Sunderlal Bahuguna Obituary: A messiah of forests who taught us how to hug Chipko movement founder Sunderlal Bahuguna His name may be synonymous with the Chipko movement â the practice of hugging trees to prevent their felling â but Sunderlal Bahuguna, a practising Gandhian, was passionate about many other social issues as well, including womenâs empowerment, the anti-liquor movement, removal of caste discrimination, promotion of nonviolence and the agitation against large dams. The 94-year-old activist died of Covid-related complications in the All India Institute of Medical Sciences, Rishikesh, where he was admitted on May 8 after testing positive for Covid-19. The end came around noon on May 21; but as he departed, he left behind a valuable legacy of social activism based on Gandhian and humanitarian principles, fired with compassion and a strong sense of responsibility.
