The events that took place in the Silent Valley region can be arranged in the following order:
The movement started in 1973 to protect the Silent Valley reserve forest. In 1976, Kerala Sasthra Sahitya Parishad (KSSP), the largest popular-science organisation in Kerala, joined the protest.
Citizens and the KSSP exerted pressure on the government through widespread awareness programs, publications, petitions, and appeals in the court.
A case was appealed in the Kerala High Court against the clear-felling of trees in the area, and the sustained efforts of the campaigners compelled the government to stop the project.
In the end, Silent Valley was declared a national park in 1985, and it stands as a testimony to the power of people’s actions.
