Our Vision
Our vision is a world where orangutans are free from the threat of extinction and can live in the wild, unharmed by humans.
back to their home.
our two sanctuaries.
The Problem
There are numerous threats to the viability of the remaining wild orangutan population in Indonesia and Malaysia. The primary threat is the loss of habitat with up to 80% of suitable forest in Indonesia and Malaysia having been lost in the past 20 years. Other threats, which often go hand-in-hand with the destruction of the rainforest, are the illegal pet trade and poaching.

Please remember that these amazing living creatures are being turned into endangered species by despicable multinationals like Ferrero which makes Nutella or those making oreo cookies or Cadbury products, to name just a few, which keep on destroying their natural forests in Indonesia and Borneo to plant Palm oíl trees just because Palm oíl IS cheap!!!! The international community must inform consumers about It,fine those multinationals and ban this appalling business and those Who buy those products containing Palm oíl MUST be aware of its terrible consequences... Please,lets read the labels and lets not buy those products containing Palm oíl for the sake of these innocent and unique living creatures 🦧🦧🦧
