Part of John Muir's appeal to modern audiences is that he not only explored the American West and wrote about its beauties but also fought for their preservation. His successes dot the landscape and are evident in all the natural features that bear his name: forests, lakes, trails, and glaciers. Here collected are some of Muir's finest wilderness essays, ranging in subject matter from Alaska to Yellowstone, from Oregon to the High Sierra.

An invisible world of astonishing complexity is all around you. A world so small you can’t see it with the naked eye. A world so crowded that its population staggers the mind. A world in which you participate every day - often without even knowing it. The inhabitants of this world are trillions of bacteria, viruses, fungi, and other organisms, collectively known as microbes. Hundreds of thousands could fit on the period at the end of this sentence. And many play a powerful role in your life.

In these 24 lectures, The Great Courses teams up with the Smithsonian’s National Zoo and Conservation Biology Institute, to take you behind the scenes of the animal world. Dr. Moore has crafted a wonderful introduction to zoology that brings you up close and personal with a breathtaking variety of animal species through the eyes of a trained zoologist.

Gerald Durrell's last book, The Aye-Aye and I, records his final animal-collecting expedition, a trip to Madagascar in 1990, and his efforts to save the elusive and mythical lemuroid known as the Aye-Aye. Prompted by the country's radical deforestation and slash-and-burn agriculture, Durrell, his wife, and their team of zoologists embark on a mission to capture and conserve the species - distinguished by its "giant, chisel-like teeth", "round, hypnotic eyes", and large "spoon-like ears".

Thanks to an ongoing revolution in the science of meteorology, we can now understand how extreme weather conditions arise, produce far more accurate forecasts, and know how to protect ourselves when dangerous conditions develop. The Science of Extreme Weather is your field guide to the worst that Earth’s atmosphere can inflict. In 24 exciting, informative, and potentially life-saving half-hour lectures aimed at weather novices and amateur forecasters alike, you gain a surprisingly powerful tool in the face of such overwhelming forces: knowledge.

Dr. Catherine Kleier invites us to open our eyes to the phenomenal world of plant life and to the process she calls “Natura Revelata”, the joy of celebrating and learning from the secrets of nature. As Dr. Kleier shares her knowledge with contagious excitement for her subject, she emphasizes the middle ground: Instead of focusing on cell microbiology or the study of ecosystems and habitats, she stresses the basic biology, function, and the amazing adaptations of the plants we see all around us.

In The End of the End of the Earth, which gathers essays and speeches written mostly in the past five years, Jonathan Franzen returns with renewed vigour to the themes - both human and literary - that have long preoccupied him. Whether exploring his complex relationship with his uncle, recounting his young adulthood in New York or offering an illuminating look at the global seabird crisis, these pieces contain all the wit and disabused realism that we’ve come to expect from Franzen....

The Emmy Award-winning creator of Gasland tells his intimate and damning, personal story of our world in crisis. Josh Fox turns the rapid-fire shocks that are remaking the very fabric of our lives - writing as a first responder, a reporter, a documentarian, and an activist - into art, literature, and at least one answer to the question of what the future holds.

Many consider Theodore Roosevelt to be America’s most conservation-minded president. Throughout his presidency, he worked to preserve endangered animals and their habitats. In this 1907 speech to Congress, he states, “The conservation of our natural resources and their proper use constitute the fundamental problem which underlies almost every other problem of our national life.” Hear this speech to experience Roosevelt’s conservationist fervor firsthand.

We are complacent. We bask in the idea that Canada holds 20% of the world’s fresh water - water crises face other countries, but not ours. We could not be more wrong. In Boiling Point, best-selling author and activist Maude Barlow lays bare the issues facing Canada’s water reserves, including long-outdated water laws, unmapped and unprotected groundwater reserves, agricultural pollution, industrial-waste dumping, boil-water advisories, and the effects of deforestation and climate change. This will be the defining issue of the coming decade, and most of us have no idea that it is on our very own doorstep.

How the Government Got in Your Backyard distills the science, the politics, and the unbiased, nonpartisan truth behind hot-button environmental issues from pesticides to global warming. By clearly representing what the left says, what the right says, what the science is, and what the facts are, Gillman and Heberlig don't set out to provide the answer - they light the path so concerned citizens can uncover their own true and informed opinion.

His story is now legend. In 1994, after reading The Ecology of Commerce by Paul Hawken, Ray Anderson felt a "spear in the chest." The founder of Interface, Inc., a billion-dollar carpeting manufacturer, realized that his company was plundering the environment and he needed to steer it on a new course. Since then, Interface has cut its greenhouse gas emissions by 82 percent, and the goal is to reach a zero environmental footprint by 2020.

From the purple grasses of August, to the yellow elms of October, to the scarlet oak leaves of November, Henry David Thoreau casts his eye on the brilliant colors of autumn and guides us on a journey through the season's bounty. In this classic essay, first published in 1862, Thoreau delights in fall's foliage and reveals both a practical and philosophical understanding of the changing environment.

Experience this insightful course on the environment. These 12 thought-provoking lectures will give you a distinctly Catholic understanding of the earth. As you explore ecological theology and environmental ethics, you will focus on the themes of origin, crisis, conversion, and action. Using sacred Scripture, the insights of the Franciscan tradition, and modern Catholic social teaching, you will discover a holistic approach to God, humanity, and creation.

Gregory Wrightstone presents the science to assess the basis of the threatening Thermageddon with 60 "inconvenient facts" from government sources, peer-reviewed literature, or scholarly works. The information will likely challenge your current understanding of many apocalyptic predictions about about our ever dynamic climate, and the very framework of the climate-catastrophe argument will be confronted with scientific fact.

From one of the finest scientists and writers of our time comes an engaging record of a life spent in close observation of the natural world, one that has yielded marvelous, mind-altering insight and discoveries. In essays that span several decades, Bernd Heinrich finds himself at his beloved camp in Maine, plays host to annoying visitors from Europe (the cluster fly) and more helpful guests from Asia (ladybugs), and unravels the far-reaching ecological consequences of elephants in Botswana bruising mopane trees.

For decades, it has been nearly universal dogma among environmentalists and health advocates that cattle and beef are public enemy number one. But is the matter really so clear? Hardly, argues environmental lawyer turned rancher Nicolette Hahn Niman in her new book, Defending Beef. The public has long been led to believe that livestock, especially cattle, erode soils, pollute air and water, damage riparian areas, and decimate wildlife populations. In Defending Beef, Hahn Niman argues that cattle are not inherently bad for either the Earth or our own nutritional health.

In Tides: The Science and Spirit of the Ocean, writer, sailor, and surfer Jonathan White takes listeners across the globe to discover the science and spirit of ocean tides. In the Arctic, White shimmies under the ice with an Inuit elder to hunt for mussels in the dark cavities left behind at low tide; in China, he races the Silver Dragon, a 25-foot tidal bore that crashes 80 miles up the Qiantang River; in France, he interviews the monks that live in the tide-wrapped monastery of Mont Saint-Michel; in Chile and Scotland, he investigates the growth of tidal power generation.

The most joyful emanation produced by a colony of bees is known as the “song of increase”—declaring that the hive is flourishing and the bees are happy in its abundance. Song of Increase takes us inside the world of the honeybee to glean the wisdom of these fascinating creatures with whom...

In the spirit of the diaries of Antarctic explorers Robert Falcon Scott and Ernest Shackleton, McNeil mixes travelogue, popular science, and memoir to examine the history of our fascination with ice. In entering this world, McNeil unexpectedly finds herself confronting her own upbringing in the Maritimes, the lifelong effects of growing up in a cold place, and how the climates of childhood frame our emotional thermodynamics for life.
