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.

Did you know that doing good increases happiness, reduces stress, and improves self-esteem? So why not do good today?
We urgently need a new orangutan clinic and are still far from our goal of raising the necessary $200,000 by 30 June.
An easily accessible clinic is more than just a hospital—it ensures a healthy future and freedom for critically #endangered #orangutans in our care.

Ask Elon Musk or other billionaires maybe some from your own country. Regular folks are struggling do good and ask the ones that can afford it.

It's #TongueOutTuesday, and we have a sweet smile for you from Ficz, a #orangutangutan living on Badak Kecil Sanctuary Island.
While delivering supplemental food, our technicians recently observed Ficz sitting on a tree branch at the island's edge, consuming additional fruits such as pineapples, watermelons and bananas.
After eating, Ficz climbed 6 to 10 metres higher in the tree, where he lay down to rest.
Keep on enjoying your island life, Ficz!
