Grasslands [PDF ebook] 

Here is the perfect introduction to the places where animals and plants live and grow. Each book explores one of the world’s major biomes and describes its climate, the people who live and work there, threats to the environment, and measures that are being taken to protect it. This book looks at the world’s grasslands and how animals and plants interact for survival in extreme climates-from the tropical glasslands of Africa’s savanna to the wide open prairies of North America and the isolated steppes of Asia.
