In this episode, Hari M. R. speaks about the unforgettable experience of meeting the legend – Prof. (Dr) Akira Miyawaki – in Japan. Though confined to a wheel chair due to age-related problems, Prof. Miyawaki continues to work, and encourage people to simulate natural forests wherever possible. He has already planted four crore trees and created 4000 forests. Even in his 92nd year, he inspires his fellow-citizens to conduct a tree planting festival.
