They did such a good job that, by 1926, no gray wolf packs were left in the park. Over the following decades, virtually every other part of the park's ecosystem was affected by the loss of the wolves --- from the animals who were their prey, to the plants that were the food for that prey, to the streams that were sheltered by those plants --- and the landscape was in distress. So, starting in 1995, in an attempt to reverse course, the government reintroduced gray wolves to the park. Over time, animal populations stabilized, waterways were restored and a healthy ecosystem was recreated across the land. It's a striking transformation, and a fascinating tale of life's complicated interdependencies.Jude Isabella's thoroughly researched, expert-reviewed text and Kim Smith's beautiful nature art bring science to life in this captivating story of renewal. Readers will recognize just how complex an ecosystem is and learn about the surprising interconnectedness of its members. Biodiversity, ecosystems, the food chain, habitats, needs of living things and the importance of human stewardship of the environment are all covered through this real-life example, offering direct links to earth and life science curriculums. Food web infographics help reinforce the information. A glossary and index add to the book's usefulness.

    Army nurses. But when the Japanese attack on Pearl Harbor in 1941 blasted the United States into World War II, 101 American Army and Navy nurses serving in the Philippines were suddenly treating wounded and dying soldiers while bombs exploded all around them. The women served in jerry-rigged jungle hospitals on the Bataan Peninsula and in underground tunnels on Corregidor Island. Later, when most of them were captured by the Japanese as prisoners of war, they suffered disease and near-starvation for three years. Pure Grit is a story of sisterhood and suffering, of tragedy and betrayal, of death and life. The women cared for one another, maintained discipline, and honored their vocation to nurse anyone in need—all 101 coming home alive.The book is illustrated with archival photographs and includes an index, glossary, and timeline

    And just as compelling is the way the book is structured—hopscotching from country to country not by location but by type of attraction.

Then, while in Mexico, tour the fantastical Naica caves, home to crystals ten times larger than the average person—then, turn the page to Vietnam to a cave so vast you  could fly a 747 through it.

    But in every corner of the world this age-old custom is rapidly changing. From increased trade between countries to the expansion of global food corporations like Kraft and Nestlé, current events are having a tremendous impact on our eating habits. Chances are your supermarket is stocking a variety of international foods, and American fast food chains like McDonald’s and Kentucky Fried Chicken are popping up all over the planet. For the first time in history, more people are overfed than underfed. And while some people still have barely enough to eat, others overeat to the point of illness. To find out how mealtime is changing in real homes, authors Peter Menzel and Faith D’Aluisio visited families around the world to observe and photograph what they eat during the course of one week. They joined parents while they shopped at mega grocery stores and outdoor markets, and participated in a feast where a single goat was shared among many families. They watched moms making dinner in kitchens and over cooking fires, and they sat down to eat with twenty-five families in twenty-one countries--if you’re keeping track, that’s about 525 meals! The foods dished up ranged from hunted seal and spit-roasted guinea pig to U.N.-rationed grains and gallons of Coca-Cola. As Peter and Faith ate and talked with families, they learned firsthand about food consumption around the world and its corresponding causes and effects. The resulting family portraits offer a fascinating glimpse into the cultural similarities and differences served on dinner plates around the globe.
