"Rainforest Hero - The Life and Death of Bruno Manser," is the first English biography of the Swiss environmentalist. Famed for leading campaigns to protect the Penan people from the uncontrolled deforestation of their land in Sarawak's forests, Bruno was a fearless activist who lead protests around the world, but who ultimately lost it all in the name of the forests and people he loved. The book was launched in Malaysia last week. We speak to his biographer, Ruedi Suter, about Bruno's extraordinary life.
