NASHOBA SCHOOLS - An unnatural calamity has befallen Santa’s elves in the North Pole. Too many toys are returning for recycling, and no matter how hard they try, they just can’t keep up. To save his magical workshop and the North Pole, Santa is going to need all the help he can get.   This is the story told in “Respect Your Toys” by author J. Anthony Garreffi, of Lancaster, who has been visiting students at Florence Sawyer School (Bolton), Mary Rowlandson School (Lancaster) and Center School (Stow) to read his book and share the important message of reducing waste, reusing materials and recycling.   “This empowering story teaches children of all ages that even our smallest, unintended actions can have huge consequences,” Garreffi said. “It’s exciting to teach students about how they can make a difference by reducing waste and recycling.”   As part of Garreffi’s educational school visits, he asks students to donate broken or worn out toys to be recycled. In return, students receive a free copy of one of his two books, “A ‘ChristMax’ Carol,” a story about compassion, or his second book, “Respect Your Toys.” Both books contain music to augment Garreffi’s messages, which he sings while playing his guitar. With the support of Hasbro toys and Terracycle, a zero-waste recycling company, all broken toys donated by the students will be 100 percent recycled.   “We are grateful to Garreffi for spending time with our students to help them understand how each of them and their families can make our environment a safer and cleaner place to live,” said Reina Rago, coordinator of Extended Learning and Enrichment for the Nashoba Regional School District. “There’s nothing better than watching a child’s eyes sparkle when they realize they count and can make a difference in the world.”
