About This Lesson
Tree planting can reduce summertime temperatures, thereby reducing air-conditioning bills and trapping some of the greenhouse gases responsible for global warming. In this lesson, students learn how trees renew our air supply by absorbing carbon dioxide and producing oxygen, and how they clean our air by filtering out dust and greenhouse gases. Students also learn to identify tree species and the species that threaten them, and develop a plan for protecting and promoting trees in their own community.
