Millions of children are busy with projects to save the Earth. But we all would be more effective at resolving today's pressing environmental issues if we had a clearer understanding of the ecological principles behind them. With this lively guide to the essentials of ecology, Ernest Callenbach provides a pocket-sized introduction to the wonderful complexity of life on Earth—and our part in it.Callenbach uses everyday, nontechnical language to explain sixty basic ecological concepts. These brief, information-packed entries are arranged alphabetically and amply cross-referenced. Thus the reader can move freely around a dynamic network of ideas, gaining easy access to the new thinking that scientists, environmentalists, politicians, government officials, business people, and concerned citizens everywhere are using to seek a sustainable future for humanity.As timely as today's news, Ecology includes current findings on the microscopic beings that first made plant and animal life possible and now regulate global temperature and oxygen levels—a dramatic new story of the intricate interconnections of all life on Earth. Finally we have a book that equips us to take informed personal and political action with the ecological wisdom needed for the twenty-first century.

    It's everything. From lions hunting as a pride to penguins huddling together to keep from freezing in the bitter Antarctic winter, many animals are dependent on complex social relationships for their survival. Powerful dynasties lay claim to vast swathes of territory, fighting off rivals and securing their hunting grounds for generations to come.Dynasties offers an immersive insight into the shifting hierarchies of animal families. Each chapter follows a different dynasty, from the Marsh Lions of the Masai Mara to rival packs of painted wolves, from a tiger protecting her newborn cubs to a chimpanzee troop and the penguin colonies of the Antarctic. Alongside tender moments when bonds are strengthened through grooming and play, the book charts the rivalries that tip the balance of power, when family members turn against each other and younger animals grow strong enough to challenge for control.With over 200 stunning photographs and insights from the crew of the BBC series, Dynasties reveals in astonishing detail the intricate social lives of our planet’s most fascinating animals.

    Sure, it's even simpler than it was before. Of course, you don't have to worry about fertilizer or poor soil ever again because you'll be growing above the ground. However, the best feature is that anyone, anywhere can enjoy a square foot garden - children, adults with limited mobility, and even complete novices can achieve spectacular results. But, let's get back to the ten improvements. You're going to love them: 1. New Location - Move your garden closer to your house by eliminating single-row gardening. Square foot gardens need just 20% of the space of a traditional garden.2. New Direction - Locate your garden on top of existing soil. Forget about pH soil tests, double-digging (who enjoys that?), or those never-ending soil improvements.3. New Soil - The new "Mel's Mix" is the perfect growing mix. We give you the recipe, and best of all, you can even buy the different types of compost needed.4. New Depth - You only need to prepare a SFG box to a depth of 6 inches! It's true - the majority of plants develop just fine when grown at this depth.5. No Fertilizer - The all new SFG does not need any fertilizer - ever! If you start with the perfect soil mix, then you don't need to add fertilizer.6. New Boxes - The new method uses bottomless boxes placed above ground. We show you how to build your own (with step-by-step photos).7. New Aisles - The ideal gardening aisle width is about three to four feet. That makes it even easier to kneel, work, and harvest.8. New Grids - Prominent and permanent grids added to your SFG box help you visualize your planting squares and properly space them for maximum harvest.9. New Seed-Saving Idea - The old-fashioned way advocates planting many seeds and then thinning the extras (that means pulling them up). The new method means planting a pinch - literally two or three seeds - per planting hole.10. Tabletop Gardens - The new boxes are so much smaller and lighter (only 6 inches of soil, remember?), you can add a plywood bottom to make them portable. Of course, that's not all. We've also included simple, easy-to-follow instructions using lots of photos and illustrations. You're going to love it!

    The complex behavior of birds recounted here demonstrates that birds have sophisticated mental abilities previously unrecognized by conventional avian research. Ackerman supports her thesis with descriptions of the behavior of an entertaining variety of birds from across the world. She brings scientific research alive with personal field observations and accounts of her encounters with colorful and fascinating birds. Throughout, Ackerman reminds readers that birds are thinking beings--their brains are wired differently than those of mammals, giving them increased brain power despite their small size. She further makes the case that bird intelligence shows that humankind is not alone in using language and tools or constructing complex structures and manipulating other creatures.

    This authoritative yet accessible study is the ultimate astronomy lesson. Combining fascinating and often alarming scenarios that seem plucked from science fiction with the latest research and opinions, Plait illustrates why outer space is not as remote as most people think. Each chapter explores a different phenomenon, explaining it in easy-to-understand terms, and considering how life on earth and the planet itself would be affected should the event come to pass. Rather than sensationalizing the information, Plait analyzes the probability of these catastrophes occurring in our lifetimes and what we can do to stop them. With its entertaining tone and enlightening explanation of unfathomable concepts, Death from the Skies! will appeal to science buffs and beginners alike.

    A total eclipse of the Sun will be visible from within a narrow corridor that traverses the United States.

    Throughout these adventures, Rinella found himself contemplating his own place among the 14,000 years’ worth of buffalo hunters in North America, as well as the buffalo’s place in the American experience. At the time of the Revolutionary War, North America was home to approximately 40 million buffalo, the largest herd of big mammals on the planet, but by the mid-1890s only a few hundred remained. Now that the buffalo is on the verge of a dramatic ecological recovery across the West, Americans are faced with the challenge of how, and if, we can dare to share our land with a beast that is the embodiment of the American wilderness. American Buffalo is a narrative tale of Rinella’s hunt. But beyond that, it is the story of the many ways in which the buffalo has shaped our national identity. Rinella takes us across the continent in search of the buffalo’s past, present, and future: to the Bering Land Bridge, where scientists search for buffalo bones amid artifacts of the New World’s earliest human inhabitants; to buffalo jumps where Native Americans once ran buffalo over cliffs by the thousands; to the Detroit Carbon works, a “bone charcoal” plant that made fortunes in the late 1800s by turning millions of tons of buffalo bones into bone meal, black dye, and fine china; and even to an abattoir turned fashion mecca in Manhattan’s Meatpacking District, where a depressed buffalo named Black Diamond met his fate after serving as the model for the American nickel. Rinella’s erudition and exuberance, combined with his gift for storytelling, make him the perfect guide for a book that combines outdoor adventure with a quirky blend of facts and observations about history, biology, and the natural world. Both a captivating narrative and a book of environmental and historical significance, American Buffalo tells us as much about ourselves as Americans as it does about the creature who perhaps best of all embodies the American ethos.
