Adopt an orphaned orangutan
Orangutans are on the brink of extinction. Help provide the care and rehabilitation
they need to return to the wild.
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.

Amazing experience 🔥💥🔥💥 i will never forget this mission 🧡🧡🧡🦧
Iwill never forget the 2 weeks volunteering in Samboja Lestari ❤️❤️
Thank you very much for looking after these amazing living creatures that 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, by destroying their natural forests in Indonesia and Borneo to plant Palm oíl trees just because Palm oíl IS cheap!!!! The internacional community MUST inform consumers about It and ban this appalling business and those Who buy those products containing Palm oíl MUST be aware of its terrible consequences... I always write this because many people do not know about It and we can help by not buying those products containing Palm oíl
