Although I always loved planting trees, I never used to get into the grassroot level. Recently, Aditya, a SJCE student and volunteer at Vivekananda youth forum convinced me to start tree planting in a different way; No laborers or money involved but instead we do the task ourselves. We dig the pits ourselves, ask the homes around to provide us with decomposable waste, plant the trees, provide thorn protection and water it. Every day, we make it a point to talk to at least two neighbours. I was never so convinced about this kind of grassroot level work until now.
