always fascinating, despite the queasy part.
There are few fields of science that carbon-14 has not touched. A radioactive isotope of carbon, it stands out for its unusually long half-life. Best known for its application to estimating the age of artifacts-carbon dating-carbon-14 helped reveal new chronologies of human civilization and geological time. Everything containing carbon, the basis of all life, could be placed in time according to the clock of radioactive decay, with research applications ranging from archeology to oceanography to climatology.
In Hot Carbon, John F. Marra tells the untold story of this scientific revolution. He weaves together the workings of the many disciplines that…
Coastal redwoods and Douglas firs are among the biggest organisms on the planet, yet these and other trees can only reach such spectacular heights thanks to the smallest organisms, the microbes. In fact, nearly all plants have symbiotic fungi that act as surrogate roots to obtain nutrients essential for their growth and survival.
Simard, a Professor of Forest Ecology at the University of British Columbia, has taken this idea further and gathered evidence showing that unrelated trees exchange not only nutrients but also defense signals and other chemical information via their fungal network. But the real protagonist here is the author. As much as I like reading about microbes, what captivated me was Simard recounting her personal journey as a scientist and woman.
NEW YORK TIMES BEST SELLER • From the world's leading forest ecologist who forever changed how people view trees and their connections to one another and to other living things in the forest—a moving, deeply personal journey of discovery
“Finding the Mother Tree reminds us that the world is a web of stories, connecting us to one another. [The book] carries the stories of trees, fungi, soil and bears--and of a human being listening in on the conversation. The interplay of personal narrative, scientific insights and the amazing revelations about the life of the forest make a compelling story.”—Robin Wall…
Humans have devised many ways to turn fossil fuels into carbon dioxide, the most important greenhouse gas now changing Earth’s climate. But the amount of carbon dioxide spewed out by gas-guzzling SUVs and coal power plants is small compared to what microbes release to the atmosphere. Likewise, microbes produce more of two other greenhouse gases, methane and nitrous oxide, than we do. Yet, unlike our actions, the release of greenhouse gases by microbes is balanced by the consumption of those gases by the biosphere. Don’t blame microbes for climate change.
Climate scientists need to understand microbes to predict how the biosphere will react to climate change. Will production or consumption of greenhouse gases go up as the planet continues to warm? Microbes hold the key.
I have been to, and loved, North, Central, and especially East Africa for over fifty years. Only six times have I been to Africa on holiday; more often, perhaps twenty or more times, as a television producer. Working in Africa gains a perspective of reality that the glories of vacation do not. Each has its place, each its pitfalls like stalled plane rides with emergency landings in the bush or attacks by wildlife. But, in the end, the magic of the “otherness,” what an old friend called “primitava” captures one’s soul and changes your life.
Keen to rekindle their love of East African wildlife adventures after years of filming, extreme dangers, and rescues, producer Pero Baltazar, safari guide Mbuno Waliangulu, and Nancy Breiton, camerawoman, undertake a filming walking adventure north of Lake Rudolf, crossing from Kenya into Ethiopia along the Omo River, following a herd of elephant making their annual migration.
Stumbling onto an elephant poaching, the team become embroiled in true financing of terrorism for al Shabaab –ivory sales–and are determined to stop the slaughter at any cost. Ivory trade financing terrorism involves UN refugee camps with two hundred thousand displaced Somali persons, powerful…
A documentary team hiking through East Africa collides with a gang of deadly poachers, in this gripping adventure by the author of Kidnapped on Safari.
Years of filming, extreme dangers, and daring rescues have taken their toll on documentary producer Pero Baltazar and his team. To relax and reconnect with the East African wildlife they love, Pero organizes a walking safari for him, his camerawoman Nancy Breiton, and their elite guide Mbuno Waliangulu. Still, Pero has trouble truly disconnecting from work. When the team comes across a herd of elephants making their annual migration north of Lake Rudolf, Pero decides…
