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.

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.

#pleasehelp our #Orphaned #baby #sunbears like Andrea in the video!
They urgently require a #babyhouse, and we are still far from our goal of raising $50,000 by the end of this month to be able to build this much-needed nursery.
#GiveNow here: bit.ly/Baby-House
While the cubs love to play in the forest during the day, they don't like to sleep alone in forest enclosures at night. The solution is a Baby House where their human surrogate parent can stay close and comfort them.

Although #orangutans are not natural swimmers and usually avoid deep water, they enjoy a refreshing dip.
Small creeks are common in our #OrangutanJungleSchool classrooms in the #rainforests of #borneo, and canals around our pre-release and sanctuary islands prevent the orangutans from escaping.

Looks amazing well done.
Fantastic news 👏 😀
What a great job to have. Keep the good work up. Love job like that
You are all so amazing for taking care of these precious souls
Hey people! Stop buying products that contain palm oil. Most of the crap that Americans buy like cookies and sugary cereal and sugary pre-packaged treats have palm oil in them. These animals' territory is being destroyed to plant palm oil plantations and you're helping them to do that. He responsible and make your cookies at home with better ingredients.
Thank you for taking such wonderful care of these majestic creatures!!
And they just the most gentle of wild animals
Where is it? Would love to volunteer!
Many blessings to you all, today and always ❤️
