Gach is a Bengali word. It means Tree. Trees play a pivotal role in maintaining the ecological balance. Trees have been the core of ancient Indian culture, scriptures, and lives. Unfortunately, that culture is diminishing today. The so-called ‘civilized' world is emerging at the stake of the rampant ravaging of greens. A perfect blend of the scientific outlook, cultural heritage, and proper education is the need of the hour. Gach Green Hands Social Welfare Trust works passionately towards this goal to achieve sustainability in our society.
