We have a perennial fascination with sharks. Portrayed in the media and popular culture as killing machines, we are awed by their power and strength. But the shark is so much more—a marvel of the sea, they have evolved over 450 million years into more than 500 species, from the bioluminescent kitefin to the tiny dwarf lantern shark, the sociable lemon shark to the cow shark, which can birth up to 100 pups in one litter. Bringing balance to the ocean’s ecosystem, our planet is at serious risk when these amazing creatures are threatened.

As the fracture lines between nations grow ever wider, how do we relate to each other, to the land on which we live and the world around us? Are we united enough to see protection of the natural environment as a priority? These are the questions Raynor asks herself as she embarks on her most ambitious walk to date with her husband Moth—from the dramatic beauty of the Cape Wrath Trail in the north-west corner of Scotland, to the familiar territory of the South-west Coast Path.

The Atlantic grey seal is globally rare—there are fewer grey seals in the world than African elephants—and Britain hosts 40 per cent of this world population. Over the course of a year in their lives, Susan Richardson comes to know a colony of seals, watching as it is hit by storms in the autumn pupping season, experiencing sociable winter haul-outs and sympathising as the colony scratch and fidget through their annual moult.

With Mountain Madness, Clinton Crockett Peters chronicles his travels and personal transformation from a West Texas evangelical to mountain guide to humbled humanist after a near-fatal injury in Japan's Chichibu Mountains. From 2007 to 2010, Peters lived in Kosuge Village, nestled in central Japan's peaks, where he was the only foreigner in town. This essay collection profiles who he was before Japan, why he became obsessed with mountains, and his fallout from mountain obsession. Ultimately, the collection asks, how can landscape create and end identities?

This classic is an essential handbook for anyone who studies, surfs, protects, or is fascinated by the ocean, with a wealth of information based on theory and statistics, but also anecdotal observation and personal experience. It brought to the general public understanding of the awesome and complex power of the waves. This revision from Kim McCoy updates the book's relevance in the time of climate change. One of the most significant effects of global warming will be sea-level rise. What will this mean to waves and beaches, and what effects are we already seeing?

A decade ago, farmed Atlantic salmon replaced tuna as the most popular fish on America’s dinner tables. We are told salmon is healthy and environmentally friendly. The reality is disturbingly different. In Salmon Wars, investigative journalists Douglas Frantz and Catherine Collins bring listeners to massive ocean feedlots where millions of salmon are crammed into parasite-plagued cages and fed a chemical-laced diet. The authors reveal the conditions inside hatcheries, where young salmon are treated like garbage, and at the farms that threaten our fragile coasts.

By 1930, no place in the world was less well explored than Greenland. The native Inuit had occupied the relatively accessible west coast for centuries. The east coast, however, was another story. In August 1930, Henry George Watkins (nicknamed “Gino”), a twenty-three-year-old British explorer, led thirteen scientists and explorers on an ambitious expedition to the east coast of Greenland and into its vast and forbidding interior to set up a permanent meteorological base on the icecap, 8,200 feet above sea level.

It’s summer, and John Connell finds himself—like so many others—confined to his local area, the opportunity to freely travel and socialise cut short. His attention turns to the Camlin river—an ever-present source of life for his hometown’s inhabitants and, for John, a site of boyhood adventure, first love, family history and local legend. He decides to canoe its course with a friend, a two-day trip requiring physical exertion and mental resilience. Despite the world growing still around them, the river teems with life—a symphony of buzzing mayfly and jumping trout.

Where nature writing meets humor—a raucous, hilarious look at life in the high desert of Nevada, from the author of Raising Wild and Rants from the Hill.

In this informed and lyrical collection of interwoven essays, Lisa Knopp explores the physical and cultural geography of the Mississippi, Missouri, and Platte rivers she has come to understand and cherish. At the same time, she contemplates how people experience landscape, identifying three primary roles of environmental perception: the insider, the outsider, and the outsider seeking to become an insider. Viewing the waterways through these approaches, she searches for knowledge and meaning.

Michael Branch “earned his whiskers” in the Great Basin Desert of northwestern Nevada, where he lives off the grid with his wife and two curious little girls. Shifting between pastoral passages on beauty found in the desert and humorous tales of being a father, Raising Wild offers an intimate portrait of a landscape where mountain lions and ground squirrels can threaten in equal measure. With Branch’s distinct lyricism and wit, this barren landscape becomes a place resonant with the rattle of snakes, the plod of pronghorn antelope, and the rustle of juniper trees.

When Rebecca Giggs encountered a humpback whale stranded on her local beach in Australia, she began to wonder how the lives of whales might shed light on the condition of our seas. How do whales experience environmental change? Has our connection to these fabled animals been transformed by technology? What future awaits us, and them? And what does it mean to write about nature in the midst of an ecological crisis? In Fathoms, Giggs blends natural history, philosophy and science to explore these questions with clarity and hope.

Five stunningly large forests remain on Earth. These megaforests are vital to preserving global biodiversity, thousands of cultures, and a stable climate, as John W. Reid and Thomas E. Lovejoy argue in Ever Green. Megaforests serve an essential role in decarbonizing the atmosphere, and saving them is the most immediate and affordable large-scale solution to our planet's most formidable ongoing crisis. Reid and Lovejoy offer practical solutions to address the biggest challenges these forests face, from vastly expanding protected areas to supporting Indigenous forest stewards.

In the late 2000s, when the three-decade-long Left Front rule in West Bengal was crumbling, Parimal Bhattacharya began to travel outside the well-trodden urban centres to different parts of the region - from the Sundarbans to tribal Jangalmahal, from the outskirts of Kolkata to villages on the Bangladesh border, from the floodplains of the Hooghly to the forests of Simlipal in neighbouring Odisha.

Think of a platypus: they lay eggs (that hatch into so-called platypups), they produce milk without nipples and venom without fangs and they can detect electricity. Or a wombat: their teeth never stop growing, they poo cubes and they defend themselves with reinforced rears. Platypuses, possums, wombats, echidnas, devils, kangaroos, quolls, dibblers, dunnarts, kowaris: Australia has some truly astonishing mammals with incredible, unfamiliar features. But how does the world regard these creatures? And what does that mean for their conservation?

Ben Short has a successful career in advertising, a flat in a trendy part of London, a flashy motorbike. But after years of suffering with anxiety, he's a wreck. A drastic change is needed. For a time, he finds solace working with a forester, then as an apprentice to a Gypsy woodman, setting up home in a dilapidated wagon with just a rescue dog for company.

Following the Irish coast in a clockwise direction, acclaimed ecologist Richard Nairn travels by boat, on foot and sometimes by air to visit the best remaining wild places, including islands, cliffs, beaches and dunes. The result is a unique mix of nature, history, science and a reflection on the author’s personal experiences of exploring Ireland’s coast. By viewing the Irish coastline from the sea, Richard gains a unique perspective on the island. And along the way, he recalls a lifetime spent studying nature.

Science Be Dammed is an alarming reminder of the high stakes in the management - and perils in the mismanagement - of water in the Western United States. It seems deceptively simple: Even when clear evidence was available that the Colorado River could not sustain ambitious dreaming and planning by decision-makers throughout the 20th century, river planners and political operatives irresponsibly made the least sustainable and most dangerous long-term decisions.

Jake Fiennes is on a mission to change the face of the English countryside. Mass farming, crop science and industrial chemicals have destroyed the majority of our natural landscape and wildlife over the last century. Land Healer is the story of Fiennes' ambition to bring back our flora and fauna—by reclaiming our traditions and trialling new experiments which could restore our symbiosis with our land, and save our shared future.

Kim Stanley Robinson first ventured into the Sierra Nevada mountains during the summer of 1973. He returned from that encounter a changed man, awed by a landscape that made him feel as if he were simultaneously strolling through an art museum and scrambling on a jungle gym like an energized child. He has returned to the mountains throughout his life—more than a hundred trips—and has gathered a vast store of knowledge about them. The High Sierra is his lavish celebration of this exceptional place.
