The stunning image was taken during International Animal Rescue's orangutan rescue efforts back in 2013.
The photo shows two of the men, Syifa Sidik and Argitoe Ranting, who helped carry animals to safety after their forest homes were bulldozed for a palm oil plantation.
Today, two years after this photo was snapped, environmental devastation and rampant forest fires have ravaged the homes of so many orangutans, putting their lives in even more danger.
"Recently the team has had to contend with smog, smoke and fires," Lis Key, of IAR, told The Dodo. "The future of orangutan populations will never be secure without the involvement and commitment of the palm oil industry to protecting sufficient habitat for them to survive and to thrive. We can only hope that the impact of the fires in Indonesia will act as a wake up call to those responsible for allowing such devastation and they will take determined action to prevent it from happening again."
