We investigate one company's alleged role in massive forest fires that have blighted South-East Asia for two decades. Tony Wenas, the boss of Indonesian firm, April, says he is now being totally transparent about his firm's fire-prevention measures, and its policies preventing illegal logging within its business. We also hear from a California start-up, The Earth Genome, that champions the environmental cause by putting a price on the assets of the natural world. Its co-founder Steve McCormick explains how far you can go in putting a value on nature. And we send the 主播大秀's Rahul Tandon off on a Hindu pilgrimage in India.
