These are tough times for the orangutan.
Not only does the tree-dwelling primate live on just two islands in south east Asia, they are also in line for extinction in the wild if the destruction of their last remaining habitat continues.
But as these pictures show the great ape can still sometimes rely on their human cousins to help them out in their time of need.

Workers at theTanjung Puting National Park, home to 6,000 orangutans, have been preparing some of their residents for release back into the wild.
It is, however, no mean feat. The apes need to be weighed, measured and medically checked to make sure they have the best chance of survival back in the wild.
Primatologist Dr. Birute Mary Galdikas, who has been studying primates for 40 years believes it is critical we protect the orangutan's in their ongoing battle against extinction
Galdikas says: 'If they go extinct, we will have one less kin to call our own in this world.'
Dr. Birute Mary Galdikas has spent decades researching the lives of primates and highlighting the threats they are facing
There are an estimated 60,000 orangutans left in the wild, mostly living in small and scattered populations in the rainforests of Borneo and Sumatra.
With an estimated 300 football fields of trees cleared every hour the future is looking bleak for the primate species that shares more than 95% of the human gene pool.
