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.

you know what would really help BOS and other wildlife, STOP SHOPPING FOR CRAP YOU DON'T NEED, Easter and Christmas are fictional fairy tales, save your gift buying and giving for real celebrations like birthdays. And stop manufacturing crap as a pretence to save Wildlife.
Genetic #Milestone!
After over two decades of work, researchers have successfully sequenced the complete #genomes of six #ape species: the chimpanzee, bonobo, Bornean #orangutan, Sumatran orangutan and the Siamang gibbon.
The results, published in the journal 'Nature' by a team of 123 researchers from various countries, will help scientists understand what differentiates humans from other apes. For example, researchers often examine the genetic variations in ape DNA that contribute to their resistance to certain diseases.
