We may love to see amazing, exotic animals like gibbons up close, but how does it feel to be a gibbon trapped in a cage at the zoo?
As this video from Elephant News reveals, you can hear the answer in their voice. The wild gibbon sounds strong, curious and free. The captive gibbon sounds desperate, bored and stressed. You can see the difference, too, as wild gibbons climb, leap and explore, and captive gibbons just cling to the fence and stare.
How would you rather live?
