Children are advised to write their senators and representatives in Congress about policies they disagree with. The ideas underlying environmental materials are often unrealistic. Humans are villains and nature is the victim. Good A book about Antarctica for first graders shows a helicopter flying near the nests of penguins.

Earthquakes and volcanoes are natural and a natural haze hangs over the Smoky Mountains. Many animal species became extinct without human intervention. Climate changes naturally, from Ice Ages to warm periods of lush vegetation and back.
