What is a celebration without fun activities? Earth Day activities for seniors don’t have to be extravagant. Something as Earth-friendly as planting a tree together can be therapeutic and relaxing as well as a conscious effort to give back to our planet. Trees help to reduce greenhouse gases, clean our everyday pollution, and secure soil in place to prevent erosion. If planting a tree is inspiring, an organized group tree hug could be just as much fun with music and shared stories.
