Today marks the 51st annual Earth Day celebration, and the Cornell Cooperative Extension of Rockland is marking the occasion by streaming environmental presentations the entire day. The 2021 “Earth Day Stream-a-thon” begins at 10 with a reading of the Dr. Seuss story “The Lorax.” There’s a new presentation every hour through 8pm, including a Spring Home Energy Check-up and a Backyard Composting Demo Tour.
