The Silent Valley in the Western Ghats is a Pristine Stretch of tropical rain forest in Kerala and is one of the most bio-diverse places on the earth. In the 1970 and 1980s, plans to construct a dam across the Kunthi river, proposed by the Kerala State Electricity Board (KSEB) sparked a fierce debate about the future of this unique ecosystem. A monumental campaign led by environmentalists, scientists, teachers, students and local communities succeeded at the end and the Silent Valley Rainforest was declared as a national park in 1984.
