This really has quite a substantial amount of information for a Rookie Reader.  Each two-page spread is dedicated to another idea for practical things individuals can do to help keep the planet clean.  It begins with a page dedicated to “invisible” garbage, encouraging kids to walk or ride bikes to places nearby to avoid contributing to air pollution and taking showers instead of baths to avoid wasting water.  It goes on to suggest growing one’s own food, composting, using reusable containers, donating things you’ve finished with, recycling, etc.  It ends by sharing some real-life stories about ways some creative things others have done to get their communities involved in this effort.
