“Kassinger gives these Plain Janes their time in the sun…Great reading.”
—Ira Flatow, NPR’s “Science Friday”
"Algae are among the earth's oldest life-forms, pervasive in everything from pond scum to crude oil. Kassinger explains their history and biology, and makes a persuasive case for their future importance."
—New York Times Book Review
“No organisms are more important to life as we know it than algae. In Slime, Ruth Kassinger gives this under-appreciated group its due. The result is engaging, occasionally icky, and deeply informative.”
—Elizabeth Kolbert, New York Times-bestselling author of the Pulitzer Prize-winner The Sixth Extinction
"Kassinger has found in algae an undervalued topic truly worthy of closer attention...In the end, Kassinger has us rooting for pond scum—it might just save us yet."
"In spite of having studied algae for more than 30 years, I learnt much from Slime...Compelling...There is something for everyone, from committed phycologists to people who hitherto (but hopefully no longer) regarded algae as an inconvenience or worse. Blanket weed may never seem the same again."
"Slime illustrates the important role algae have played in the world...Overall, Slime gives a distinct view into these underappreciated organisms and demonstrates our intertwined history with algae. Hopefully, it will help readers see algae in a different light."
"Fascinating and relevant...As Kassinger finds unique nuggets within algae's backstory and possible future, she unravels amazing, microscopic details of this vital resource...Where it gets really interesting is her detailed explanation of the large role algae played in the complicated, multistep process of human evolution, supplementing our ancestors’ diets with iodine and the omega-3 oil DHA (docosahexaenoic acid), both essential ingredients for developing larger brains. And it has continued to serve as a nutritious food source for many cultures ever since...Kassinger has penned a wondrous story of this multifaceted, often misunderstood microorganism whose existence is vital to our own."

"We often look for big solutions, but the reality is that the smallest things often offer hope. This globetrotting book showcases the 'algae innovators' (the phrase of the month) exploring what we can learn from these often-ignored plants."
“A book full of delights and surprises. Algae are the hidden rulers of our world, giving us oxygen, food, and energy. This is a beautiful evocation of the many ways that our past and future are entangled in their emerald strands.”
—David George Haskell, author of The Songs of Trees and Pulitzer Prize-finalist The Forest Unseen
"Deep and enlightening...Readers will learn more about algae than they ever imagined (and relish every minute of it). Comparisons to Mary Roach and Susan Orlean are well-deserved, and Kassinger’s erudite and wide-ranging approach should entice readers with a wide range of interests, from food to fashion, bioengineering, marine biology, farming, and general fascination with the wonders of nature. Gardeners will welcome Kassinger's latest, and everyone else will feel lucky to discover this winsome writer."

“Slime is a revelation! Algae has the power to cool the planet, replace plastics, fuel vehicles, and feed the world. This visionary book belongs in the hands of every policy maker, business leader, and engaged citizen looking for answers to our most pressing problems. It also happens to be a delightful read in the tradition of Susan Orlean, Mary Roach, and Michael Pollan. Ruth Kassinger turns a reporter’s eye to the natural world and finds an epic narrative there, populated by dedicated scientists, intrepid chefs, and starry-eyed visionaries.”
—Amy Stewart, New York Times-bestselling author of The Drunken Botanist and the Kopp Sisters novels
