Reports of global warming's catastrophic effects are everywhere: in newspapers, on the nightly news, even on movie screens. The subject can be so overwhelming that young people are often left with the thought, What can "I" do? In "This Is My Planet, " Jan Thornhill gives young readers the tools they need to live their own lives more ecologically -- and ultimately, to improve the life of the planet. The book takes a comprehensive look at climate change, beginning with basic information about how the planet works and moving through an in-depth look at human societies and three specific environments -- polar, ocean, and land. Although she doesn't shy away from the truth, Thornhill offers hope, showing where action can make a difference and providing evidence of the Earth's amazing resilience and adaptability. Never preachy or alarmist, this amazing book trusts young readers with the facts, allowing them to form their own intelligent opinions. A multitude of full-color photographs enhance Thornhill's engaging, informative text.
