It's too late for Jono to be rehabilitated into the wild.
His plight symbolises the fast approaching extinction of his species, which shares 97 per cent of human DNA. Even the Indonesian Government admits orangutans will probably be gone from the wild in 50 years.
The destruction of Borneo's and Sumatra's jungles for palm oil plantations makes extinction a near guarantee. But wildlife smugglers, and people who buy the babies as pets, have sped up the process.
'The demand is always there'
A former orangutan smuggler, who is now working as an informant, told us how babies are ripped from their mothers.
He claimed at least three were being taken from the jungles each week and trafficked mainly through Thailand to third nations — particularly in the Middle East, where private ownership of an exotic rainforest animal is a big status symbol.
The informant told us the smugglers often use commercial flights and pay off corrupt officials — information backed up by other sources who spoke, on and off the record.
Mr Wiek runs several sanctuaries and programs across South-East Asia. Originally from the Netherlands, he's a pioneer in wildlife protection.
The return of the babies to Sumatra is his ultimate aim, but rehabilitation of orangutans is arduous and costly. Even if they are returned one day, he worries about their fate.
"Unfortunately, we have found out lately that some of the orangutans that were shipped back to Indonesia that we actually rescued from illegal captivity and the trade have ended up in commercial zoos in Indonesia where they are being bred without any kind of system, without any plan, just only for commercial reasons," he said.
Gone in 50 years?
Wiratno, who goes by one name, is Indonesia's Director General of Natural Resources and Ecosystem Conservation and oversees orangutan protection.
He is a realist about the future of the species, which lives in the wild in only two places — Borneo and Sumatra.
"According to experts, they have maybe 50 years," Wiratno said.
"It's difficult to protect the orangutan in the wild.
"Considering the population and new cities and infrastructure, it's hard to save orangutans."
