In the second episode of "A small acorn", Nate and Amy explore the role that trees play in addressing the climate crisis.  Nate gives a great explanation of the carbon cycle, and there are two interviews: Blake Lawrence from Cool Effect about how trees remove greenhouse gases from the atmosphere and whether some trees remove more carbon dioxide than other trees. Then they talked to Julie Coop, the Urban and Community Forestry Coordinator with the Massachusetts Department of Conservation and Recreation. Keep an ear out for Nate's tree joke.
