Dangerous radioactive materials released into the air continue to threaten the health of the ocean and people around the world today. Topics include how movements in the earth's crust below water can cause seismic waves , the evacuation of more than 300,000 people from their homes near the power plant, contamination of crops and water, decontamination and repair work, and continued concern about leaking radiation from the power plant.
Animals have become extinct for many reasons. The most famous example, the extinction of the dinosaurs, may have been the result of an asteroid hitting Earth or an Ice Age freezing them to death. Prehistoric mammoths and saber-toothed cats may simply have been hunted to extinction. Today, animals such as elephants, zebras, tigers and leopards, some wolves, and many kinds of primates may still face extinction due to climate change, habitat loss, hunting, poaching, and pollution. This fascinating book introduces and explains the designations of endangerment from extinct in the wild to vulnerable. Children are also introduced to fossils as a way of learning about animals that lived long ago.
