He visits Norwegian megafarms that use genetic techniques once pioneered on sheep to grow millions of pounds of salmon a year. He travels to the ancestral river of the Yupik Eskimos to see the only Fair Trade–certified fishing company in the world. He makes clear how PCBs and mercury find their way into seafood; discovers how Mediterranean sea bass went global; challenges the author of Cod to taste the difference between a farmed and a wild cod; and almost sinks to the bottom of the South Pacific while searching for an alternative to endangered bluefin tuna.Fish, Greenberg reveals, are the last truly wild food — for now. By examining the forces that get fish to our dinner tables, he shows how we can start to heal the oceans and fight for a world where healthy and sustainable seafood is the rule rather than the exception.

    He was a city boy, unsure of what lay ahead. When he entered the forest, which would go on to become one of the last strongholds of wild tigers, it had a profound effect on him, changing his life forever.For the next forty years, he studied nearly 200 Ranthambhore tigers, spending every waking moment in close proximity to these magnificent animals. Of the various tigers he observed a handful became extra special, and it is these which come to glorious life in this book. They include Padmini, the Queen Mother, the first tiger the author got to know well; Genghis, the master predator, who invented a way of killing prey in water, the first time this had been observed anywhere in the world; Noon, one of his all-time favourites, who received her name because she was most active in the middle of the day; Broken Tooth, an exceptionally gentle male; Laxmi, a devoted mother, whose methods of raising her cubs revolutionized tiger studies; Machli, the most famous tigress in Ranthambhore, and several more.

    Thanks largely to YouTube clips posted by the sloth orphanage in Costa Rica, sloths have attracted a vast audience of admirers. Instead of seeing them as ridiculous anachronisms of which we know little, they have turned into creatures considered by many to be the most endearing on earth.Over much the same period, scientific investigations have also changed our view of sloths. No longer are they seen as total misfits in the modern world but, in the words of one specialist sloth investigator, they are 'masters of an alternative lifestyle'.In this wonderfully entertaining celebration of this most unique of creatures, William Hartston reveals the fascinating history of the sloth, from the prehistoric ground sloth to modern pygmy sloths in Panama, explores the current state of the science of sloths and reveals the truth behind sloth behaviour.

    edition features an extra 16 pages of insights into the book, including author interviews, recommended reading, and more.

    Fathoms: The World in the Whale blends natural history, philosophy, and science to explore: How do whales experience ecological change? Will our connection to these storied animals be transformed by technology? What can observing whales teach us about the complexity, splendour, and fragility of life? In Fathoms, we learn about whales so rare they have never been named, whale songs that sweep across hemispheres in annual waves of popularity, and whales that have modified the chemical composition of our planet’s atmosphere. We travel to Japan to board the ships that hunt whales and delve into the deepest seas to discover the plastic pollution now pervading the whale’s undersea environment. In the spirit of Rachel Carson and Rebecca Solnit, Giggs gives us a vivid exploration of the natural world even as she addresses what it means to write about nature at a time of environmental crisis.

    As Joel Reynolds launches a legal fight to expose and challenge the Navy program, marine biologist Ken Balcomb witnesses a mysterious mass stranding of whales near his research station in the Bahamas. Investigating this calamity, Balcomb is forced to choose between his conscience and an oath of secrecy he swore to the Navy in his youth.When Balcomb and Reynolds team up to expose the truth behind an epidemic of mass strandings, the stage is set for an epic battle that pits admirals against activists, rogue submarines against weaponized dolphins, and national security against the need to safeguard the ocean environment. Waged in secret military labs and the nation’s highest court, War of the Whales is a real-life thriller that combines the best of legal drama, natural history, and military intrigue.

    But now, suddenly, the turtles are dying, ravaged by a mysterious plague that some biologists consider the most serious epidemic now raging in the natural world. Perhaps most important, sea turtles aren't the only marine creatures falling prey to deadly epidemics. Over the last few decades diseases have been burning through nearshore waters around the world with unprecedented lethality. What is happening to the sea turtle, and how can it be stopped? In this fascinating scientific detective story, Osha Gray Davidson tracks the fervent efforts of the extraordinary and often quirky scientists, marine biologists, veterinarians, and others racing against the clock to unravel a complicated biological and environmental puzzle and keep the turtles from extinction. He follows the fates of particular turtles, revealing their surprisingly distinct personalities and why they inspire an almost spiritual devotion in the humans who come to know them. He also explores through vivid historical anecdotes and examples the history of man's relationship to the sea, opening a window onto the role played by humans in the increasing number of marine die-offs and extinctions. Beautifully written, intellectually provocative, Fire in the Turtle House reveals how emerging diseases wreaking havoc in the global ocean pose an enormous, direct threat to humanity. This is science journalism at its best.

    They evolved from land-roaming, dog-like creatures into animals that move like fish, breathe like us, can grow to 300,000 pounds, live 200 years and roam entire ocean basins. Whales fill us with terror, awe, and affection--yet we know hardly anything about them, and they only enter our awareness when they die, struck by a ship or stranded in the surf. Why did it take whales over 50 million years to evolve to such big sizes, and how do they eat enough to stay that big? How did their ancestors return from land to the sea? Why do they beach themselves? What do their lives tell us about our oceans, and evolution as a whole? Importantly, in the sweepstakes of human-driven habitat and climate change, will whales survive?Nick Pyenson's research has given us the answers to some of our biggest questions about whales. Nick's rich storytelling takes us to the cool halls deep inside the Smithsonian's priceless fossil collection, to the frigid fishing decks on Antarctic whaling stations, and to the blazing hot desert of Chile where scientists race against time to document the largest fossil whalebone site on earth. Spying on Whales is science writing at its best: an author who is an incredible, passionate writer, at the forefront of his field, on a topic that invokes deep fascination.

    Rich illustrations, systematic resumes, and extensive citations make it a valuable references source.

    It's also a book full of entertainment and wonders. In The Song of the Dodo, we follow Quammen's keen intellect through the ideas, theories, and experiments of prominent naturalists of the last two centuries. We trail after him as he travels the world, tracking the subject of island biogeography, which encompasses nothing less than the study of the origin and extinction of all species. Why is this island idea so important? Because islands are where species most commonly go extinct -- and because, as Quammen points out, we live in an age when all of Earth's landscapes are being chopped into island-like fragments by human activity. Through his eyes, we glimpse the nature of evolution and extinction, and in so doing come to understand the monumental diversity of our planet, and the importance of preserving its wild landscapes, animals, and plants. We also meet some fascinating human characters. By the book's end we are wiser, and more deeply concerned, but Quammen leaves us with a message of excitement and hope.

    Bruce Franklin shows how menhaden have shaped America’s national—and natural—history, and why reckless overfishing now threatens their place in both. Since Native Americans began using menhaden as fertilizer, this amazing fish has greased the wheels of U.S. agriculture and industry. By the mid-1870s, menhaden had replaced whales as a principal source of industrial lubricant, with hundreds of ships and dozens of factories along the eastern seaboard working feverishly to produce fish oil. Since the Civil War, menhaden have provided the largest catch of any American fishery. Today, one company—Omega Protein—has a monopoly on the menhaden “reduction industry.” Every year it sweeps billions of fish from the sea, grinds them up, and turns them into animal feed, fertilizer, and oil used in everything from linoleum to health-food supplements. The massive harvest wouldn’t be such a problem if menhaden were only good for making lipstick and soap. But they are crucial to the diet of bigger fish and they filter the waters of the Atlantic and Gulf coasts, playing an essential dual role in marine ecology perhaps unmatched anywhere on the planet. As their numbers have plummeted, fish and birds dependent on them have been decimatedand toxic algae have begun to choke our bays and seas. In Franklin’s vibrant prose, the decline of a once ubiquitous fish becomes an adventure story, an exploration of the U.S. political economy, a groundbreaking history of America’s emerging ecological consciousness, and an inspiring vision of a growing alliance between environmentalists and recreational anglers.

    They were very nearly right. That the panther still exists at all is a miracle--the result of a desperate experiment that led to the most remarkable comeback in the history of the Endangered Species Act. And no one has told the whole story--until now.With novelistic detail and an eye for the absurd, Craig Pittman recounts the extraordinary story of the people who brought the panther back from the brink of extinction, the ones who nearly pushed the species over the edge, and the cats that were caught in the middle. This being Florida, there's more than a little weirdness, too.An engrossing narrative of wry humor, sharp writing and exhaustive reportage, Cat Tale shows what it takes to bring one species back and what unexpected costs such a decision brings.
