One Simple Thing is an environmental service learning project that was created in San Francisco cafes by public school students to show that you can make a positive difference in your community by doing one simple thing. The One Simple Thing coloring book is narrated by Sammy the Seagull who tells the true story of San Francisco school kids who decided to start a campaign to remind people of a simple way to reduce what they consume. The story takes you on a fun and meaningful eco journey that you are able to color in as you go. Check out more about One Simple Thing here and the coloring book here.
