    She couldn't become a politician. She couldn't even vote. But Elizabeth Cady Stanton didn't let that stop her. She called on women across the nation to stand together and demand to be treated as equal to men-and that included the right to vote.

Lynne Cherry’s contrasting illustrations of the lush valley and the eventual polluted river deliver an astonishing look at our dramatic need for conservation efforts. This pictorial history of the river, edging towards a hopeful scene of modern-day descendants of both Native Americans and European settlers who come together to combat pollution and restore the beauty of the river, is an intelligent tale that shows young readers how they can do their part in taking care of the world around them, one river at a time.

    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.
