It has been more than 35 years since the sound of a gunshot on September 1 1990 reverberated across the nation, leaving a lasting mark on the hearts of those who love Thailand’s forests.

Sanctuary officials, students and conservationists took part in a ceremony to remember the late Thai environmental activist, Seub Nakhasathien, who ended his life 32 years ago to draw public attention to poachings and encroachments.
