The Chipko movement or Chipko Andolan was to save trees or conservation of forests in India where people prevent trees from being cut down.
The idea of Chipko movement was of his wife and the action was taken by him. Gaura Devi was one of the pioneers of the movement.
The loggers came to cut the trees in the forest. Gaura Devi led 27 of the village women and confronted the loggers from cutting down the forest. The women resorted to hugging the trees to stop them from being felled. This went on into late hours and stopped loggers from cutting down the trees.
