To celebrate Van Mahotsav Week, as a part of the NDTV-Dettol Banega Swachh India Campaign, we meet a man who started planting trees when he was 11 years old way back in 1977. Meet Swami Prem Parivartan, also known as Peepal Baba, he is the founder of Give Me Trees Trust, one of the largest community based voluntary tree planting campaign in India with over 10,000 volunteers. The campaign has a record of planting over 20 million trees, and over 1.25 crore Peepal and Neem trees across India.
