Children's Literature - Marilyn Courtot
When something is called extinct it is either known to have died out or has not been seen in the wild for 50 years or more. Scientists have come up with words to describe animals that no longer exist or are or in danger of disappearing. There is a full page chart, defining each term, plus its shorthand code and an example of an animal in each category. For example, Critically Endangered (CR) describes animals that are at high risk of dying out in the wild. The example shown is the Sumatran orangutan. The text then moves on to describe the dinosaurs, which became extinct about 65 million years ago, but no one knows for sure why. The most commonly accepted theory is that earth was hit by an asteroid, which among other disasters caused a large dust cloud to obscure the sun and thus disrupted the food chain. Many paleontologists believe that birds evolved from dinosaurs and thus the species changed and survived in its current form—the birds that we see. Climate change, habitat loss, and hunting have become the modern threats to many animals. This book provides several recommendations to prevent extinction, including decreasing the use of plastics and avoiding pollution of the environment, which are certainly good for both people and animals. The final spread pictures animals of yesterday and today and asks kids to match them up with look-a-like living animals (answers are provided). The book is filled with interesting information and the kind of facts that kids will love sharing at home or with friends. The full color illustrations are excellent and bring the points home. There is a short glossary and index on the closing page. All in all, a good addition for any school, home or public library. Reviewer: Marilyn Courtot
