environmental influence on humans

Think of all the animals and plants on Earth today. There are millions! But, in the history of Earth there are many more that have gone extinct. In this colorful volume, readers get a crash course in how and why a species may become extinct. Including understandable information about what scientists believe happened when life began, evolution, the dinosaurs, and how all of these plays a role in the ecosystems of today, this book is essential to the young reader's science library.

From problems with agriculture to greenhouse gases released by the burning of fossil fuels, scientists know why Earth is heating up. But around the world, many leaders have been slow to make the changes needed to combat climate change. Many kids today are aware of the climate crisis, and this book takes them through the causes of it as well as examples--like wildfires and the melting polar ice--that show how a warmer world climate is harming Earth. Age-appropriate solutions are presented throughout the book, encouraging readers to take charge of the future of Earth in their own way.
