Amit Nath Hazra, 43, embarked on his mission in 1979. A grade IV employee in a private firm, he invests a large portion of his Rs 3,000 salary on Calcutta’s future. "I buy year-old saplings, plant and nurture them," says Hazra. He’s never received any monetary help and has declined awards, preferring to remain anonymous. "I have my share of well-wishers, but my detractors outnumber them," he says nonchalantly. From the very beginning, he had to face opposition. "Many people never understood what I was doing—I was purchasing saplings, digging pits along roads and planting them. For some unfathomable reason, people didn’t like me doing it. Under the cover of darkness, they used to destroy the fencings and uproot the saplings. People have even cut down trees that I once planted. Such incidents are painful. These trees are like my children."
