In 1987, Swedish teacher Eha Kern and her young students in Fagervik, Sweden became concerned after viewing a documentary that ended with disturbing images of tropical rainforests being burned and cleared. They created a campaign to gather support to protect a piece of Rainforest in Costa Rica. Eventually, children in 44 countries contributed to the effort they started. That piece of land became the Children's Eternal Rainforest (or el Bosque Eterno de los Niños)
In 2002, conservation visionaries Rachel and Dwight Crandell continued this mission and founded Friends of the Rainforest (originally known as the Monteverde Conservation League U.S., Inc.). Friends of the Rainforest began as a United States-based sister organization to the internationally-recognized Monteverde Conservation League (MCL) of Costa Rica.
