He founded Sanctuary Asia in 1981 at the suggestion of Fateh Singh Rathore who told him to "start a wildlife magazine. So that city people learn to appreciate wildlife and do less damage!". He founded Cub Magazine. He has authored numerous book on wildlife including, most recently: India Naturally, The Bandhavgarh Inheritance, The Sundarbans Inheritance, The Bharatpur Inheritance, The Kaziranga Inheritance, The Corbett Inheritance and The Periyar Inheritance. He writes for both English and local language newspapers and magazines in India. He has produced over 30 conservation-related documentaries.
He founded Kids for Tigers, the Sanctuary Tiger Programme in the year 2000. A mass contact campaign, this reaches out to over 650 schools in 15 Indian cities and covers one million children. Their mission is simple; Kids for Tigers wishes to convey to adults that: "The tiger will only be saved if its forests are saved. By saving these forests, India protects over 600 of its purest rivers and in the process the forests sequester and store carbon in the most effective way possible."
