Bolpur (West Bengal): " What gas are we breathing in?" a grey-haired elderly man asked a group of schoolchildren with a pleasant smile on his face. Pleased with his friendly demeanor, the children then happily listened to him on the importance of planting trees and saving the environment.
This is Dr. Surpiyo Kumar Sadhu is a school teacher by profession and an environmental activist by passion. For the last 35 years, his neighbors are used to seeing him going to school riding his bicycle. Despite knowing how to ride a motorcycle, Sadhu prefers his bicycle as it is eco-friendly.
It is adorned with placards saying "abandon plastic", "plant trees," and "save the environment." Asked about the reason behind using such placards Sadhu said " people sometimes stop and read what is written on my bicycle. If after reading them one plants a tree it is a matter of great satisfaction for me."
