Alert! Earth in Danger

The scenarios are unnerving: an asteroid on a collision course with Earth, melting polar caps, and deadly pollution, to name a few. However, readers will be drawn to this book that asks the question: What if? Each narrative presents a tragic situation and explores how technology and science could be used to help mankind prepare for the worst...if it ever happens. Features such as maps, diagrams, and fact boxes supply additional information to support reader comprehension.
