Twelve-year-old twins Nick and Eryn and their robot stepsiblings, Jackson and Ava, try to save humanity from killer robots.

"Asteroids come in all shapes and sizes--and hit our planet in them, too. But what happens if a catastrophically large one approaches earth? By looking on the ground at historical asteroid craters and present-day falls, and up into space for the big ones yet to come, a wide variety of scientists are trying to figure out how to track asteroids--and how to avoid devastating impacts in the future."--

Sixty-five million years ago, a comet or asteroid larger than Mount Everest slammed into the Earth, inducing an explosion equivalent to the detonation of a hundred million hydrogen bombs. Vaporized detritus blasted through the atmosphere upon impact, falling back to Earth around the globe. Disastrous environmental consequences ensued: a giant tsunami, continent-scale wildfires, darkness, and cold, followed by sweltering greenhouse heat. When conditions...

Here is a wide-ranging adventure in becoming a citizen scientist by an award-winning writer and environmental thought leader. As Mary Ellen Hannibal wades into tide pools, follows hawks, and scours mountains to collect data on threatened species, she discovers the power of a heroic cast of volunteers—and the makings of what may be our last, best hope in slowing an unprecedented mass extinction. Digging deeply, Hannibal traces today’s tech-enabled...

In the final days of humanity, a dedicated scientist gives the spark of life to nine of his creations. The world has turned into an unrecognizable landscape of machines and spare parts, but this group of nine finds that if they band together, their small community might just be able to change the course of history. When rag doll 9 first comes to life, he finds himself in a post-apocalyptic world where all humans are gone. It is only by chance that...

Presents the names, physical characteristics, and places of origin of a variety of extinct animals, arranged chronologically into eras, periods, and epochs, and discusses times of mass extinction.

"Today, an ancient world is vanishing right before our eyes: the age of giant animals. Over 40,000 years ago, the earth was ruled by megafauna: mammoths and mastodons, saber-toothed tigers and giant sloths. Of course, those creatures no longer exist, and there is only one likely reason for that: the evolution and arrival of the earth's only tool-wielding hunter, the wildly adaptive, comparatively pint-sized human species. Many more of the world's...

Inviting us to meet wild species on our own terms in a range of ecosystems spanning the globe, this radical new kind of environmental journalism connects humans to nature in a more empathetic way than ever before and encourages us to defend the natural world before it’s too late.

"Information about some of the more important and interesting endangered animals of Europe, including the animal's common name, scientific name, and conservation status; also includes a map showing the range of each animal featured; and a glossary, additional resources, and an index"--

A photograph of an extinct animal evokes a greater feeling of loss than any painting ever could. Often black and white or tinted sepia, these remarkable images have been taken mainly in zoos or wildlife parks, and in some cases depict the last known individual of the species. Lost Animals is a unique photographic record of extinction, presented by a world authority on vanished animals. Richly illustrated throughout, this handsome book features photographs...
