The famous `Chipko` movement is associated with option 4, saving trees. This movement originated in the Himalayan region of India in the 1970s. It was a grassroots environmental movement led by local villagers, especially women, to protect forests from deforestation and commercial logging. The term "Chipko" literally means "to hug" or "to cling onto," which symbolized the villagers embracing the trees to prevent them from being cut down. The movement aimed to raise awareness about the importance of forests for maintaining ecological balance, preventing soil erosion, and preserving water sources. The Chipko movement gained significant attention and succeeded in bringing about policy changes and facilitating community-based forest management initiatives. It has been recognized as a pivotal environmental movement that inspired similar movements globally.
