Nine-year-old Adam already knows a lot about going green. He loves nature, and likes to pick up litter at the beach, but what can he learn about his city's urban forests? That's where the Green Squad comes in! Eric introduces Adam to some forestry experts, who help him plant his first tree in a nearby park. Kyle takes Adam on a nature walk, where they learn all about biodiversity during a fun scavenger hunt. Adam decides he'd like to do a nature walk again, but this time with other kids in the community! Sigfried helps Adam build the confidence to spread the word of the nature walk to his friends in the neighborhood. Lots of people signed up, and Adam teaches them everything he learned about forest biodiversity from the Squad. Adam proves he's a real friend of the forest! Green Squad sees five passionate and environmentally-savvy young hosts challenge other motivated kids and their families to make fun, eco-friendly lifestyle changes for a healthier planet.
