"In the seventh book in the Exploring Our Community series, the five friends learn all about how to reduce plastic pollution. It's Nick's birthday, and he wants to celebrate by challenging his friends to a No Plastics Day. While going a whole day without using single-use plastic, the five friends learn about how much plastic surrounds us in our daily lives; the garbage patch gyres in the oceans; plastic in our food chain; what plastic is made of (science page); changes we can make to use less plastic; and alternatives to single-use plastics. The book concludes with fun ideas for a No Plastic Challenge."--
